I am a fourth year Ph.D candidate in the Cheriton School of Computer Science at the University of Waterloo.

I am interested in the theory and practice of machine learning. My thesis is focussed on developing and improving the theoretical foundations of clustering.

I am fortunate to be advised by Prof. Shai Ben-David. A consequence of this is that my research statement closely matches his.


Research motivation

When we discuss with some practioners as to why they chose a particular clustering algorithm, we often get the following responses. "Everyone uses it". OR "It has a nice python/matlab/(pick your favorite language) implementation". OR "Runs fast".

My research aims to address these issues by developing a principled way of choosing clustering algorithms. When is clustering easy? On what datasets should a particular be used? How should we incorporate human expertise into the clustering problem? We provide answers to such questions.
