'''Eluvathingal Devassy Jemmis''' or '''E. D. Jemmis''' (born 31 October 1951) is a Professor of theoretical chemistry at the [[Indian Institute of Science]], Bangalore, India. He was the founding Director of [[Indian Institute of Science Education and Research]], Thiruvananthapuram [[Indian Institute of Science Education and Research, Thiruvananthapuram|(IISER-TVM)]]. His primary area of research is [[Quantum chemistry|applied theoretical chemistry]] with emphasis on structure, bonding and reactivity, across the periodic table of the elements.

==Education==
Eluvathingal D Jemmis, after obtaining his BSc from University College, Thiruvananthapuram and [[St. Thomas College, Thrissur]] and MSc from [[IIT Kanpur]], joined [[Princeton University]] (1973) under the supervision of Profs [[Paul von Rague Schleyer]] and [[John Pople]] (1998 Nobel Laureate). Moving along with his supervisors Jemmis spent one semester at the [[University of Munich]] and four semesters at the University of Erlangen-Nuernberg. He was awarded the PhD degree (1978) from Princeton. After a two-year post-doctoral work at [[Cornell University]] with Professor [[Roald Hoffmann]] (1981 Nobel Laureate), he joined the School of Chemistry, [[University of Hyderabad]] (1980) rising to the rank of Professor (1990) and Dean (2002). Jemmis was a Visiting Fellow at the [[Australian National University]], Canberra (1991) and a Visiting Professor at the Centre for Computational Quantum Chemistry of the University of Georgia, Athens (2000). Dr. Jemmis is an honorary Professor at [[JNCASR]] and Adjunct Professor at ICTS-TIFR. In 2005 he accepted an invitation from the [[Indian Institute of Science]] (IISc), Bangalore and joined the Department of Inorganic and Physical Chemistry. In 2008 Dr. Jemmis moved again, this time on a five-year deputation, accepting the responsibility to start the [[Indian Institute of Science Education and Research, Thiruvananthapuram]].

==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 [[organometallic]]s, week [[hydrogen bond|H-bond]],<ref>{{cite journal|title=Red-, Blue-, or No-Shift in Hydrogen Bonds: A Unified Explanation|last=Jorly|first=J.|author2=Jemmis E.
