Michael Dröscher: “We still have lots of good ideas”

"We still have lots of good ideas"

Michael Dröscher, Secretary General and Treasurer of the GDNÄ, talks about new momentum for the society, highlights of the meeting in Bremen and his own plans for the future.

Professor Dröscher, we are conducting this interview at the beginning of 2026. You have long been responsible for the Society of German Natural Scientists and Physicians: for eleven years as its Secretary General and for nine years as its Treasurer. Where does the GDNÄ stand today?
Not only are membership numbers stable, we can even hope for growth. This positive trend is by no means a given. Most scientific societies today are struggling with declining membership numbers and often lack young talent. This was also the case for us for a long time. 

What led to the turnaround?
The decisive factor was the founding of the GDNÄ's Young Network, known as jGDNÄ for short. The network is open to scientists and medical professionals up to the age of 32 and is developing splendidly. The first self-organised congress took place in Heidelberg in June 2025, and the next one is planned for 2027. The young members are very committed and are bringing new momentum to our venerable society.

How do they manage that?
For example, they are active on our LinkedIn channel, which operates under the name "Gesellschaft Deutscher Naturforscher und Ärzte" (German Society of Natural Scientists and Physicians). I recommend that all members take a look and become followers. We also owe the jGDNÄ a debt of gratitude for bringing us the attention of YouTuber and author Jacob Beautemps, whom we awarded the Oken Medal in December for his outstanding contributions to science communication. The young members are currently in the process of establishing regional structures, with groups in Aachen, Heidelberg, Bochum and Greifswald. Together, we have drafted rules of procedure that define the rights and obligations of the jGDNÄ. The rules are to be adopted at the next meeting in Bremen. 

What motivates these young people?
I believe they sense that we are happy to have them here. We give them a lot of freedom and involve them wherever possible. For example, representatives of the jGDNÄ always attend board meetings. Many appreciate the contact with established GDNÄ members and take advantage of the opportunities for further training. For example, we are currently developing a pilot project on medical communication with two-day workshops for our young people. The format fits in well with the theme of Science Year 2026, "Medicine of the Future".

Most members are older than 32. What are your arguments for keeping this group in the GDNÄ? And for attracting new members from this age group?
There are a number of good arguments. Every membership fee, every donation and every bequest supports young people in the natural sciences and medicine, whether in our school programme or in the jGDNÄ. The contributions finance our small but highly efficient office, which makes our many activities possible in the first place. I am thinking, for example, of the Lorenz Oken Medal award ceremony at the Science Forum in Stuttgart, which was very well attended and raised our profile among important target groups . With our website and videos of lectures at the meetings, we contribute to science communication – all of which, of course, costs money. In addition, our members benefit directly from discounts, for example at the meetings and when subscribing to our association's journal, the Naturwissenschaftliche Rundschau. They are also invited to our regional meetings, which we now want to offer more frequently.

A regional meeting took place in Leipzig in the summer of 2025. What happens next?
The Leipzig meeting was a good start. On 13 March, we will continue the series in Bremen; the invitations have been sent out recently. Our scientific director for the next GDNÄ meeting, Professor Michal Kucera, will give a lecture on his climate science research and discuss it with the participants. The event will be hosted by the German Research Centre for Artificial Intelligence in Bremen. Further regional meetings are in the planning stage.

The 134th GDNÄ meeting will take place from 17 to 20 September. How far along are the preparations?
The programme (pdf) is set, and preparations are in full swing. Once again, we have some fantastic lectures and a superb accompanying programme. One highlight is sure to be the public lecture by Professor Ben List, winner of the 2021 Nobel Prize in Chemistry, on the evening of 19 September. The public is also invited to attend the lecture by Professor Thomas Zurbuchen from ETH Zurich on the subject of aerospace. He will speak on the eve of the opening, when we will also be hosting the popular Science Slam "Science in 5 Minutes". The Bremen Senator for Science will give a welcoming address at the opening event. We have once again organised a programme for school pupils, with around 100 pupils from the region and around 50 students taking part. A poster exhibition is planned in the foyer, with prizes for the two best posters. Speaking of which, we will once again be awarding the Alexander von Humboldt Medal for outstanding services to the GDNÄ, and the Society of German Chemists will be presenting the Liebig Medal. The jGDNÄ is organising a student café on its own for the first time. It will be a compact gathering, with all events taking place on one level. The Congress Centre is only a ten-minute walk from the centre of Bremen. One more thing: this time, the closing speech will really be given on Sunday lunchtime so that everyone can get home on time.

