What excites you about your research?
The most exciting thing about my research is the opportunity to bring together different disciplines and people. In my working group, colleagues deal with a wide variety of aspects of pharmacy, biology and chemistry. This makes for a lively and inspiring scientific exchange. I find working in academic research particularly appealing because it often holds unexpected developments in store: different pieces of the puzzle have to be put together, and creative and analytical thinking is required. I am not only enthusiastic about my own field of research, but also very interested in other research topics and enjoy reading about advances in these fields.
What solutions can you find in your research for present and future challenges?
In my working group, we are developing novel active substances against mycobacteria, a genus of bacteria that includes species that cause lung and skin diseases, for example – a highly topical issue in view of the increasing resistance to antibiotics worldwide. I see this as an important task for the future, particularly with regard to healthcare in countries with limited access to modern medicine. We are also conducting research into protein capsids. These are ball-like structures made of protein material. We want to adapt them so that they can be used as catalysts in aqueous systems. The aim is to reduce the need for organic solvents in chemical synthesis and thus enable more sustainable processes. Overall, we strive to develop innovative solutions that are both medically and ecologically relevant.
What would you like to pass on to your students, and what would you like to gain from teaching?
I want to encourage my students to practise free and analytical thinking and to develop the self-confidence to question and pursue their own ideas. For me, initiative, creativity and a willingness to learn from mistakes are key elements of a successful career. Teaching others has taught me how important it is to actively seek dialogue with the younger generation. Their perspectives, questions and interests help me to keep an open mind and to convey content in a contemporary way.
What topics are you personally most concerned with at the moment, outside of your research?
In addition to research and teaching, I am also involved in administrative tasks. In my free time, I enjoy spending time with my family, especially outdoors in nature. Activities such as hiking, cycling or simply going on trips together help me recharge my batteries and find a good balance between work and private life.
What do you like most about Freiburg?
What I particularly appreciate about Freiburg is its proximity to the Black Forest and its beautiful historic centre. The city offers a high quality of life, short distances and an open atmosphere – ideal conditions for research, teaching and leisure activities alike.
