Dr. Sayantan Paria is an Associate Professor in the Department of Chemistry at IIT Delhi. He earned his B.Sc. degree from Vidyasagar University in 2005 and his M.Sc. in Chemistry from the IIT Roorkee in 2007. In 2012, he completed his doctoral studies at the Indian Association for the Cultivation of Science, focusing on mimicking the functions of various nonheme enzymes.

In early 2013, Dr. Paria moved to Osaka University, Japan, where he conducted spectroscopic investigations and reactivity studies of metastable copper-oxygen intermediate species. He was awarded a prestigious JSPS fellowship in 2014. Subsequently, in May 2016, he joined ICIQ, Spain, as a postdoctoral fellow, where he worked on electrocatalytic water oxidation studies using molecular iron complexes.

Dr. Paria began his independent academic career at IIT Delhi in April 2017. His current research focuses on the spectroscopic investigation and proton-coupled electron transfer studies of high-valent 3d transition metal complexes. His group also explores electrocatalysis using molecular complexes, with applications in water oxidation, oxygen reduction, nitrite reduction, and related processes.
