• Objective:
  To obtain a fulltime research or postdoctoral position
• Research Interests:
  1.    Modeling and simulation of micro/nano mechanics of materials
  2.   Deformation, adhesion and size-effects in thin films and cells
  3.   Mechanism of adhesive contact and fundamentals of tribology
• Education Background:
  09/2002-07/2007, Ph.D., Major: Engineering Mechanics
  University of Science and Technology of China (USTC)
  09/1998-07/2002, B.S., Major: Theoretical and Applied Mechanics
        University of Science and Technology of China (USTC)
• Research Project:
  10/2004-10/2006: Graduate Innovation Fund of USTC (KD2004036, Surface Effect on the Microcontact Mechanical Behavior)
• Experiences:
  Research assistant of Professor Jilin Yu
  05/2004-Present: A theoretical study on the micro/nano contact mechanics
  Through the department and school selections, my research project achieved the support of the 1st Graduate Innovation Fund of USTC. The continuum mechanics models on the adhesive contact between elastic spheres are extended to those of arbitrary axisymmetric elastic objects with an arbitrary surface adhesive interaction. The main finding is a supplementary relation for the Maugis-Dugdale model to match the exact model.
  07/2003-05/2004: A numerical study on the dynamic of 2D cellular structures
  This work is supported by the National Science Foundation of China (NSFC). The dynamic behavior of 2D cellular structures was studied by a finite element simulation using ABAQUS/Explicit code. The influences of cell irregularity and impact velocity on the deformation mode and the plateau stress were investigated.
  11/2002-07/2003: A theoretical study on the progressive buckling of tubes
  The deformation modes of the progressive crushing of circular tubes attracted my interests. The so-called optimal eccentricity factor 0.65 in the literature was concluded to be incorrect. The deduction was corrected and the postulate was revised.
  Research assistant of Professor Xiezhen Yin
  10/2001-07/2002: An experimental study on the unsteady motion of 2D foil
  I completed this work as my B.S. degree thesis. Using the hydrogen bubble method, the reverse-Karman vortex street in the wake flow was visualized and quantitatively measured.
