Research Interests
Our research interests are broadly based on neurochemical biology, neurophysiology and molecular medicine. Key areas in our lab are:
Ø Function and regulation of metals and metalloenzymes in nervous system. Defects in biological regulation of metal ions are linked to neurodegenerative diseases like Alzheimer ’s disease and Parkinson’s diesease. The focus of our study is on elucidating the role and regulation of metal ions and metalloenzymes in nervous system.
Ø Targeting and probing lymphatic drainage pathway in central nervous system using novel strategies in chemical biology. Lymphatic drainage is a holistic approach to move toxins and other products away from healthy cells, but the lymphatic drainage pathway in central nervous system has not been well described. We explore novel chemical biological tools aimed at tracking the pathway and identifying modulator in this process.
