Bio Sketch

Ravi Shankar was born (1980) in Jaipur, India. He received his M.Sc. (2003) at the Mohanlal Sukhadia University Udaipur and his Ph.D. (2004-2009) in Medicinal Chemistry at the CSIR-Central Drug Research Institute (CDRI) under the supervision of Dr. Kanchan Hajela. He then joined Prof. Rohit Kolhatkar (2009-2011) group at University of Maryland, Baltimore as a Postdoctoral fellow and worked on development of peptide based drug delivery thereafter he moved to University of Illinois with same group. He continued his Postdoctoral carrier with distinguished Prof. C.K. Chu’s (2011-2013) at University of Georgia, USA to work for the anti-viral drug development of nucleoside as well as non-nucleoside analogues for HIV, HBV, HCV and influenza. In October 2013, he joined as a Scientist at CSIR-Indian Institute of Integrative Medicine (CSIR-IIIM), India where he established a medicinal chemistry research group focused on the design and synthesis of natural product analogues for identification of potent biological hit and development of target specific Drug Delivery Systems.

Education

Degree Subjects University Qualifying Year
Ph.D. Medicinal Chemistry Dr. Bhim Rao Ambedkar University (*C.D.R.I. Lucknow) 2010

Overview

Our group deals with development new methods towards construction of natural and pharmaceutically relevant compounds. Generation of focused library of natural product and their derivatives for identification bioactive lead molecules.

Our research group also involve development of polymeric systems to carry small molecular weight therapeutics at specific sites by passive targeting as well as active targeting. The prerequisite for such polymeric therapeutics is to release the drug at targeted sites with maximizes the drug release by pH or enzyme based degradation.
