namrata das, Ph.D.

Postdoctoral Research Fellow

Namrata Das completed her medical training in India and a Master's in public health from Missouri State University. Her previous clinical experience underscored the large gap in knowledge and treatment regimens of Alzheimer's disease due to multifactorial physiological changes in the brain, which led to her decision to enroll in the Cognition and Neuroscience PhD program at the University of Texas at Dallas, School of Brain and Behavioral Science. At UT Dallas, Dr. Das’s work focused on exploring the relationship between sleep, cognitive behavior, and neurometabolic changes in brain energy metabolism which she examined using 31 phosphorus magnetic resonance spectroscopy at 7-Tesla in cognitively normal adults, those with amnestic mild cognitive impairment or mild Alzheimer's disease. Currently, Dr. Das is a NIDA T32 postdoctoral research fellow in the Drug Abuse and Brain Imaging Training Program. Under the mentorship of Dr. Gruber, Dr. Das’s work at McLean will be focused on utilizing multimodal imaging techniques to improve our understanding of the neural correlates of drug abuse and its association with cognitive performance.
