WORKING EXPERIENCE

The University of Texas at San Antonio, San Antonio, Texas

Research Assistant                                                      August 2010—December 2014

  • Assisted my advisor to do research related to how we can use Virtual Reality technology to do physical rehabilitation and exercises more effectively for people with mobility impairments. Used GoblinXNA (C#), Unity3D (C# and Javascript) to design and build 4 different Virtual Reality environments integrated with an eight-camera NaturalPoint motion tracking system, WiiMote, WiiFit balance board or Kinect. Used Google SketchUp to create simple 3D models. Conducted 4 usability tests with over 130 total users, half of which are mobility impaired persons. Used SPSS for all of the data analysis.
  • Mentored 9 students for their research projects. Taught them how to develop virtual environments using the equipment in the lab, helped them design and conduct 6 studies, as well as reviewed and edited their papers.
  • Lead a group of 5 students developing a “virtual MS walk San Antonio” project, which is a networked multiplayer walking environment for National MS Society Office in San Antonio. Set up timelines, milestones; organizing weekly meetings; and communicated with the officers from National MS Society Office. The project will be used in Walk MS: San Antonio on March 1st, 2014.
  • The research projects information could be found in my homepage.

The University of Texas at San Antonio, San Antonio, Texas

Teaching Assistant:                                                    August 2009—August 2010

  • Lead discussion of Advanced Programming with over 50 undergraduate students. Taught the students how to use vi to write codes under Linux, and how to debug the codes for the first two lessons. Made some sample codes to help students understand the concepts better based on each class and homework

University of Texas-Pan American, Edinburg, Texas

Teaching Assistant                                                      August 2007—July 2009

  • Advanced Network and Computer Architecture courses grader (Graduate level) in Computer Science

Jiangxi Tomorrow High Technology Co., LTD in Nanchang, Jiangxi Province, P.R.China.

Software Engineer                                                       June 2006—June 2007

  • Designed and built website and Office Automation Management System for the Association of Certified Public Accountants in Jiangxi Province (JAVA + Weblogic + Oracle)
