I am a first year Ph.D. student in the David R. Cheriton School of Computer Science at University of Waterloo, advised by Kimon Fountoulakis. I am a member of OpAL lab. I work on optimization and machine learning problems on graphs. Previously, I obtained a Master of Mathematics in the Department of Combinatorics & Optimization, where I worked with Ricardo Fukasawa and Laurent Poirrier.

Research interests

  • Computation and optimization on graphs and hypergraphs
  • Machine learning on graphs
  • Scientific computing
