Building 074, Room 00-012I am a PhD student at the University of Freiburg supervised by Prof. Frank Hutter. My Ph.D. position is part of the Small Data Initiative, where I work on project B01: Transfer- and meta-learning in deep networks for human brain-signal analysis. I'm particularly interested in Hyperparameter Optimization and Meta-learning.
I finished my Masters at the University of Freiburg in 2023. During my Masters I participated in two AutoML competitions which focused on AutoML for diverse tasks. I ranked third in the AutoML Decathlon competition and ranked first in all three phases (phase 1, phase 2, phase 3) of the follow-up AutoML Cup competition.
