Niki Kilbertus

My mission is to build socially beneficial, robust, and theoretically substantiated machine learning systems.

I am a PhD student in the Cambridge-Tübingen program (prospective graduation in 2020), where I am co-supervised by Bernhard Schölkopf and Carl Rasmussen. My advisor is Adrian Weller.

I am a member of Pembroke College, funded by the Cambridge-Tübingen PhD fellowship with generous donations from Microsoft.

During my PhD I spent time at Deepmind and Amazon.

My background is in Physics and Mathematics. I was fortunate to spend time at Harvard, working with Paul Chesler and Wilke van der Schee, as well as at Stanford, working with William East and Tom Abel.
