Behind every research project are people, ideas, and stories. To mark the International Day of Women and Girls in Science 2026, we spoke with PhD students, postdoctoral researchers, and professors whose curiosity, passion, and dedication drive their work. We asked them: What are you researching? What inspired you to pursue a career in science? And what advice would you give to girls and young women considering a future in science?
Lea Bold, Optimization-Based Control
For me, pursuing a career in science wasn’t a long-planned step; in fact, I had completely ruled it out. Then I was asked if I could imagine pursuing a Ph.D., and I didn’t want to let such an opportunity pass me by. Today, I’m about to graduate, and looking back, it was the best path for me. My research focuses on data-driven approximation of systems that are constantly changing over time. Since we derive the models purely from data, an important question arises: How reliable is the approximation, and will the model really behave the same way as the real-world system? To address this, I’m working on mathematical methods to derive error bounds. I also aim to show that the surrogate models can not only reproduce the data but also remain stable under control and regulation. My advice to young female scientists: Ask questions! Seek out conversations with others and ask for support when you need it. Not knowing something is not a sign of weakness. And when things get tough: Hang in there. Phases like these, where you doubt everything, are completely normal and are just part of the process.
