Akankasha Tiwari Goyal, MD


Originally from India, I moved to US to pursue my medical education. I completed a three-year residency in Internal Medicine at Jacobi Medical Center and then an academically oriented fellowship in Endocrinology, Diabetes and Metabolism at Albert Einstein College of Medicine and Montefiore Medical Center. At Einstein, I realized that my research interests lay in diabetes physiology, and began a series of metabolic physiology studies (“clamp” studies) in humans to examine mechanisms of insulin resistance via in-vivo tracer kinetics studies and adipose tissue dysfunction. My current work relates to the impact of Vitamin D repletion and resveratrol administration on insulin sensitivity and adipose tissue inflammation in obese, insulin-resistant individuals.

I joined the Division of Endocrinology at NYU Langone Medical Center in November 2016 and have setup Diabetes Biobank as part of the Center for Metabolic Health. This will allow us to have better understanding of the molecular mechanisms of diabetes, enable identification of individuals at highest risk, lead to risk stratification, and development of more targeted preventive measures. Clinically, I am also working to build a Type 1 diabetes clinic at the NYULMC and examine the pathophysiology of type 1 diabetes, its complications and hypoglycemia unawareness.

Andrew Parziale, MD

Research Fellow, 2017-2018

My focus since medical school has been on clinical medicine -- methods to enhance the quality of care delivered to patients, and patient education. Within endocrinology, my interest is in obesity/weight management which lends itself to motivation interviewing and interactive patient education. I will be providing weight management consultations under the supervision of Dr. José Alemán at the Manhattan VA, and performing research on the use readiness assement tools to predict and enhance patient outcomes.
