                                 PROFESSIONAL EXPERIENCE
Research Assistant, Aug. 2003 - Present
Broadband Access Wireless Communications Lab, Michigan State University, East Lansing, MI 48824

Spectrally efficient anti-jamming air interface design:
    Proposed a message-driven frequency hopping scheme by embedding part of the information stream
     into carrier frequency selection, leading to a multiple-fold increase in spectral efficiency.
    Accomplished an efficient secure communication interface design, with the OFDM framework to make
     full use of the radio spectrum and an AES-based subcarrier assignment algorithm to ensure collision-free

Bandwidth efficiency increase through blind channel estimation and signal detection:
   Designed a structured transmit delay scheme to enable independent information transmission at different
    antennas, resulting in drastically increased efficiency compared to space-time block coding.
   Developed a SOS-based blind channel estimation algorithm and signal detection approach to allow
    higher data rate transmission for MIMO systems without any pilot-aid.

PHY-layer security enhancement for DS-CDMA systems:
  Analyzed security weaknesses for IS-95 systems and innovated the AES-based secure scrambling,
   providing significantly improved information privacy with very limited complexity burden.
  Exploited the time diversity of chip-level interleaving to improve the robustness of CDMA systems in
   adverse environments and enhanced built-in security through the AES-based secure block interleaving.

R&D Engineer (Internship), Nov. 2006 - Apr. 2007
MediaBalance Inc., Wireless Embedded Behavior Mod., East Lansing, MI 48823

Adult Weight Loss project: participated in the development of a Bluetooth-based portable product used to
measure the amount of daily exercise aimed towards supporting behavior modification:
   Fulfilled reading and writing functionalities using C programming for data EEPROM memory of
    dsPIC30F3012 microcontroller.
   Designed a bandpass filter with the Direct Form II transposed structure for data stream collected by
    ADXL accelerator to remove out-of-band noise.
   Developed a mobile Java application using J2ME to communicate with the Bluegiga chip on the board
     through UART interfaces of dsPIC30F3012 over wireless links.

WATCH project: acted as a team leader responsible for refinement of a wireless embedded system with
LCD to realize instantaneous and consistent information exchange between clients and server:
  Analyzed problems, synthesized solutions, allocated tasks, documented software development process.
  Achieved customized UART interfaces and functions for parsing the incoming commands to
   communicate with the Bluegiga device controlled by dsPIC30F3014.
  Created a real-time timer, an animation and the company logo, and displayed them on the LCD along
   with the operation update.

Research Assistant, Jan. 2000 - Jun. 2003
Communication and Electronic System Lab, Univ. of Sci. & Tech. of China, Hefei, Anhui, China
   Designed an instructional software of digital image processing with friendly UI using Microsoft Visual
    C++ 6.0, including most of classic algorithms in image processing.
   Developed an instant messenger (a text-based chat system) used in LAN through Microsoft Visual C++
    6.0. Functions like user management, message forwarding and document transfer were realized.
   Took charge of the project supported by Microsoft Research Asia, Image Inpainting Based On Level
    Lines, as a team leader. Three inpainting algorithms based on level lines were developed to efficiently
    restore damaged texture of images and later extended to image compression.

Software Engineer, Jul. 2002 - Jun. 2003
