Research Scientist

Dr. Bharati Debnath obtained her B.Sc. and M.Sc. in chemistry from University of Kalyani. She received her Ph.D. (2019) in Chemical Sciences from IISER Kolkata under supervision of Prof. Sayan Bhattacharyya. Her doctoral studies were based on synthesis of transition metal-oxide nanomaterials with different morphology and their low-temperature magnetic interactions and catalytic properties. During Ph.D. she worked on electrocatalytic water splitting. After completing her Ph.D. she joined IIT Ropar as a postdoctoral research fellow in the group of Dr. C. M. Nagaraja where she focused on nanomaterial synthesis and studied their photocatalytic H2 generation. Then she joined Prof. Satishchandra Ogale’s group as a postdoctoral research fellow at IISER Pune. There she worked on photocatalytic CO2 reduction and photocatalytic N2 reduction. Also she contributed in the area of high Nickel rich cathode materials for Li ion batteries. Bharati guided several masters’ students and summer interns during her Ph.D. and Postdoctoral tenure. In 2021 she joined Research Institute of Sustainable Energy (RISE) under TCG CREST as a research scientist. Dr. Debnath’s research interests are in the area of development of catalysts with controlled size and shape and their application in the area of green fuel production.
