Dr. Nibir Dhar

Chief Scientist, C5ISR Center NVESD, S&T Division

Short Biography

Dr. Dhar is the co-founder of iDISPLA initiative. He is a fellow of International Society for Optics and Photonics and Optical Society of America. He received the Office of the Secretary of Defense Medal for Exceptional Public Service in 2014, Henry Levinstein lifetime achievement Award in 2016 and NVESD Technical Excellence award in 2018. He received numerous R&D achievement awards, technology transition awards and industry awards for his technical contributions in the area of infrared science. He is a member of Optical Society of America, Eta Kappa Nu IEEE honor society and member of Golden Key honor society. He served as an adjunct professor and on PhD thesis review panels at the George Mason University, University of Maryland and University of Illinois at Chicago, and mentored ten Ph.D. students in various subjects through these activities. He has published numerous technical papers and book chapters. He is currently working on a book titled, "Uncooled Thermal Infrared Detectors - Science, Technology, Devices and Applications" to be published in Taylor & Francis, CRC Press. He also serves on the Old Dominion University Engineering Industrial Advisory Board. He is an executive board member for the Virginia Microelectronics Consortium.

Dr. Dhar received a master's degree and a Ph.D. in Electrical & Computer Engineering from the University of Maryland at College Park with a major in Microelectronics and a minor in Electro-physics. He received a BSEE degree in electrical and computer engineering from the George Mason University. For the past thirty years he has been leading the EOIR imaging technology for the US Armed Forces with a focus on Army and USSOCOM applications and product development. Dr. Dhar joined Night Vision and Electronic Sensors Directorate (NVESD) in April of 2014 as the Chief Scientist for science and technology to advance the R&D portfolio and technology maturation efforts. At NVESD, he is involved with the R&D programs in electronics, photonics, materials, detectors, FPAs, optics, processing, EOIR systems, AI/ML and applications in the imaging science and technology area. As part of his strategy to increase research and STEM portfolio at NVESD, Dr. Dhar initiated a new innovation platform called, "Innovative Discovery Science Platform" (iDISPLA) focusing on advanced R&D, education, workforce & outreach, collaboration and technology maturation. He is also driving innovation in the application of artificial intelligence in imaging, electronics and photonics technologies through the iDISPLA initiative.

Prior to joining NVESD, Dr. Dhar served for six-years as the program manager in the Microsystems Technology Office at the Defense Advanced Research Project Agency (DARPA). He had a large technology portfolio budget in excess of $290M addressing some of the key capability gaps in the Department of Defense imaging science area. His programs such as AWARE, LCTI-M, PIXNET etc. demonstrated some of the breakthrough solutions to the fundamental challenges in detectors, FPAs, electronics, imaging and photonics systems. His research involved new camera architectures to address wide field of view, large and very small form-factors, computational imaging and bio-inspired imaging designs for a variety of applications. These activities included heterogeneous materials integration, plasmonics, nanotechnology, photonics, sensors, wafer scale sensor manufacturing, novel optical designs, camera design, image processing and integrated circuits.

These research activities culminated into multi-front advances in the imaging science and related technologies and have set a new trend in the IR detectors and system design. His research addresses tactical wavelength bands from ultraviolet to 14 microns. At DARPA he developed various innovative technologies and transitioned several products to the US military and industry. One of his key program in uncooled FPA technology led to new manufacturing processes to reduce cost and enabled integration of thermal (microbolometer) cameras in smartphones and opened doors for innovation in small UAV and UGS applications. His other programs in cooled infrared systems also produced new capabilities for the warfighter and started infrared pixel scaling trend that led to 5 um pixels for 10 um radiation.

He made significant impact in nanotechnology and photonics and served on the review panel for the US initiative for American Institute for Manufacturing Integrated Photonics (AIM Photonics). His efforts added significant value to the Army and to the scientific community at large. Prior to DARPA he worked at Army Research Laboratory as the branch chief and team lead in EOIR technology. At ARL he served on panels for several Army institutes such as Institute for Soldier Nanotechnology, Institute for Collaborative Biotechnology and Micro-Autonomous Systems Technology.
