About me:

I am a Ph.D. student in the Computer Science Department at Carnegie Mellon University, where I have the honor and pleasure of being advised by Ariel Procaccia (now at Harvard).

Most of the time, I think about computational social choice, i.e., I search for algorithms that reconcile differing preferences in a way that provably ensures good outcomes. Among other things, I am thinking about new paradigms of democracy, refugee resettlement, and kidney exchange.

Before coming to CMU, I earned my undergraduate degree at Saarland University in Saarbrücken, Germany. There, I was fortunate to work with Bernd Finkbeiner on reactive synthesis.

I enjoy getting to know new people and chatting about research. Whether you're a researcher, a student interested in research, a practitioner, or just curious, just schedule a virtual coffee chat!
