Debobrata Sheet

Assistant Professor

B.Sc. Chemistry (Hons), Jadavpur University, India, (2005-2008).

M. Sc. Chemistry, Indian Institute of Technology Guwahati, India, (2008-2010).

Ph.D. Chemistry, Indian Association for the Cultivation of Science (IACS), Jadavpur University, India, (2010-2016).

Post-doctoral research. Institute of Condensed Matter and Nanosciences, Universite catholique de Louvain (IMCN/UCL), Belgium, 18 months BELSPO post doctoral Fellowship, (Feb, 2017- Aug, 2018).

I did my Ph.D from Indian Association for Cultivation of Science, under the supervision of Prof. Tapan Kanti Paine. My doctoral research title was, "Nonheme Iron Complexes for Bioinspired Oxidations with Dioxygen: Enhanced Reactivity through Immobilization on Functionalized Gold Nanoparticles". During this period I was engaged in developing functional models of Nonheme iron(II) enzymes for oxidation reactions. A part of my work also involved immobilization of these functional models on gold nanoparticles for catalytic selective oxidation reactions.

Then I moved to Belgium at the Universite catholique de Louvain (IMCN/UCL), for my post-doctoral research after receiving BELSPO postdoctoral Fellowship (18 months). Here I worked with Prof. Sophie Hermans and Prof. Olivier Riant. The work involved functionalization of carbon nanotubes for developing (organometallic/bio-inspired) catalysts with higher density of functional sites.
