Prof. Ramendra Pratap joined the Department of Chemistry as Assistant Professor in 2010 and promoted to full prof in 2022. He obtained his Ph.D. degree from Central Drug Research Institute, Lucknow in 2007 under the supervision of Late Dr. Vishnu Ji Ram. He worked as post-doctoral researcher for two years (2007-2009) in the City College, City University of New York. Then he received the prestigious Alexander von Humboldt fellowship and worked for one year (2009-2010) in the Universitat des Saarlandes, Saarbrucken, Germany with Prof. Uli Kazmaier. He has published more than 100 research papers in peer reviewed international journals. He also authored 2 books of heterocyclic Chemistry and 2 reference books on the chemistry of fused and isolated pyrans. He also authored 2 book chapters in different books. He also received funding from different agencies such as DST, SERB, CSIR, ICMR etc. His current research is focused on the synthesis of various carbocycles and heterocycles, metal catalyzed C-C and C-N bond formation reactions, nucleoside modification reaction and medicinal chemistry. Recently, he visited Department of Chemistry, Kyoto University, Kyoto, Japan as visiting professor under JSPS invitation fellowship. He is also working as consultant in Arontier Co., South Korea for the development of new biologically potent molecules.
