Zhihan Gao began Ph.D. studies in C&O in September 2011, after completing a Master's degree at Nankai University (China). He completed his Ph.D. in July 2015. His thesis, entitled Approximaton Algorithms for Path TSP, ATSP and TAP via Relaxations, was supervised by Professor Joseph Cheriyan.
Zhihan's research interests are in Approximation Algorithms, a topic that lies in the intersection of Combinatorial Optimization and Theoretical Computer Science. The major contributions in his outstanding Ph.D. thesis were the following:
The problems that Zhihan tackled in his Ph.D. thesis are fundamental in the field of combinatorial optimization. His results have been praised by numerous experts, and have already been taught to graduate students around the world. Zhihan's work was presented at top-tier theoretical computer science conferences APPROX and ICALP, and published in leading journals such as Mathematical Programming, SIAM Journal on Discrete Mathematics, Operations Research Letters, and Algorithmica.
Zhihan is presently doing a postdoctoral fellowship in the Department of Statistics and Actuarial Sciences at the University of Waterloo. He is working on applications of optimization in finance and insurance.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is co-ordinated within the Office of Indigenous Relations.
