Professional Biography

Raj Madhavan is a research staff member with the Computational Sciences and Engineering Division of the Oak Ridge National Laboratory and a guest researcher with the Intelligent Systems Division of the National Institute of Standards and Technology. He received a Bachelor of Engineering degree (Electrical and Electronics) from the College of Engineering, Anna University, India, a Master of Engineering (Research) degree (Control and Robotics) from the Australian National University, and a Ph.D. (Field Robotics) from the University of Sydney, Australia.

Over the last decade, he has contributed to various topics in field robotics, systems and control theory. His current research interests include autonomous vehicle navigation in complex unstructured environments, performance metrics for intelligent systems, and urban search and rescue robotics. He has published over 100 papers in refereed journals, book chapters, conference proceedings, technical reports and has recently completed editing a book (with E. Messina and J. Albus): "Intelligent Vehicle Systems: A 4D/RCS Approach".

Dr. Madhavan serves as the Program Chair for the Performance Metrics and Intelligent Systems (PerMIS) Workshop (2006-), as an associate editor of IEEE Robotics and Automation Society's Conference Editorial Board, and on the International Journal of Tomography & Statistics' Editorial Board. He is an elected eminent Engineer of the Tau Beta Pi University of Maryland Chapter, a full member of the scientific research society, Sigma Xi, the Washington Academy of Sciences, a senior member of IEEE, and is the founding Chair of the IEEE Washington Section Robotics & Automation Society Chapter. He was the postgraduate winner of the 1998 IEEE Region 10 (Asia and the Pacific) student paper competition and the graduate division winner of the 1998 Society for Mining, Metallurgy and Exploration (SME) outstanding student paper contest. He has served on various program and organizing committees of international conferences and workshops and as an invited independent judge for robotics competitions, has given numerous invited presentations in research organizations in several countries and frequently serves as an invited chair of sessions in various robotics, automation and control conferences.
