Dr. Kalakonda received his doctorate degree from Osmania University, Hyderabad, India. Doctoral dissertation was on genetic and biochemical studies in families with essential hypertension. After completing his Ph.D. degree, he worked as a Research Officer in the Department of Genetics, Osmania University, India. During this time, he focused on cytogenetic and molecular aspects of ocular disorders. He joined as Post-Doctoral Research fellow in Dept. of Ophthalmology and Microbiology, University of Maryland.

Dr. Kalakonda joined the faculty of University of Maryland School of Medicine as a Research Associate in 2007. At present he is working in Department of Pathology. His basic interest is to find out molecular aspects of any disease.