It will be your last meeting as Secretary General. Why is that?

I am approaching eighty and am gradually retiring from my honorary positions on boards of trustees and other committees of scientific institutions. My position as GDNÄ Secretary General will be taken over by Professor Stefan Buchholz, with whom I have attended many events over the past few months. I will remain GDNÄ Treasurer until the end of 2027. My term as Chairman of the Administrative Board of the Max Planck Institute for Coal Research will also last until then. After that, I look forward to spending more time with my family and enjoying a more peaceful life.

How do you see the future of the GDNÄ?
As I said, the trend is positive – now we must do everything we can to ensure that it continues. The GDNÄ has held its own in the world of science for 204 years, experiencing heyday and weathering crises. Today, even large scientific societies are fighting for the attention of the public, which does not make things any easier for us. But we have many good ideas that we would like to implement and for which we need funding. As treasurer, I will therefore never tire of appealing to the generosity of our members. It is money well spent, and I vouch for that with my name.

Michael Dröscher, Secretary General and Treasurer of the GDNÄ.

About the person

Professor Michael Dröscher has been treasurer and board member of the GDNÄ since 2017 and its secretary general since 2015. He was born in Kirn an der Nahe in 1949, studied chemistry in Mainz and also completed his doctorate there.  He then took up a position as a research assistant at the University of Freiburg and, at the age of just 31, qualified as a professor in macromolecular chemistry. He continued his academic career first as a private lecturer and, from 1988, as an adjunct professor at the University of Münster.

Michael Dröscher is even more interested in the application of scientific results than in basic research, which is what led him to industry. He started in 1982 as a laboratory manager and in 1984 as a department head at Hüls AG in Marl, North Rhine-Westphalia. He remained at Hüls and its successor companies, Degussa-Hüls and Evonik-Industries AG, for 27 years in various roles. In 1997, Michael Dröscher was appointed managing director of the then newly founded Hüls subsidiary Creavis Gesellschaft für Technologie und Innovation mbH. Five years later, in 2002, Michael Dröscher became innovation manager at Degussa AG, which later became part of Evonik.

Michael Dröscher was also involved in professional associations, including as Chairman of the German Bunsen Society (2005 to 2006) and, from 2010 to 2011, as President of the German Chemical Society and Manager of the CHEMIE.NRW cluster.

He is Chairman of the Board of Directors of the Max Planck Institute for Coal Research in Mülheim and has been a member of several boards of trustees and advisory boards of the Max Planck Society, the Leibniz Association and university institutes.

Lorenz Oken Medal for Jacob Beautemps

Lorenz-Oken-Medaille für Jacob Beautemps

On 3 December 2025, the Lorenz Oken Medal was awarded to science YouTuber Dr Jacob Beautemps at the Science Communication Forum in Stuttgart.

The festive award ceremony was moderated by Professor Michael Dröscher, Secretary General and Treasurer of the GDNÄ. Its Vice President, Professor Heribert Hofer, gave the introduction and presented the medal. 

This was followed by a laudatory speech given by two representatives of the young target audience, both members of the GDNÄ's Young Network. Kevin Yuan is in his first semester of medical school, while Eric Andresen has successfully completed his Abitur and plans to study physics. Heribert Hofer: ‘The two did this with great enthusiasm, with a fine sense of humour, very entertaining and yet very informative about the award winner and his activities.’ It was a brilliant performance that also visibly impressed the honouree.

