Dr. Venkatasubramanian (Ph.D. Rensselaer, New York, 1988; B.S. Indian Institute of Technology, Madras, India, 1983; Electrical Engineering) is dedicated to the innovation and advancement of several solid state energy conversion materials and device technologies as well as transitioning them to the commercial and defense industries. Dr. Venkatasubramanian is presently at the Johns Hopkins University, Applied Physics Lab as Team Leader for Energy and Thermal Management in the Research and Exploratory Development department. Dr. Venkatasubramanian is also the Co-Founder of Novus Energy Technologies, a spin-off company focused on energy technologies. Until April 2013, Dr. Venkatasubramanian was the Senior Research Director of the Center for Solid State Energetics at RTI International, where he directed innovative basic and applied research in thermoelectrics, photovoltaics, and optoelectronic materials and devices for solid state energy conversion applications. Dr. Venkatasubramanian is the Founder and was also the Chief Technology Officer of Nextreme Thermal Solutions, between 2004-2006, which is commercializing thin-film thermoelectric technology developed under his leadership with DARPA funding; Nextreme was acquired by Laird Technologies in Feb. 2013. Dr. Venkatasubramanian has over 115 peer-reviewed journal and conference publications, 15 issued patents, over 100 presentations in the area of thermoelectric materials and devices, photovoltaics, optoelectronics, and 5 book chapters and edited proceedings. Dr. Venkatasubramanian initiated and developed a research program focused on demonstrating the fundamental advantages of atomically engineered superlattices and other nanoscale materials; this research resulted in the first major breakthrough in the field of thermoelectrics in 40 years (Nature 2001, Nature Nanotechnology 2009), that led to hundreds of laboratories around the world working on other nanoscale thermoelectric materials. Dr. Venkatasubramanian has received two R&D 100 Awards in 2002 and 2010 for thermoelectric innovations, the Margaret Knox Excellence Award for research at RTI in 2002 and Rensselaer’s Allen B. Dumont Prize for research achievements. Dr. Venkatasubramanian was elected Fellow of the IEEE (2011) for contributions to nanoscale thermoelectrics for thermal management of electronics and energy harvesting and a Fellow of AAAS (2012) for seminal contributions to nansocale materials and devices for advanced thermoelectric devices. Dr. Venkatasubramanian has also contributed to advances in multi-junction GaAs-based photovoltaics, received a best paper award at the IEEE First World Conference on PV (1994), and his photovoltaics work has been recognized as key achievements by Department of Energy in 1995-97. Dr. Venkatasubramanian has organized several symposia and has edited proceedings in thermoelectrics, energy harvesting and nanoscale thermal transport for the American Physical Society, Materials Research Society, IEEE and other professional societies.
