Dr. Rama Venkatasubramanian is the Chief Technologist for Thermoelectrics, Team Leader for Energy & Thermal Management and a Principal Staff Scientist in the Research and Exploratory Development Department at the Johns Hopkins University Applied Physics Laboratory. Dr. Venkatasubramanian obtained his BS (1983) in Electrical Engineering from IIT Madras, India, and an MS (1985) and a PhD (1988) in Electrical Engineering from Rensselaer Polytechnic Institute, Troy, New York. He was a National Talent Search Scholar, Government of India (1977 – 1983) and was awarded the Allen B. Dumont Prize for outstanding academic achievement at Rensselaer (1989). Dr. Venkatasubramanian has pioneered the research and development of solid-state energy conversion materials and devices and has led multidisciplinary programs in the development of atomically engineered thin-film superlattices, controlled hierarchically engineered superlattice structures and nano-engineered bulk thermoelectric materials and devices for electronics and photonics thermal management, energy harvesting, and energy conversion. Dr. Venkatasubramanian has 120 peer-reviewed journal and conference publications, 20 issued US patents, over 100 presentations in the area of thermoelectrics, photovoltaics, optoelectronics, and five book chapters and edited proceedings. Dr. Venkatasubramanian was the Principal Investigator of Photovoltaic projects cited as key achievements by Dept. of Energy (1995, 1996, 1997) and has won the best Paper Award in III-V Photovoltaics, IEEE First World Conf. on Photovoltaics (1994). Dr. Venkatasubramanian has won two R&D 100 Awards (2002, 2010) for nano-engineered superlattice thermoelectric materials and microprocessor thermal management, was nominated for DARPA Sustained Excellence Award (2002) and recognized as the North Carolina Region IEEE Inventor of the Year Award (2003). Dr. Venkatasubramanian was selected as a Fellow of the IEEE for contributions to nanoscale thermoelectric materials, devices and electronics thermal management (2011) and a Fellow of the AAAS for seminal contributions to nanoscale thermoelectric materials development and novel device technologies (2012). Dr. Venkatasubramanian served as Editor of the IEEE Transactions on Electron Devices (2011-2020) with responsibility for Energy and Thermal Management topic areas. Dr. Venkatasubramanian has transitioned DARPA-funded thermoelectric technologies through a spin-off that he founded (Nextreme Thermal Solutions, which was acquired by Laird Thermal Systems in 2013) and through other collaborative partnerships with the US electronics and avionics industries. Dr. Venkatasubramanian has given over 25 invited presentations in universities worldwide as well as at various US Government agencies including USEPA, US DoE, US Air Force, US DTRA, US PTO and US Defense Science Research Council. Dr. Venkatasubramanian has published in Nature and Nature Nanotechnology and is in the top 0.5% of world-wide scientists in a recent 2020 ranking from Stanford (overall and in the area of Applied Physics) based on cited works in photovoltaics, nano-engineered superlattice thermoelectrics, thermal transport physics and device applications.
