About me

I am interested in Theoretical Computer Science in general and Graph Algorithms in particular. I am associated with Umass Theory Group. Before coming to Umass, I was a PIMS postdoc at the Compter Science Department, University of Victoria, hosted by Valerie King. I received a Ph.D. in Computer Science from Oregon State University. I am fortunate enough to have Cora Borradaile as my advisor. Long time ago, I got a B.S. degree in Computer Science (honors program) from Hanoi University of Science and Technology.

My research has been generously supported by an NSF small grant (CCF-2121952), an NSF CAREER Award (CCF-2237288) and a Google Research Scholar Award.


My technical blog Rambling on Graphs is up.


Check out our FOCS 2022 workshop “Advances on Metric Embeddings” I co-organize with Arnold Filtser.