Jacob Beautemps: ‘It’s wonderful to inspire others’

‘It's wonderful to inspire others’

Jacob Beautemps, science YouTuber and GDNÄ award winner, on the rules of good communication and how he came to not become a teacher.

Dr Beautemps, you are 32 years old, have already won several awards for your approach to science communication, and on 3 December you will also receive the Lorenz Oken Medal from the GDNÄ. What makes you so successful?
I don't know if I'm that successful. But at least I've been active on various media channels for eight years now, and so far I haven't made any major mistakes. As a science YouTuber, I publish two new videos on scientific topics every week – always based on studies and other reputable sources, which I cite transparently, as in a scientific paper. My community likes that, and it has now grown to more than 700,000 people. I also make documentaries for television, such as the series Science for Future on SWR, and contributions to the children's programme Tigerenten Club on ARD. At the beginning of the year, my first book, entitled Rethinking Our Future, was published. Well, everywhere I try to work as accurately as possible and be transparent with my sources.

What is your favourite format?
Definitely YouTube. The medium is uncomplicated, fast and flexible. I have complete freedom in designing the videos; no one interferes. That doesn't mean I don't like to learn new things – for example, from the television professionals I work with. I then use this new knowledge for my videos. For the past year, I have also been running an English-language channel for an international audience. Take a look at The German Science Guy.

@ IdeenExpo

On stage at IdeenExpo 2024 in Hanover, Jacob Beautemps demonstrates how to make ice using nitrogen. Held every two years since 2007, the event aims to inspire young people to take an interest in science and technology.

How do you choose your topics?
I'm particularly interested in topics that will be relevant in the future and topics that are widely discussed but which hardly anyone looks into in any depth. It's always important to relate them to our lives. One example is the heat pump. There was a lot of debate about it and most people didn't even know what the principle behind it was. So I did a deep dive that lasted almost 20 minutes, but really explained the principle. In the end, more than 1.2 million people watched the video. 

Your spectrum ranges from the polio vaccine to noise makers in the jungle to electricity from rain. How do you manage to report competently on all these topics?
Fortunately, I have a great team that helps me with research and implementation. There are currently five of us in the editorial team. Our goal is always to produce scientifically sound videos based on the latest research. 

And if a mistake happens?
That happens, and then it's important to deal with it transparently. I address the mistake in one of the next videos and set the record straight. That builds trust. 

How does the audience react to your posts?
On YouTube, first with click numbers; currently, there are an average of 4.5 million views per month. I am fortunate that I hardly ever have to deal with hostility, and when I do, I don't argue with people, but refer them to the sources, which I always cite. It's nice when I can inspire others. I get comments like: Hey, you got me interested in renewable energies, and now I'm studying it. Or: I report on a start-up, visit it again later and meet people there who became aware of the company through me and now work there. 

There are other successful science YouTubers in Germany. Is that unwelcome competition for you?
On the contrary, we benefit from each other. For example, people who watch a video by Mai Thi often watch one of mine afterwards – and vice versa. We also have different areas of focus. I mostly deal with innovations, while other science YouTubers may focus more on nutrition or medicine. That's the beauty of YouTube: you don't have to fight for airtime like you do on TV, but instead promote each other.

@ Beautemps

Jacob Beautemps interviews Bill Gates and polio survivors. The conversation, which took place in 2023, focused on the international polio initiative, which Gates supports significantly.

At the award ceremony in Stuttgart, you will give a speech and present some rules for successful knowledge transfer. What are they?
I can give a few examples. We know from research how helpful it is to work with questions. This is not just about arousing curiosity with questions. Experiments have shown that specifically addressing misconceptions is very helpful in dispelling them. Without these questions, the same experiments showed that there is hardly any learning effect. Maximum transparency is another point. This includes introducing yourself and your expertise and explaining where the information you are presenting comes from. This creates trust, which is the be-all and end-all of good communication. Messages become particularly memorable when they are visualised and emotionalised. There are lots of tricks for doing this – I will give a few examples in Stuttgart. 

