Dr. Suman Kr Dey is an Assistant Professor of Chemistry at the Centre for Distance and Online Education (CDOE), Vidyasagar University, West Bengal, India. His research lies at the interface of inorganic chemistry, bioinorganic modeling, and sustainable catalysis, with a focus on transition-metal complexes for small-molecule activation, oxygen and water activation chemistry, and biomimetic catalytic systems. Dr. Dey obtained his Ph.D. from the Indian Institute of Science Education and Research (IISER) Kolkata, where his doctoral work explored dioxygen activation and magnetostructural correlations in metal complexes of redox non-innocent ligands. He subsequently pursued postdoctoral research at SUNY Buffalo (USA) on photochemical water splitting using organometallic manganese complexes, and at IIT Kharagpur on water splitting with earth-abundant transition-metal systems. His research career also includes enzymatic modeling studies and international academic exposure at the University of Göttingen, Germany. His expertise spans inorganic and organometallic synthesis, catalysis involving oxygen activation and C–C bond transformations, hydrogen evolution, enzyme modeling (catechol oxidase systems), single-crystal X-ray crystallography, electrochemistry, magnetism, and advanced spectroscopic techniques. He has authored numerous peer-reviewed research articles in reputed international journals including Inorganic Chemistry, Dalton Transactions, Coordination Chemistry Reviews, ChemCatChem, and Journal of the American Chemical Society. CV_Dr. Suman Kr Dey_2025 A recipient of CSIR JRF and SRF fellowships and international postdoctoral funding, Dr. Dey is committed to developing bio-inspired and environmentally sustainable catalytic systems. Beyond research, he contributes to science communication and has also published a Bengali poetry collection, reflecting his creative engagement beyond the laboratory.

My research focuses on the activation and transformation of small, inert molecules using innovative coordination chemistry and biomimetic strategies. Small molecules such as CO2, N2, H2, O2, and CH4 are abundant yet chemically stable, making their controlled conversion one of the central challenges in modern chemistry. I am interested in designing functional metal complexes and catalytic systems that can selectively bind, activate, and convert these molecules into value-added chemicals under mild and sustainable conditions. A key aspect of my work involves understanding structure–reactivity relationships in metal–ligand frameworks, where electronic tuning, secondary coordination sphere effects, and cooperative interactions play crucial roles in bond activation. Inspired by metalloenzymes such as carbonic anhydrase and nitrogenase, I explore biomimetic approaches to develop efficient catalysts for processes related to CO2 utilization, green fuel generation, and environmentally relevant transformations. Beyond synthesis, my research integrates mechanistic studies, spectroscopic characterization, and theoretical insights to uncover how small molecule binding and activation occur at the molecular level. The broader goal is to contribute to sustainable chemistry, bridging fundamental inorganic chemistry with applications in energy, catalysis, and environmental remediation.
