PROFILE:
Ajay Raghavan
Ajay Raghavan researches device fleet health management, diagnostics and prognostics, electromechanical systems, and sensors -- focusing on application areas such as energy storage devices and transportation infrastructure. He is the Principal Investigator on the SENSOR project under the ARPA-e AMPED program, where he is leading a multidisciplinary effort to develop fiber optic sensing-based battery management systems. His expertise includes modeling, dynamics, pattern recognition and signal processing algorithms, piezoelectric transducers, and wave propagation.
Prior to joining PARC, Ajay worked as Lead Algorithms Engineer at Metis Design Corporation, where he was involved in developing compact active sensor systems and algorithms for health monitoring of aerospace structures using guided-wave methods. He has also consulted for various companies and agencies such as Boeing, NASA, Air Force Research Laboratory, Goodrich, ATK, and Vought Aircraft.
Dr. Raghavan conducted his Ph.D. work on guided-wave structural health monitoring at the University of Michigan Ann Arbor, where he also obtained his Master's degree in Aerospace Engineering. He has a Bachelor's degree in Mechanical Engineering from the Indian Institute of Technology Bombay. Ajay has 8 pending patents; published two book chapters and 25+ papers in leading journals and conferences, and received the Best Paper award at the Prognostics and Health Management Society conference; and was awarded an NSF fellowship to attend the Pan American Advanced Study Institute on damage prognosis in Brazil.
In his spare time, Ajay enjoys sports (especially cricket!), the arts, working out, and hiking.
