Dr. Niranjan's educational and professional stints since his earlier years as below.

Dr. Niranjan has focused his research on innovative approaches, identified that remodeling of subcellular organelles plays a critical role in the development of congestive heart failure due to myocardial infarction. His work has also resulted in a concept that heart dysfunction in diabetes is due to an imbalance between fatty acid and glucose utilization. The work demonstrated that stress-induced heart disease is due to the oxidation of catecholamines (stress hormones) and that the oxidized catecholamines are the most sensitive index of prognosis for heart failure.
