Academic Achievements & Community Involvement
Clinical Care
Overview
Abhishek Kumar, MD, is a nephrologist who specializes in the care of patients with complex kidney transplant needs. He focuses on diagnosing and managing conditions related to kidney transplantation and aims to improve patient outcomes through comprehensive care strategies.
Dr. Kumar is dedicated to advancing the understanding of chronic kidney disease in patients who have received non-kidney organ transplants, with the goal of identifying those who might benefit from multi-organ transplants. As an associate professor at Yale School of Medicine, Dr. Kumar is involved in research that seeks to enhance predictive measures for chronic kidney disease in transplant patients.
He received his medical training from Jawaharlal Institute of Postgraduate Medical Education & Research in India. He completed his residency at the University of Illinois, followed by a fellowship in nephrology and transplant nephrology at the University of Iowa.
