Ryan Kerekes currently leads the RF Communications and Intelligent Systems research group at ORNL, where he has been a staff member since 2009. Prior to joining ORNL in 2007 as a postdoc, he received his B.S degree in Computer Engineering from the University of Tennessee, Knoxville, in 2003, and the M.S. and Ph.D. degrees in Electrical and Computer Engineering from Carnegie Mellon University in 2005 and 2007, respectively. His research interests include signal processing and machine learning, computer vision, pattern recognition, biometrics, and systems integration for national and global security applications. Dr. Kerekes has held a Principal Investigator role on numerous ORNL research projects in the biomedical, nuclear nonproliferation, and intelligence areas. In 2011, his team received the UT-Battelle award in Engineering R&D to recognize the development of a portable roadside radiation portal monitor. His current role is primarily in technical management and direction of R&D projects in signal and image analysis, with a focus on developing mathematical transformations for machine learning-based signal detection and characterization. Dr. Kerekes has authored or co-authored over 40 peer-reviewed publications.
