Assistant Professor

Dr. Anantharamaiah P N was born in Tumkur, India, in 1986. He received the M.Sc. degree in Analytical Chemistry from the Bangalore University – Bangalore, India, in 2009 and Ph.D. degree in Chemical Sciences from CSIR-National Chemical Laboratory — Pune, affiliated to Academy of Scientific and Innovative research — Delhi, India in 2017. Before joining CSIR- NCL, He worked as a chemistry teacher in Shree Swaminarayan International School, Bangalore, India, from July 2009 to March 2011. Soon after his doctoral program, he joined the Department of Chemistry, M.S. Ramaiah University of Applied Sciences, Bangalore, India in July 2017 as assistant professor. His current research interests include photocatalysis, electro catalysis, magneto strictive smart materials, gas sensors, designing magnetic based Nano catalysts to drive various organic reactions, nanomaterials and environmental remediation. He has published several research articles in international peer-reviewed journals. He is the Principal Investigator of a project worth INR 38 lakhs, funded by SERB –DST, Union Government of India.
