About Me

I am an ELLIS MSc. honours student in Artificial Intelligence at the University of Amsterdam (UvA). Prior to my graduate studies, I obtained my bachelor degrees in Artificial Intelligence (cum laude) and Information Science at the UvA. My interests include - but are not limited to - geometry, representation learning, generative models and AI4Science. Feel free to reach out to me if you want to talk about research!