How did you actually get into science communication?
It was a complete coincidence. I actually wanted to become a teacher. While studying physics and social sciences, I worked part-time at Günther Jauch's production company in Cologne, always behind the camera. When I was asked if I could set up a YouTube channel for the company, I did so, but again behind the camera. At some point, I was asked if I would like to get in front of the camera. At first I said no, not really, but in my mid-twenties I did it anyway. Then one thing led to another. 

A doctorate is not essential for your profession. Nevertheless, you decided to do it. Why?
Out of pure curiosity. I was interested in the question of why and how people use educational videos and what makes such videos successful. I conducted a study with around five thousand adults from Germany who frequently watch science videos and came to some interesting conclusions. For example: an important reason for the audience to engage with a topic is the person in front of the camera. This creates a parasocial relationship, the feeling of knowing the other person, even if you have never met them in person. You spend time together, and over time, trust develops. From my findings, I have derived a guide with 17 rules for the best possible production of educational videos. In principle, however, the study can be useful to anyone who wants to communicate competently. The same rules apply when I give a presentation, teach a course or want to explain something that is not entirely trivial. 

What are your plans for the future?
I have many plans, but one project is particularly close to my heart: next year, I want to work with colleagues from the field of science communication to launch an award for innovations made in Germany. Germany is a highly innovative country, and we want to show that to a large audience. At the moment, many people here are too pessimistic. There will be awards in various categories, for example for innovations in the fields of medicine, energy and mobility. The Federal Agency for Breakthrough Innovations will help us to identify the most convincing projects from what we hope will be a large number of applications. We will then present them in videos and let our communities vote on the winners. We are currently looking for partners and asking companies and scientific institutions for their support.

Michal Kucera: “Welcome to a proud city of science”

“Welcome to a proud city of science”

Professor Michal Kucera, Vice President for Research and Transfer at the University of Bremen, talks about his involvement in the GDNÄ Conference 2026 and science in a city where everything is within easy reach.

Professor Kucera, you have taken on the role of Scientific Director for the GDNÄ Conference 2026 in Bremen. What attracted you to this role?
I am familiar with the GDNÄ from my time at the University of Tübingen. I still remember well the meeting organized by Christiane Nüsslein-Volhard, Nobel Prize winner in Medicine and then president of the GDNÄ. With its interdisciplinary lectures and student program, the conference was a model of modern science communication for me. All of this fits in very well with the science city of Bremen, where I have been working for thirteen years. So I was happy to accept when the current president of the GDNÄ asked me to take on the task. 

How can we imagine your work as scientific director?
I prepare the stage for the GDNÄ on site and support it with my contacts in Bremen's science, education, and cultural scene. This involves recruiting speakers, finding good venues for the accompanying program, and establishing contacts with schools and the city administration. I am happy to invest the time and energy required for this. For us, the GDNÄ meeting is a welcome opportunity to demonstrate the strengths of Bremen as a center of science.

Professor Michal Kucera presents his university's AI research at a conference in the Bremen exhibition hall. Next door, in the Congress Centre, the 134th meeting of the GDNÄ will take place.

What are these strengths?
In 2005, the Stifterverband named Bremen the first German “City of Science.” This is testament to the rapid development that universities, institutes, and the entire scientific community in Bremen and Bremerhaven have undergone over the past 50 years. I myself have always been impressed by the high density of scientific institutions located around our campus in the technology park, which are closely networked with each other. The university is at the center, surrounded by high-tech companies and non-university institutes. Distances are short, and the cafeteria is often a common meeting place – which promotes cooperation. With our focus on marine research, artificial intelligence, and robotics, but also on the social sciences, we can compete internationally. In addition, Bremen is a great city that has a lot to offer. People here are proud to live in a city of science and enjoy attending lectures, exhibitions, and discussion events. The people of Bremen are aware of the importance and benefits of science for society.

