Molecular Biology, Protein Engineering & Biotherapeutics.


My expertise in biology ranges from biotechnology to genetic manipulation of bacterial cells to acquire desired phenotypes, to genetic engineering of proteins, to transgenic animal models, to cell and tissue engineering. The current focus of my laboratory is to develop novel therapeutic proteins. We have been able to develop the biosimilar of G-CSF (Filgrastim). Additionally, we are also developing the PEGylated G-CSF biosimilar (Pegfilgrastim), which has longer half-life and is administered once per cycle of chemotherapy. Recently, my laboratory has also embarked upon development of advanced G-CSF molecules. We work on process development for efficient protein purification and characterization of this important therapeutic protein. Besides, G-CSF, we also strive to engineer novel and valuable cytokines, growth factors and antibodies. Given that a number of therapeutic proteins are imported, the creation of biosimilars and biobetters of many of the biotherapeutics is the need of the hour in India. We are also interested in development of animal models for various diseases and their deployment in analysis of efficacy of the lab-made therapeutics. Another interest of the laboratory is to decipher the role of vital organ microbiome in health and diseases.
