PROFESSIONAL OBJECTIVE
A challenging position in Research and Development.
EDUCATION
University of Massachusetts – Amherst, Ph.D. Candidate (Physics) Summer 2009(expected)
Nanjing University, M.S. (Biophysics) June 2003
Nanjing University, B.S. (Biophysics) June 2000
EXPERIENCE
Stochastic simulations and modeling:
Developed a package of discrete element simulation programs (15,000 lines) as numerical tools
to study fast granular flow.
Illustrated the importance of external energy interface in determining the bulk property of a
boundary heated granular mixture through the break down of kinetic temperature equipartition
of a binary granular system by molecular dynamics simulation; devised a stochastic model and
a numerical model to further strengthen the conclusion.
Extracted statistics of power fluctuations in dilute granular systems and analyzed the
application of fluctuation theorem to such systems.
Simulated the distribution of rotational kinetic energy of a two dimensional granular gas and
achieved good comparison with experiments.
Built a simulated annealing program to optimize the searching of the ground energy state of
designed physical models.
Experimental design, image processing and data analysis:
Innovated new experimental technique to track individual granular particles in 3-dimension by
fast video imaging; investigated kinematics of a three dimensional granular system and
compared with kinetic theory.
Devised novel programs to identify particle collisions in a two dimensional granular system;
improved the locating precision of particles especially when particles are close to each other;
improved the study of short range correlations based on the identified collisions.
Developed a package of graphic user interface programs written in IDL (5,000 lines) for image
processing, particle tracking, result checking and data statistics.
Other professional activities:
Served on graduate admissions subcommittee of physics department of UMass.
Led group discussions for promoting team works and new idea generation.
