Work Experience
Metrologist Jan. 2010-present
College of Optical Sciences, University of Arizona, Tucson, AZ
• Work on the stitching software development for interferometric measurements

Graduate Research Associate/Assistant Aug. 2004-Dec .2009
College of Optical Sciences, University of Arizona, Tucson, AZ
• Designed the infrared and visible null correctors for the 4.3 m Discovery Channel Telescope (DCT) primary mirror, performed the tolerance analysis of these null correctors and helped assemble them
• Designed the computer-generated holograms (CGH) for the DCT primary mirror to calibrate both the infrared and visible null correctors
• Tested the DCT primary mirror with a laser tracker, an infrared interferometer, and a visible interferometer from the grinding phase to the figuring phase
• Performed accurate and low-noise measurements using interferometers for several projects
• Measured the phase MTF of an infrared interferometer and applied a Wiener filter to retrieve the middle spatial frequency information attenuated by the interferometer
• Studied the intrinsic errors in interferometric measurements, including the measurement noise, geometric errors and errors due to diffraction effects
• Studied the limitations in interferometer calibration using the random ball test
• Developed a smoothing-filter method to reduce the total errors introduced in map registration and subtraction
• Developed a methodology for optimizing the CGH to minimize its sensitivity to fabrication errors while maintain a good diffraction efficiency

Graduate Research Assistant Oct. 2001-Feb. 2004
State Key Laboratory of Modern Optical Instrumentation, Zhejiang University, Hangzhou, China
