Hey there, welcome to my website! I’m an AI Research Scientist at Meta working on modeling techniques for ultra-large-scale neural networks (recommendation systems).

Previously, I was PhD candidate in Machine Learning & Computer Vision at the ESAT-PSI lab advised by Prof. Tinne Tuytelaars. And even before that, I obtained my master from EPFL with a focus on machine learning where I also conducted research at the CVLab with Prof. Pascal Fua.

My primary research interests include self-supervised representation learning and multi-modal learning (vision-language).

Outside my PhD, I enjoy traveling and skiing.
