Ph.D. Student at
Technical University Braunschweig
I am a Ph.D. student at Technical University Braunschweig under the supervision of Timo de Wolff. I received my Bachelor of Science from Goethe-University in Frankfurt in 2017 and my Master of Science from the same university in 2019. My primary mathematical interest is polynomial optimisation, particularly, studying sums of nonnegative circuits as a certificate of polynomial nonnegativity. You can find out more about my research here.
Office hours: By appointment — please send me an e-mail.
News: My new article "Initial Application of SONC to Lyapunov Stability of Dynamical Systems" with Timo de Wolff is now available on arXiv!
I am currently mostly working from home.
Please contact me via e-mail.
