Dimitris N Kiosses

Dimitris N Kiosses serves as Professor of Psychology in Psychiatry at Weill Cornell Medical College's School of Medicine since 2021. His academic affiliations center within the Department of Psychiatry with a focus on geriatric mental health services and research.

His educational background includes a B.S. from Tufts University (1992), M.A. (1994), and Ph.D. (1999) from Adelphi University, establishing his foundation in clinical psychology with specialization in geriatric populations.

Dr. Kiosses' research primarily investigates late-life depression, suicide prevention in older adults, and cognitive-behavioral interventions for comorbid conditions. His work emphasizes Problem Adaptation Therapy (PATH) development and implementation, particularly for depressed elders with cognitive impairment or chronic pain. Recent publications demonstrate growing focus on digital mental health tools, ecological momentary assessment, and international applications of geriatric interventions. His studies frequently examine emotion regulation mechanisms, neurocognitive correlates of depression, and implementation science approaches for real-world settings.

Analysis of his 15 most recent publications reveals consistent thematic progression toward transdiagnostic approaches for late-life mental health, with increasing emphasis on technology-enabled interventions, cross-cultural adaptation, and precision medicine applications. The work spans clinical trials, implementation studies, and neurobiological investigations, predominantly targeting depression-suicide pathways in aging populations.

Dr. Kiosses maintains active research mentorship through his leadership of multiple NIH-funded projects. His grant portfolio demonstrates particular strength in securing R01-level funding from NIMH and NIA for innovative geriatric mental health interventions.

As Principal Investigator, he directs the Problem Adaptation Therapy research program which has evolved from home-based depression treatment (PATH) to specialized adaptations including PATH-Pain and suicide prevention applications. His work increasingly incorporates digital health components and focuses on implementation within primary care and community settings.
