PERSONAL PROFILE

I see life as a movie, full of vivid characters and fascinating plots.

My role of an engineer is first to serve as a ‘generator’: I love to stimulate brain to produce new ideals and make them come true. My expanded role is an ‘amplifier’ which can inspire not only me but people around to recognize their own talents and arouse their passion to fulfill beautiful future by learning and sharing life experiences with others.

RESEARCH EXPERIENCE

• January 2007 – present University of Missouri, Columbia MO, U.S.A.

Graduate Researcher: Design, modeling and characterization of uncooled-infrared detector: a funded project by L3 Communications specialized in fabrication, test and characterization of SixGe1-xOy thin film as infrared sensitive material for microbolometer. Wire bonding, four point probe, low noise JFET, pre-amplifier and spectrum analyzer have been used to perform TCR, resistivity and noise measurement. Ellipsometry and FTIR have been used to measure thickness and optical properties. Behavior level simulation of microbolometer in optical, mechanical and thermal performance has been done by Coventorware.

• May 2007 – present University of Missouri Columbia MO, U.S.A.

Graduate Researcher: PDMS Micropost force sensor array for VSM Cell traction force analysis; a project specialized in design, modeling, fabrication and characterization of micromachined array of high density 3-dimensional microposts (100×100) made of flexible material (silicone elastomers) for measuring quantitatively the cellular traction force generated by vascular smooth muscle cell. Deep Reactive Ion Etching (DRIE) and atomic force microscrope (AFM) have been used to do fabrication and test. Matlab and Photoshop have been used to do phase contrast image processing.

• September 2000 – March 2003 Nanjing University of Sci.&Tech. Nanjing, China

Graduate Researcher: Multi-sensor signal processing using Data-Fusion. Two years research on using data-fusion theory and fuzzy theory for multi-sensor signal processing to increase the radar detecting possibility. Matlab has been used to perform scientific calculation of implementation performance.

• August 1999– November 2000 Nanjing University of Sci.&Tech. Nanjing, China

Undergraduate Researcher: Design a short-range distance survey system by using programmable time-delay device AD9501 and AVR 89C2051 single microprocessor. Assembly language and C have been used.

INDUSTRIAL EXPERIMENCE

• April 2005 ~ April 2006 Kungsbäck IT-Centrum Gävle, Sweden

Research Internship: Analysis and test of wireless broadcasting system (DVB-RCT). I was responsible of field test of hotspot with DVB-RCT protocols for wireless mobile broadband access: measuring noise ratio of OFDM wireless broadcasting signals; designing and implementing bi-direction testing client platform for evaluating transmission quality in different communication scenarios, different PHY and MAC configuration. Made comparison of WiMAX and DVB-RCT as wireless broadband access methods and finally gave evaluation of possibility of implement DVB-RCT in Sweden.

• June 2003 – May 2004 Play Co. Nanjing, China

Software Engineer: An Internet based Data Broadcasting Server software for a video-on-demand system. The subsystems participated in design and developments are: the scheduling subsystem, the downloading subsystem, and the publishing subsystem. ASP, Delphi, PowerBuilder and API on Windows operating system have been used.
