Dr. Viswas Purohit is our new Scientist of the Week! Learn more about his research and career goals in the interview that will be posted in a few days here at The Science and Engineering Cafe.
Who is Viswas Purohit?
Dr. Viswas Purohit is currently an independent research consultant at Oak Ridge, TN, USA, working on the development of portable atmospheric plasma- based sterilization units. He completed his Masters in Electronics from the University of Pune, India in 2001 and PhD in Plasma Physics from the University of Pune, India in 2007. He worked on his postdoc in material science, thin films and failure analysis of devices at the University of Nancy, France (2007-8) and the University of Rouen, France (2008-2011). Prior to moving to the US, he worked in the capacity of an Associate Professor in the Department of Plasma Physics at the Alliance University, Bangalore, India.
His research expertise is focused on applications of plasmas, particularly cold plasma for surface modifications, nanoparticle synthesis and Plasma Enhanced Chemical Vapor Deposition (PE-CVD). He has worked on nitridation of steels, the effect of ozone on polymer coatings on space vehicles and development of Electron Cyclotron Resonance Plasma reactors. His work focuses on the plasma material interaction and the physics behind particle interactions.
He has collaborated with several research groups in India, France, US and Singapore and has also mentored many masters and PhD students during his research career. He has more than 40 research publications, conferences and invited talks to his credit along with 1 patent and 2 provisional patents under his name. He has won the prestigious M.R. Bhiday award for the best industrial application in RMC. Recently, he won the national record for designing and developing the lightest autonomous robot in India (http://www.limcabookofrecords.in/recordDetail.aspx?rid=115). Dr. Purohit has also worked in projects like energy scavenging using ferrofluids and piezoelectric materials and low cost solar power generation.
