Dr.Gooneratne also runs a Sleep Disorders Clinic for Seniors in an effort to address the medical needs of older patients with sleep disorders. In addition, Dr. Gooneratne is the Associate Director of the Masters in Translational Research Program, with a focus on Entrepreneurial Science education at the University of Pennsylvania's ITMATEd program.
