I am an assistant
professor at Department of Mathematics
of Texas A&M University. Before joining
Texas A&M, I was an instructor at Department
of Mathematics of Princeton
University. I received my Ph.D. degree in the Algorithms, Combinatorics, and Optimization
(ACO) program at School of
Mathematics of Georgia Institute of
Technology under the supervision of Robin Thomas. The title of my
thesis is Graph
Structures and Well-quasi-ordering. Before I went to Georgia Tech, I got my
B.S and M.S. degree from Department of
Mathematics at National Taiwan University.
My research is
partially supported by NSF under grant No. DMS-1929851 and DMS-1954054.
