Janet M. Okamoto, Ph.D., conducts research focused on network analysis and health behavior with a primary interest in the social and cultural determinants of health behaviors. Dr. Okamoto is specifically interested in the use of social network methods and measures to better understand interpersonal and organizational relationships and their influence on health attitudes, norms, beliefs, decisions and behaviors.

Dr. Okamoto also has an interest in understanding how to utilize network influences for use in interventions to promote health behaviors. She has worked across a broad array of public health and health behavior topic areas, including tobacco use, diet and physical activity, and substance use.

Focus areas

  • Social networks. Dr. Okamoto's work seeks to explore and study the influence of social networks on health behavior. She then aims to develop ways to harness this influence through intervention to have a positive effect on health.
  • Health disparities and health equity. Dr. Okamoto works closely with colleagues on research addressing disparities in health care and health outcomes. Since arriving at Mayo Clinic, she has maintained a close connection to community engagement research activities, with a particular focus on health equity.
  • Program evaluation. Dr. Okamoto serves as a program evaluator for Mayo Clinic's Center for Clinical and Translational Science and has taught and developed training on evaluation from a public health perspective.
  • Team science. Since her postdoctoral work at the National Cancer Institute with the Science of Team Science group, Dr. Okamoto maintains an ongoing interest in the study of team science and understanding how transdisciplinary research teams can produce high-impact output.

Significance to patient care

Dr. Okamoto's research impacts patient care through identifying and understanding how social and behavioral factors influence health behaviors in order to develop more effective preventive interventions.
