EDUCATION

  • Ph.D.               University of Illinois at Urbana-Champaign, Urbana, Illinois
    Analytical Chemistry  GPA:3.95/4.00                                             June 2004        
    Thesis:     "Electrochemical Reduction of Dioxygen and Peroxide on Modified Metal Surfaces"
    Thesis Advisor: Professor Andrew A. Gewirth
     
  • B.S.                 Peking University, Beijing, P. R. China
    Chemistry                     GPA: 3.80/4.00                                            May 1999
    Thesis:     "The Properties of Emulsion"
    Thesis Advisor: Professor Hongcheng Gao
     
  • CBA (Certification of Business Administration)
    University of Illinois, Urbana, Illinois                                               May 2004

    • RESEARCH EXPERIENCE

          Ad Interim Assistant Professor, TAMU, Commerce Texas                09/2006- 

    • Study the mammalian cell activity using both experimental and simulation approaches.

          Postdoctoral Research, Dr. Allen J. Bard, University of Texas, Austin, Texas         07/2004 – 09/2006

  • Scanned and developed effective non-Pt catalyst for O2 reduction using Scanning Electrochemical Microscopy (SECM).
     
  • Explored the antimicrobial effect of Ag ion and nanoparticle on mammalian cells and bacteria using cell imaging methods.

  • Studied mammalian cell activity and its response to external stimuli through monitoring electrochemically active species (extracellular and intracellular) using both experimental and theoretical approaches.

  • Set up a biological cell culture facility and made it a routine performance in the lab.

    •         Doctoral Research, University of Illinois, Urbana, Illinois 1999-07/2004

  • Studied peroxide and dioxygen electroreduction on foreign-metal modified Au and Pt surfaces using electrochemical methods, surface sensitive spectroscopies and density functional theory (DFT) simulations. Considerable insight into these catalytic mechanisms resulted from this work.

  • Investigated the three different potential-dependent orientations of thiocyanate formed on Au electrode surfaces using surface specified spectroscopies. A unique inversed Stark Shift was observed and clarified with one of these orientations with the aid of computational simulations.

  • Explored the way in which the combination of polyethylene glycol (PEG) with chloride ions acts as an inhibitor in Cu deposition. The inhibition effect is found to correlate with the formation of a PEG-Cu-Cl helix complex on the growing Cu surface.

  • Examined the different behaviors of polyoxometalates on different surfaces with potential control.

  • Designed or developed instruments of SERS and surface XRD for in situ electrochemical characterization.

    •

          Undergraduate Research , Peking University, Beijing ,P.R.China 1998-1999            

  • Studied the chemical and physical properties (e.g. water content) of emulsions.
