Area of Research Interest:
Bioactive compounds for health and diseases,
Food based approach to prevent chronic diseases
Protein biochemistry and Bioinformatics
Goal of my research is to optimize the health profiles of food products and provide “Modern Evidence for Ancient Wisdom on Diet in prevention of diseases”.
(BIOACTIVE COMPOUNDS FOR HEALTH: Cancer and infectious diseases are the leading diseases posing a serious demographic and economic burden worldwide. Available drugs combat these diseases with strenuous side effects and need for a development of effective safe drugs. As Hippocrates (father of medicine) quoted “Let food be thy medicine and medicine be thy food” and Ayurveda told “Let food be your medicine”. Indian cuisine encompasses a wide variety of regional cuisines native to India with locally available spices, herbs, vegetables and fruits. This diet is having rich sources of bioactive compounds, lead molecules for safe drug discovery. Our laboratory uses animal, cell and in silico models to explore the role of dietary bioactive compounds in both the development and prevention of cancer and infectious diseases. In particular, we examine how dietary bioactive components alter molecular signaling pathways, omics study, identification of lead molecule and effective drug design by using bioinformatics tools. The long-term goal of my research is to optimize the health profiles of Indian food products and provide modern evidence for ancient wisdom on diet and disease.)
