About Giridhar Kalamangalam

Giridhar Kalamangalam, MD, DPhil, is a Wilder Family endowed professor and the Division Chief of Epilepsy at the UF College of Medicine. He was recruited by UF Health to his current position in September 2017.

Dr. Kalamangalam was born and raised in India, where he completed medical school at the Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER) in Puducherri. He was a Rhodes scholar to Oxford University, England, where he earned a master’s degree (MSc) in applied mathematics and a research doctorate (DPhil) in mathematical biology. He obtained clinical training in internal medicine by rotation in various hospitals in the British National Health Service and completed a general neurology residency at the Institute of Neurological Sciences, Glasgow. He was fellowship trained in epilepsy and EEG at Cleveland Clinic.

Dr. Kalamangalam’s career has been devoted to the care patients with epilepsy and research in the science of, and around, epilepsy. His publications have appeared in multiple peer-reviewed journals, and his work has been funded by the National Institute of Neurological Disorders and Stroke as well as the American Epilepsy Society, among others.
