- Drug Discovery Research: Led and managed the discovery portfolio of early discovery programs on complex human diseases such as metabolic and inflammatory disorders as well as oncology utilizing the small molecule and natural products formulations for their pre-clinical development while working with inter-disciplinary institutional and global teams in leading pharmaceutical companies during 2002-2017.
Current Interests: Non-alcoholic fatty liver disease
NAFLD is a slow-progressing disease with aberrant lipid metabolism, inflammation, oxidative stress, and fibrosis which has nearly 30 % global prevalence with no treatment options available to date. Current focus of my lab is to understand the pathophysiology and identify potential therapeutic options for the management of Non-alcoholic fatty liver disease(NAFLD) and associated comorbidities.
My lab has established in vitro and in vivo models to perform pre-clinical assesment of small chemical entities as well as natural product formulations to identify potential therapeutic options for the management of NAFLD.
Apart from conventional 2D models my lab has established multilineage 3D spheroid models mimicking the liver heterogeneity to test the anti-steatotic, anti-inflammatory and anti-fibrotic properties of test compounds.
Short-listed molecules as a result of this exercise are further evaluated for their pharmaco-kinetic analysis followed by screening in the in vivo models of NAFLD using mice fed with different types of carbohydrate and fat rich diets.
My lab also has a keen interest in understanding the role of different members of inflammasome family in progression of NAFLD and their correlation with different diets in animals and patients using metabolites and gene expression studies in different metabolic tissues.
Establishment of Liver Organoid Platform
To overcome the issues related to the translation of the in vitro findings into the in vivo set ups and later at the clinical stage, we need more realistic screening models. My lab has therefore established human liver organoids using healthy humans and NAFLD patients derived liver tissues as a platform to conduct drug discovery research and to understand the pathophysiology of NAFLD.
