Profile

Dr. Radhika Kelkar completed her medical education in Maharashtra, India, followed by psychiatry residency training at the prestigious National Institute of Mental Health and Neurosciences (NIMHANS) in Bengaluru, India. During residency, she developed a strong interest in neuromodulation, which led her to pursue a specialized fellowship in non-invasive brain stimulation at NIMHANS. Through this fellowship, she gained expertise in the clinical practice and teaching of various neuromodulation techniques, including electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), and transcranial direct current stimulation (tDCS).

She further expanded her clinical and research expertise through an additional fellowship in Brain Stimulation at the Centre for Addiction and Mental Health (CAMH), University of Toronto, where she refined her skills in this rapidly evolving field.

Dr. Kelkar currently leads the ECT service at Parkwood Institute and works on the geriatric psychiatry inpatient unit. She is actively involved in clinical teaching, with a focus on neurostimulation, mood disorders, and late-life depression. Her research interests include optimizing the treatment of depression through novel neuromodulation techniques and treatment protocols.

Her current research work includes evaluating accelerated treatment protocols for comorbid PTSD and major depressive disorder, using digital phenotyping techniques to monitor response to rTMS in major depression, and optimizing ECT treatment delivery to improve outcomes in late-life depression.
