Our research is an interdisciplinary with an interface of chemistry and biology, emphasizes on lipid mediated gene therapy. Primary goal of our lab is to translate the concept of gene therapy to a clinically viable application. To this end, we are developing a library of lipids that can deliver nucleic acids efficiently both in vitro and in vivo. We are also focusing on understanding the mechanisms involved in lipid mediated transfections to overcome the major clinical limitations such as poor nucleic acid delivery efficiencies and cytotoxicities of nanocarriers. To increase the efficiency of the nanocarrier system, we are developing intrinsically active lipids for nucleic acids and drugs to enhance their efficacies in a synergistic manner. In the process, we aim to probe the mechanisms involved in lipofections. We are developing topical nucleic acid based therapeutics for autoimmune skin diseases such as psoriasis and vitiligo.

Lipids from vegetable oils

We also have collaboration with biologists to develop toolsets for efficient genome editing and reprograming of the cells.

With best regards!
