He holds the position of Reader at the Department of Chemistry. He has more than ten years of teaching and research experience in Synthetic Organic Chemistry. He has seven publications in peer review journals to his credit. He earned his PhD in 2006 from IIT Kharagpur. The PhD thesis work was based on Modified Hunsdiecker Reactions. His postdoctoral work at Technion, Israel Institute of Technology, Israel consisted of diastereo- and enantio-selective construction of all carbon quaternary stereocenters in acyclic systems. He is particularly interested in developing carbon-carbon and carbon-heteroatom bond forming processes, which efficiently create multiple stereocenters and their applications in the synthesis of valuable building blocks for organic chemistry, biologically important and structurally interesting organic compounds.
Now his research group is involved in studying the stereoselective claisen rearrangement reactions, stereo- and regio-selective hydroboration reactions, decarboxylative borylation reactions, synthesis of boron carboxylates and its application in decarboxylative 1,4-metallate shift reactions.

She is working on stereo selective Claisen rearrangement reaction towards construction of all carbon quaternary stereogenic centres in acyclic systems through asymmetric catalysis.
Stereoselective Claisen Rearrangement: The Claisen rearrangement is one the most powerful methods for the construction of carbon-carbon bonds.1 Since its discovery in 1912, the lack of a general process for the stereoselective synthesis of simple allyl vinyl ethers for the classical aliphatic Claisen rearrangement has frustrated synthetic chemists. Therefore, preparation of suitable allyl vinyl ethers from simple starting materials and subsequent Claisen Rearrangement with diastereo- & enantioselectivity has remained a formidable challenge. Furthermore, construction of an all cabon quaternary stereocenter in an acyclic system is not only a difficult task but a highly challenging one. This project focuses on the design of a novel domino process that consists of a metal catalyzed C-O bond coupling and a subsequent Claisen Rearrangement with diastereo- & enantioselectivity which leads to construction of two adjacent stereocenters along with the desired all carbon quaternary stereocenter.
Regio- and stereo-selective hydroboration of Ynamides: Vinylogous boron compounds are essential and versatile building blocks for a wide range of organic synthetic requirements and plays a vital role in the construction of complex molecular architechture. The most challenging part associated with this kind of selective functionalization via hydroboration is the control of the regioselectivity. We have developed a Cu(I)-catalyzed regio- and stereo-selective hydroboration of Ynamides with α-selectivity. High regiocontrol has been achieved by differentiating the size or the electronic characteristics of the acetylenic substituents and studying the synthetic applications of the vinyl boron species generated in this reaction.
