Associate Professor
  • Ph.D., 2000, Pennsylvania State University
  • M.S., 1995, Beijing Institute of Polymer Technology
  • B.S., 1990, North China Institute of Electric Power

Areas of Research and Professional Interest
  • Laser Material Processing
    Objective: to deposit diamond-like carbon (DLC) thin films using pulsed laser deposition (PLD) technique and to model and simulate the deposition process.

  • Blast Wave Absorbing Structure
    Objective: to develop a novel blast wave absorbing structure that can be directly integrated into Army Future Combat Systems and to develop a blast load model for the optimization of the blast wave absorbing structure.

  • Diesel Engine Emissions Control
    Objective: to simulate the loading and regeneration of particulate matter and the thermal stress developed due to uneven heating, and the use of the numerical model as a design tool to meet the 2007 EPA Tier 2 emission standards.
