Biography: 

Dr. Neeraj Kumar, a computational scientist, has extensive research experience in computational chemistry, biophysics, drug discovery, structural and molecular biology, bio/cheminformatics, multi-omics data analysis, metabolic network, molecular modeling and simulation of complex biological systems. His graduate research was directed toward the molecular-level understanding of Vitamin B12 mediated enzymatic reactions and structure-based drug design using machine learning. Currently, his research interests are focused on developing mathematical and artificial intelligence (AI)/machine learning (ML) tools to solve challenging systems and synthetic biology problems at a fundamental level using basic principles of statistical physics/chemistry including chemical properties and accurate data computed from first principles approximation. This includes developing an AI-based small molecule design (both ligand and structure-based) for biomedical applications.
