About

I am a machine learning researcher living in Amsterdam. Previously I was a postdoc in Max Welling’s Philips group with the Amsterdam Machine Learning Lab (AMLAB) at the University of Amsterdam. I did my PhD at UCL in the Machine Vision Group with Gabriel J. Brostow and Dr. Clare Wilson FRCOphth. Before that I studied engineering at The University of Cambridge, and am a scholar of Sidney Sussex College.

My current research interests include equivariance and combinatorial optimization, while previously I have worked on uncertainty quantification, unsupervised representation learning, variational inference, normalizing flows, optimization, and medical imaging.

For the last two years I lectured a course in Bayesian Statistics for Machine Learning, and have been the lab manager for the Philips lab at the UvA. I am proud contributor to the UvA Inclusive AI Initiative, which seeks to promote diversity and inclusion in the academic AI world.
