Application of diverse biophysical techniques such as FTIR, NMR, CD, MALDI-TOF, ICP-MS, Fluorescence as well as Synchrotron based spectroscopic methods, for characterisation of medically important peptides, proteins, macromolecular interactions including protein-protein and protein-membrane interactions. Studies are also performed on cells, tissues and biofluids. Development of spectroscopic and bioinformatics tools for application in the fields of proteomics, metabolomics, disease diagnosis, screening and treatment. Structure-function studies of novel antimicrobial agents, based mainly on peptides and proteins, to counter antibiotic resistance. Role of metals in health and disease through analysis of metals in the environment, diet and the human body. Understanding the complex relationship between diet, exposure to pollutants, nutrition, life-style, ethnicity and health through human biomonitoring studies. Improving human health and the environment through development of novel, environmental friendly, strategies for removal of toxic contaminants from water and the food-chain. Studies of migrant health with particular focus on the relationship between health and practices such as betel quid chewing, geophagy.
