    Assistant Professor; Clerkship Director

    Dr. Deladisma recently completed the UF College of Medicine Research Training Academy (RTA) and has been chosen to be a Jax Scholar. The Jax Scholars program is a UF Health – Jacksonville internal scholars program that provides faculty protection from clinical duties for up to two-years so they may dedicate time towards research. Dr. Deladisma will use the dedicated time afforded by the Jax Scholar program to further her research interests. The focus of her work will be women’s health and the ways in which social determinants of health (SDOH) impact disease outcomes.

  • John D. Murray, M.D.

    John D. Murray, M.D.

    Associate Professor; Chief, Division of Plastic Surgery

    The principle goal of Dr. Murray’s clinical and laboratory practice has been to improve the quality of human life worldwide by developing and delivering regenerative protocols and products which are safe, effective and cost conservative. A large focus of his effort is related to better understanding the very complex but powerful characteristics of adipose-derived stromal cells (ASCs). As a required constituent in all types of human tissues, these cells may also serve as the critical constituent in the development of cell-based regenerative therapies as well as complex tissue engineering.

    Leigh A. Neumayer, M.D., M.B.A., M.S., F.A.C.S.

    Professor; Chair, Department of Surgery

    Dr. Neumayer has focused her scholarly activity in five main themes: surgical education, clinical trials, quality and outcomes, mentoring/faculty development and breast cancer. Her masters degree in clinical research design and statistical analysis laid a strong foundation for not only designing and conducting prospective trials, but also a deeper understanding of statistical analyses and other methodologies such as survey design and health related quality of life measurements. Combining the skills and knowledge gained from her masters program, she successfully led investigations in hernia repair techniques, breast cancer treatment, surgical quality and outcomes as well as surgical education techniques. Her work has also involved mentoring others in these and other pursuits. More recently she has focused her efforts toward the diagnosis and treatment of breast cancer via innovative technology and clinical trials.

  • Fern J. Webb, Ph.D.

    Fern J. Webb, Ph.D.

    Associate Professor; Co-Director, Center for Health Equity and Engagement Research

    Dr. Webb is an epidemiologist, who assists with research design, implementation and evaluation of projects conducted in clinical and community settings. Her work involves cancer, diabetes, hypertension and obesity. She has also led and contributed to research examining screening awareness and uptake (i.e., cancer), holistic health interventions, telehealth, and patient-centered/focused interventions. As a researcher committed to promoting community engagement best practices, she employs community engagement and participatory research models, grounded in the Principles of Community Engagement (CDC, 2001), such as Community Impact Theories, community health worker (CHW) models, and multi-directional and interactive models focused on under-served and under-engaged populations. In fact, 100% of service programs, research projects and community activities she has had the privilege and honor of contributing to seek to be intentional and purposeful in its attention to these principles. She has led research teams on a diverse array of community- and clinical- based projects. She also values opportunities to contribute to research designed to improve the lives of traditionally underserved and excluded populations.

    Dr. Webb serves as co-director for the Center for Health Equity and Engagement Research (CHEER), a central hub for research and community engagement activities that focus on improving equity, especially among underserved populations. CHEER provides access to resources and expertise that foster research and education efforts to empower residents, clinicians, organizations and communities. Dr. Webb also serves as co-investigator, and community outreach core leader at UF, for the National Cancer Institute funded Care2 Center (Florida-California Health Equity Center). The Care2 Center is designed to eliminate prostate and pancreatic health disparities among Black and Latinx populations in Florida and in California.
