I am a post-doc with Kyunghyun Cho and Krzysztof Geras at New York University. I am also an advisor at Molecule.one (to start as a Chief Scientist in September). I do my best to contribute to the broad machine learning community. Currently, I am on the Scientific Committee of EEML, and serve as an area chair for NeurIPS 2020 and ICLR 2020. I received my PhD from Jagiellonian University co-supervised by Jacek Tabor and Amos Storkey (University of Edinburgh). During PhD, I spent two summers as a visiting researcher with Yoshua Bengio, and collaborated with Google Research in Zurich.

My email is staszek.jastrzebski (on gmail).
