About me

I am a postdoctoral researcher associated with the Advanced Interactive Technologies Lab and the Sensing, Interaction & Perception Lab at ETH Zurich. My research interests lie at the intersection of reinforcement learning, human-computer interaction, and cognitive psychology. I am working on modeling the closed-loop dynamics of human-computer interaction to create truly functional adaptive user interfaces.

I received my doctoral degree from ETH Zürich, advised by Professor Otmar Hilliges. I interned at Facebook Reality Labs with Hrvoje Benko (2018) and visited the User Interfaces group at Aalto University where I worked with Antti Oulasvirta (2017). Prior to my postdoc, I worked for the robotics startup Tinamu AG, a spin-off from ETH Zurich.

You can also find me on Google Scholar and ResearchGate.
