Ajaz Ahmad Bhat

Research Scientist


Dr. Ajaz A. Bhat completed his Ph.D. from one of the premier institutes (All India Institute of Medical Sciences, AIIMS) in India. During his Ph.D., his main focus of research was the development of peptide based vaccine for Plasmodium vivax Malaria . In addition, he has some experience with HIV and Leprosy. He moved to Vanderbilt University Medical School for postdoctoral fellowship where he joined the Division of Surgical Oncology, Dept. of Surgery. During his five years of training at Vanderbilt, he has gained wide experience in the field of cancer biology. He has attended many international meetings, conferences, symposia to present his research results. Currently he is working as a research scientist in the Department of Surgery, Vanderbilt University Medical School, Nashville, Tennessee.
