About me


I am a Ph.D candidate in mathematics at Stanford University. I am a student of Professor Jun Li and expect to graduate in June 2010.


My research is on enumerative geometry, especially on counting nodal curves on algebraic surfaces. In my thesis I prove Goettsche's conjecture which says the number of nodal curves is given by a universal polynomials of four topological numbers. I'm also interested in Gromov-Witten theory, moduli spaces and algebraic cobordism.


  • B.S., Math, National Taiwan University, 2004.
  • Ph.D., Math, Stanford University (expected)


I'm currently a TA for Math 51 ACE. Here are the worksheets for my session.

Old teaching notes (some with brief answers):

Math 42 ACE (Winter 2009)

Math 41 ACE (Fall 2009)

Math 42

I like to play basketball, softball and listen to classical music.
