About me

I recently started as an assistant professor at the NYU School of Medicine. I previously worked as a postdoctoral researcher at the NYU Center for Data Science with Prof. Kyunghyun Cho, Prof. Linda Moy and Prof. Sungheon G. Kim.

My main interests are unsupervised learning with neural networks, model compression, transfer learning and evaluation of machine learning models.

During my PhD studies at the University of Edinburgh I was supervised by Dr. Charles Sutton. My PhD was kindly sponsored by SICSA and EPSRC. Prior to studying towards a PhD in Machine Learning, I got my BSc and MSc degrees in Computer Science from the University of Warsaw. I worked on my MSc thesis as a visiting student at the University of Edinburgh under the supervision of Dr. Amos Storkey, my second supervisor was Prof. Andrzej Szałas. My thesis was on Machine Learning Markets. I also did industrial internships in Microsoft Research (Redmond, working with Rich Caruana and Abdel-rahman Mohamed), Amazon (Berlin, Ralf Herbrich's group), Microsoft (Bellevue) and J.P. Morgan (London).
