Thomas Poonnen was born in the late seventies in Kerala, India. He belongs to the Palampadom family, an ancient Christian family from India. He is the only child of Mrs. Sara Padmini and Mr. Thomas Palampadom. He is married to Breeta Erali Elbi, and they have a daughter, Nikita. He resides with his family at the CasaBreeta [+] in Greater Los Angeles, California, USA.
He has a Doctor of Philosophy (Ph.D.) degree in Electrical Engineering from the State University of New York at Buffalo, USA, a Master of Science (M.S.) degree in Electrical Engineering from the State University of New York at Buffalo, USA, and a Bachelor of Technology (B.Tech.) degree in Electrical and Electronics Engineering from the University of Kerala, India.
Dr. Poonnen has more than two decades of progressive experience in integrated circuit (IC) design, with expertise in digital image sensor design (ultraviolet / visible / infrared). He has been the technical lead for several CMOS image sensor (CIS) and readout integrated circuit (ROIC) products from conception to productization. He has also served as the Principal Investigator / Key Person on multiple research grants (DOW, NASA). He is presently the Director of Engineering at Senseeker, where he oversees the design and development of digital ROICs for defense and commercial infrared imaging applications. Prior to joining Senseeker, Dr. Poonnen was responsible for the design and development of digital CISs for cinematographic, industrial and scientific imaging applications at Panavision.
He also has several patents and technical publications to his credit. He is a Senior Member of the IEEE, and a Member of the SPIE, the ASME and the PMI.
