I am currently an AI Scientist at HHMI Janelia Research Campus, where I am part of the AI@HHMI initiative. I completed my PhD in Computer Science at Harvard University, where I was advised by Hanspeter Pfister. During my PhD, I was also working with Srini Turaga at HHMI Janelia as a visiting researcher and as a ML Fellow at E11.bio. I received my M. Sc. and B. Sc. degrees in Computer Science from TU Wien, Austria. I was born and raised in the beautiful town of Regensburg in Germany.

My research interests lie broadly in applied machine learning and data visualization, especially with applications in neuroscience. Specifically, I focus on building scalable interactive visual analysis tools and representation learning approaches to analyze the hidden architecture of the brain.
