Dr. Leon-Salas received the B.Sc. degree in electronic engineering from the Universidad Nacional de San Agustín, Arequipa, Peru, and the M.Sc. and Ph.D. degrees in electrical engineering from the University of Nebraska-Lincoln (UNL) in 2001 and 2006, respectively. Currently he is an Associate Professor in the School of Engineering Technology at Purdue University. His research interests are in the areas of CMOS image sensors, solar energy harvesting, optical communications and optical devices. Dr. Leon-Salas directs the tinyLab which is dedicated to the integration of electronic circuits with optical devices. He has published over 80 journal and conference papers in these areas. Dr. Leon-Salas teaches classes in digital signal processing and digital circuit design. In 1996 he received the first place in the national undergraduate project competition in INTERCON for his project Neuro-Fuzzy Controller. He received the Best Doctoral Dissertation award from the College of Engineering at UNL in 2007, the CAREER award from the National Science Foundation in 2011, the Outstanding Faculty in Discovery award from the School of Engineering Technology at Purdue University in 2014 and the best runner up live demo award in the 2018 IEEE ISCAS conference. He has served as a reviewer for several journals, as a proposal reviewer for the National Science Foundation and is a regular session chair and Review Committee Member (RCM) for the IEEE ISCAS conference. He is the Secretary elect for the IEEE Sensory Systems Technical Committee.