This fits in with the motto of the 2026 meeting: Knowledge creates benefits – use science.
Yes, also with regard to the application of research, Bremen is a very suitable venue for the GDNÄ.

As Vice President for Research and Transfer at the University of Bremen, you are responsible for the application of research. How do you proceed?
It is important to me to support our researchers in their commitment to transfer and to clearly communicate our appreciation for them. I try to understand what promotes transfer and what hinders it. To this end, I hold many discussions and try to involve colleagues from across the entire spectrum of disciplines at the university. It is also important for us to maintain contact with local players in Bremen, from the cultural scene to business associations such as the Chamber of Commerce and the Industry Club. Close networking is the key to success for the location as a whole.

You have been in office for three years. What has happened in terms of transfer?
We have achieved a lot. One example is the Digital Hub INDUSTRY, where we work with small and medium-sized companies in the region to develop tailor-made digital solutions for the industry of tomorrow. Another example is the transfer center for sustainable materials, matena innovate! center, which was founded in December 2024. We were able to prevail in fierce competition and win the Hamburg-based Joachim Herz Foundation for the promotion of our location. Here, research teams from the university and our partner institutes develop new approaches from research to application maturity. The focus is on topics such as stationary energy storage for renewable energies, sustainable feed for aquaculture, and sensor materials for the hydrogen economy. We are benefiting from a change in the overall climate when it comes to transfer: its importance is increasingly recognized by society, and its image has improved significantly in recent years.

Expedition MSM 111 in Baffin Bay: In the conference room of the research vessel Maria S. Merian, scientists discuss the initial results of a deep-sea drilling project. Together, they attempt to understand the stratification of the ocean floor. “As it later turned out, our initial interpretations were completely wrong,” says Michal Kucera (center), who was the expedition leader at the time.

You are Czech, studied in Prague, earned your doctorate in Sweden, and your scientific career has taken you to the US, the UK, and several universities in Germany. How do you assess the German scientific scene in international comparison?
The freedom of research at German universities is fantastic. They do not have to finance themselves through tuition fees and are therefore less commercially oriented than universities in Anglo-Saxon countries. Teaching is more important there than in Germany, there are many tutorials for students, and the curriculum is more flexible than in Germany. While in Germany it is often a matter of complying with rules, for example with regard to teaching obligations, in the UK teaching is distributed flexibly among the teaching staff according to need. On the other hand, Germany's great advantages are its excellent research funding and its globally unique research infrastructure. These make the country a major scientific power. I, for example, benefit greatly from access to excellent marine science equipment and state-of-the-art research vessels. 

Do you still have time for your own research?
Yes, but unfortunately not as much as I used to. That's why I'm not starting any new large-scale projects at the moment, but am concentrating on evaluating the results of past expeditions. For example, there are samples from a deep-sea drilling expedition that I led in Baffin Bay in 2022. We expect to gain new insights into the melting behavior of the Greenland ice cap in the past, which is important for our future in a warmer global climate. During this expedition, we also collected sediment cores in southern Greenland that contain valuable information about the climate over the last ten thousand years. They will help us understand why the Vikings left their settlements in Greenland in the 15th century after living there for four hundred years. Incidentally, the MSM 111 expedition with the research vessel Maria S. Merian took place as part of the University of Bremen's Cluster of Excellence “The Ocean Floor – Earth's Unexplored Interface,” the continuation of which was recently approved.  

Let's take another look at the GDNÄ conference in 2026: What can participants look forward to?
Fascinating lectures on current topics in the natural sciences and a great accompanying program. For example, a reception is planned at the Bremen Overseas Museum. The museum, with its collection of natural history, ethnology, and trade that is unique in Europe, will celebrate its 130th anniversary in 2026. Another highlight is a visit to Universum Bremen. The popular science center is located directly on the university campus and invites us to participate and experiment during an exclusive guided tour.

