Dr. Adrian Tang has over 13 years of  commerical CMOS circuit design experience and is now in the sub-millimeter wave advanced technology group at NASA's Jet Propulsion Laboratory in Pasadena, California.  Adrian received his Ph.D. in electrical engineering from the University of California, Los Angeles in 2012. During his graduate studies, he developed CMOS mm-wave and THz circuits and systems for imaging, radar, and communication systems. He was the first to demonstrate reflective imaging in CMOS technology and the first to demonstrate sub-centimeter scale accuracy radar in silicon technology. During his postdoctoral studies he worked on developing 670 GHz compact radar systems for concealed weapons and explosives detection at stand-off. He is currently developing CMOS SoC technology for future THz instruments on NASA planetary science, earth science and astrophysics missions.
