Research

Jemmis is engaged in the study of structure and reactivity of molecules, clusters and solids using theoretical methods. A constant attempt is made by his group to find common threads between problems of different areas, viz. between organic and organometallic chemistry; amongst the chemistry of various main group elements; between polymorphs of elements and their compounds; etc. His research group not only gets numbers as an answer to a problem, but also tries to find out why the numbers turn out the way they do, based on overlap of orbitals, perturbation theory and symmetry, and devise transferable models. Significant results have been obtained in understanding the reactions of transition metal

Just as the basic tenets of the structural chemistry of carbon has stood the test of time, and led to major developments in carbon, the edifice of the structural chemistry expounded by Jemmis has already begun to do so for boron. Several of his predictions have been proved experimentally. He has mentored 20 PhD students and several postdoctoral and students and research associates, and published about 200 research articles.
