Research Interests

My research interests are mainly in radio telescope design and integration test with custom instruments. I was joined in IAA for AMiBA (Array for Microwave Background Anisotropy) project and assigned for W-band receiver assemble and on site test. After AMiBA dedication in 2006, I pursued to engage the MMIC (Monolithic Microwave Integrated Circuit) technology for AMiBA LO module miniaturization to improve the system stability. Since 2011, I worked on SMA (Sub-Millimeter Array) project and cooperated with SAO colleagues to develop ultra-wide IF bandwidth (2-18GHz) receiver in microwave and sub-millimeter band (176 ~ 420GHz). In additional to SMA project, I also joined the GLT (Greenland telescope) project to expend my interests into VLBI (Very Long Baseline Interferometry) instrument development. Most VLBI instruments has very specific requirement in frequency range as well as the phase stability, and I am interesting to develop these instruments for future application.
