Peter H. Siegel has held appointments as Faculty Associate in Electrical Engineering and Senior Scientist in Biology at the California Institute of Technology, and Senior Research Scientist at the NASA Jet Propulsion Laboratory, both in Pasadena, California.  At JPL, he founded and led for 25 years, the Submillimeter Wave Advanced Technology (SWAT) team, a group of 20+ scientists and engineers developing THz technology for NASA’s near and long term space missions. This included delivering key components for four major satellite missions and leading more than 75 smaller R&D programs for NASA and the US department of defence. At Caltech, Dr. Siegel has been involved in new biological and medical applications of THz, especially low power effects on neurons and most recently, millimeter-wave monitoring of blood chemistry. Among many other functions, he served as founding Editor-in-Chief of the IEEE Transactions on Terahertz Science and Technology (2010-2015) and founder, and now the General Secretary, of the International Society of Infrared, Millimeter, and Terahertz Waves, the world’s largest society devoted exclusively to THz science and technology. He is also an IEEE Fellow, and has served as an IEEE Distinguished lecturer, vice-chair and chair of IEEE MTTS Committee 4 – THz Technology, and an ad-hoc member of the MTTS AdCom for more than 10 years. Dr. Siegel has published more than 300 articles on THz components and technology and has given more than 200 invited talks on this subject throughout his career of 40 years in THz. His current appointments include: CEO of THz Global, a small R&D company specializing in RF bio applications; Faculty Associate in Electrical Engineering at Caltech; and Senior Research Scientist Emeritus at the NASA Jet Propulsion Laboratory.
