My collective experience in research, academic, industrial and administrative leadership totals over 33 years. Currently working as a Distinguished Member of Technical Staff (DMTS) at QuantumScape Corporation. My major role is to lead a team of scientists, engineers, and technicians for the development of ceramic solid electrolyte and production of ceramic separators through fast sintering process for lithium metal batteries.
Earlier, I worked as a Professor of Physics at Pondicherry University, India and as Director of the Department of Science, Technology & Environment (DSTE), Govt. of Puducherry, India. Also, I engaged as a Visiting Scientist at the University of Texas at Austin USA, Shizuoka University and Nagoya University Japan, as a Guest Researcher at the University of Kiel Germany, and as a postdoctoral fellow at National Tsinghua University (NTHU) Taiwan.
Our research focuses on the design, synthesis, and characterization of functional materials, particularly for practical applications in lithium metal batteries, emphasizing understanding their intimate structure-property interplay. My major contribution is the invention of garnet structured solid electrolyte Li7La3Zr2O12 (LLZO) [PCT/EP2008/005402 (2008), US Patent 8,658,317B2 (2014), PCT/JP2011/065489 (2011), US Patent 8,865,355B2 (2014), US Patent 9,450,271B2 (2016)] as electrolyte for an all-solid-state lithium battery. I have an exclusive experience of 18 years on garnet materials research and involved in organizing 4 World conferences on Garnets. Published more than 150 research papers in internationally reputed journals with citations of 11300 and had an opportunity to guide 17 research scholars in the Ph.D. program and mentor 8 post-doctoral fellows.
I was privileged to work with world-leading researchers; Prof. John B Goodenough (Nobel Laureate in Chemistry 2019, UT Austin, USA), Prof. Werner Weppner (Univ. of Kiel, Germany), and Prof. Robert Huggins (Univ. of Kiel, Germany/Stanford Univ. USA) in developing high energy density batteries and actively worked with industrial partners: Corning Inc USA, Applied Materials USA, Fisker Inc. USA and HBL Power Systems Hyderabad India, through consultancy projects and government sponsored projects tuning around 2 million USD to address some of the challenges in the realization of lithium metal battery technology for electric mobility and consumer electronics.
Currently serving as Editorial board member of the journal “Ionics” published by Springer, and President of the Energy Science Society of India (ESSI). Honored as a Fellow of the Royal Society of Chemistry (FRSC), Fellow of the Academy of Sciences Chennai (FASCh.) and a Research Award by UGC, India and Young Scientist by DST, Govt. of India. Also, I have undergone training on the "Leadership for Academicians Program (LeAP) in Higher Education" at the University of Cambridge UK a flagship scheme of MoE (then MHRD), Govt. of India.
