Research Profile

I am a Student Researcher at Google DeepMind and a PhD student in Machine Learning at TU Berlin and the Berlin Institute for the Foundations of Learning and Data (BIFOLD). I am also a guest researcher in the ViCCo Group at the Max Planck Institute for Human Cognitive and Brain Sciences. I am mainly advised by Klaus-Robert Müller and co-supervised by Martin Hebart, Simon Kornblith, and Andrew Lampinen. During my PhD, I’ve been part of a Research Collaboration between TU Berlin and Google Brain, where I was advised by Simon Kornblith. Previously, I was a MSc student in IT & Cognition / Computer Science of Isabelle Augenstein and Johannes Bjerva at the University of Copenhagen where I mostly worked on Question Answering and Machine Translation.

My research mainly revolves around representation learning in computer vision. In particular, I try to understand the factors that influence the degree of alignment between human mental and neural network representations and pin down the best way to leverage human inductive biases about object similarity for deep learning models. My goal is to build interpretable foundation models that generalize to downstream out-of-distribution settings. Have a look at my Google Scholar for more information about my (recent) work. Feel free to reach out to me, if you believe our research intentions are aligned and you are keen to collaborate on a project.
