Research Expertise

Dr. Padala is a Geriatric Psychiatrist who obtained his training at the Creighton-Nebraska psychiatry program. Dr. Padala’s research interest is in the treatment of behavioral problems associated with dementia particularly apathy. He is also interested in studying the impact of apathy on outcomes of diabetes and the role of motivation in adherence to activity promotion. He is currently conducting pharmacological and non-pharmacological clinical trials for treatment of apathy. He leads the Transcranial Magnetic Stimulation lab at the GRECC, a Center of Excellence in the VA to promote geriatric knowledge through research, education and innovative clinical models.

As the Associate Director for Clinical programs for GRECC, Dr. Padala oversees seven innovative Clinical Demonstration Projects (CDPs) which utilize Quality Improvement/ Implementation Research methodology to bridge the gap between evidence based medicine and clinical practice. These CDPs are funded through grants from the Office of Rural Health, Office of Health Equity and T21 grants from the Department of Veterans Affairs.
