I am a Visiting Assistant Professor in the Department of Mathematics at Texas A&M University. I am interested in combinatorics, structural graph theory, and their applications in algorithms and combinatorial optimization.
I obtained my PhD from the ACO program at Georgia Institute of Technology,
working with Xingxing Yu and previously with Robin Thomas.
I was partially supported by the NSERC Postgraduate Scholarship (PGS D).
I completed my Bachelor's and Master's degrees at University of Waterloo in Pure Mathematics and Combinatorics & Optimization.
