Dr. Ryan Marek, PhD

I am one of the leading experts in pre-surgical psychological evaluations. I have authored a book titled “Psychological Assessment of Surgical Candidates: Evidence-Based Procedures and Practices” and actively engage in society work associated with the American Society for Metabolic and Bariatric Surgery to advance training and science related to bariatric surgery. My clinical training experiences have largely centered around assessing the intersections of medical/health, psychological, and social aspects of individuals to facilitate successful outcomes in medical settings. With training from some of the leading experts in psychological assessment, I am also proficient in conducting disability/worker’s compensation evaluations, pre-employment screening, and general psychodiagnostic evaluations in addition to pre-surgical assessments.

I am licensed in the state of Texas (#38086) and hold a PsyPact license to practice in other states.

My research focuses on understanding how psychological factors contribute to medical outcomes. I have over 60 peer-reviewed publications, primarily focused on pre-surgical psychological evaluations and their predictive value for various outcomes. I use my research findings to assist patients in managing risk factors before and after surgery to optimize their outcomes. Additionally, I have a keen interest in psychological assessment, particularly in the use and study of the Minnesota Multiphasic Personality Inventory (MMPI) in both research and practice. I have been recognized by several national organizations with early-career research awards for my contributions to pre-surgical psychological evaluations. Currently, I am the Principal Investigator on novel psychological interventions for Type 2 Diabetes. I also serve as an Associate Editor for two esteemed journals in the field – Psychological Assessment and Surgery for Obesity and Related Diseases.