Stefan Buchholz: ‘We must not miss out on this development’

‘We must not miss out on this development’

Stefan Buchholz, member of the GDNÄ Executive Board and its designated Secretary General, talks about his career in the chemical industry, artificial intelligence and plans for the future.

Professor Buchholz, you have been a member of the GDNÄ for a long time. How long exactly?
Actually, for more than a quarter of a century. I was brought in by Professor Heribert Offermanns, a gifted chemist and member of the Degussa Executive Board. I worked for him for several years as an executive assistant, writing speeches for him, for example. Mr Offermanns was my mentor – he convinced me of the qualities of the GDNÄ.

What particularly appealed to you?
The wide range of topics and the interdisciplinary approach to the natural sciences. Even as a child, I was interested in nature in all its diversity and fascinated by the infinity of the universe. When it came to choosing a degree course, I found it difficult to decide between chemistry, biology and physics. In the end, I chose chemistry, which in retrospect was the right choice for me.

 In what way?
Because chemistry has many links to other disciplines. The most exciting time in my professional career was the years I spent in biotechnology, where I was able to work with biologists, physicists and engineers, among others. These were wonderful interdisciplinary teams that achieved great results. I am thinking, for example, of fermentatively produced amino acids that replace amino acids obtained from animal material. During the BSE crisis, this was an important and profitable innovation for the company.

Chemical engineer Kai Boldt enters process control data into a large fermenter at the Biotechnology Project House.

You started at what was then Degussa and remained loyal to the company and its successor companies, now Evonik, until your retirement. Were you not tempted by an academic career?
Yes, basically, that was my original goal, but based on my assessment during my studies, I felt that chemistry had been relatively well researched and the basic molecules were already known. Of course, you can still produce an infinite number of new molecules, but that wasn't my path. I was more interested in innovation, in using knowledge for new processes and products. I also found the practical transfer of research results into large-scale production exciting. It's difficult, but it succeeds time and again. One example is the very skin-friendly, nature-identical and biodegradable biosurfactants that one of my project teams developed over the last decade: today, they are used in dishwashing detergents and skin care products, for example. As a biotech manager who worked exclusively with biologists and engineers for several years, I felt very much at home in the chemical industry. 

The German chemical industry is not doing well at the moment. Is there a lack of innovation?
Yes, but not only in terms of new chemical products. We already have a lot of good products. The chemical industry is a mature industry that is undergoing a gigantic transformation. Energy and raw materials are expensive, cheap competition and weak demand are squeezing margins. Consolidation is inevitable; the chemical industry will shrink. At the same time, it is urgently needed, not least to combat climate change and better protect the environment. However, radically new approaches are required. I see opportunities in the combination of chemistry and artificial intelligence, which will give the field a major boost. And we must not miss out on this development.

 © Evonik

In the biotechnology project house, project manager Dr Stefan Verseck takes a sample from a steel container.

That sounds like a good topic for the next GDNÄ meeting in Bremen in 2026.
Yes, a contribution on this topic is indeed planned. Lectures on industrial biotechnology and the electrocatalytic production of green hydrogen are also planned. The Nobel Lecture will be given by Benjamin List from the Max Planck Institute for Coal Research in Mülheim. He will report on his research into organocatalysis, for which he received the Nobel Prize in Chemistry in 2021. 

In the GDNÄ, you are not only group chairman for chemistry, but also designated secretary general. At the beginning of 2027, you will take over the honorary position from Michael Dröscher. What motivates you?
The GDNÄ suits me and my interest in fundamental and interdisciplinary issues. That is what the GDNÄ has stood for for two hundred years. I find that impressive and important, and I am happy to contribute to its future development. 

Do you already have any ideas?
In my studies at the University of the Third Age at Goethe University Frankfurt, I am currently focusing intensively on natural philosophy. This also involves our ability to understand nature and its limits. We are learning a great deal about scientific theories and the history of science and are engaged in lively discussions on these topics. I could also imagine such a range of topics being offered at the GDNÄ. The great popularity of my course shows that there is interest in such fundamental questions.
