Research

My research interest is scientific computing, especially semidefinite programming, optimization, and geometric computing.

Minisymposium Organization

• Stephen Vavasis and I are organizing a minisymposium at the Tenth SIAM Conference on Geometric Design & Computing, which will be held at San Antonio, Texas, November 4-8, 2007.  Link to the list of speakers and the abstracts of their talks.
   

Conference Presentation

• ``Fully sparse semidefinite programming using automatic differentiation", ICCOPT II, Hamilton, Ontario, Canada, August 13-16, 2007
• ``Condition-Number Analysis of An Algorithm for Finding All Polynomial Roots", SIAM conference on geometric design & computing, Phoenix-Mesa, October 31, 2005
• ``A Primal-dual Potential Reduction Method for Semidefinite Programs with Sparse Data", invited conference paper, INFORMS annual meeting, Denver, October 2004

Internship

• Argonne National Laboratory, Argonne IL (Summer 2005)

        As a Givens Associate, I worked with Mihai Anitescu in assessing the feasibility of using the Metropolis process to compute the radial distribution of different types of systems of particles at equilibrium and to reconstruct such systems from the given distribution.  The simulation was implemented in both Matlab and C++.

Teaching Assistantship

I worked as a teaching assistant for a number of courses in computer science department at Cornell University. Specifically, I was involved in the following courses:

Summer 2004	CS 322: Introduction to Scientific Computation
Spring 2004	CS 322: Introduction to Scientific Computation
Fall 2003	CS 421: Numerical Analysis
Summer 2003	CS 322: Introduction to Scientific Computation
Spring 2003	CS 322: Introduction to Scientific Computation
Fall 2002	CS 99: Fundamental Programming Concepts
