Tom Gordon, PhD

Professor of Psychology, University of Massachusetts- Lowell

Dr. Gordon has had extensive experience conducting research studies involving a variety of research approaches, with particular emphasis on perceptual mapping, for such clients as: ABC Television Network; World News Tonight program; ABC Spot Sales Division; and numerous national corporations. For the past decade he has concentrated on health research and the use of perceptual mapping and segmentation approaches to develop more effective health campaigns. Much of this research has involved working with low-income, low-health-literacy minority communities and has successfully produced tutorials and message strategies that are culturally and developmentally appropriate for these target groups. These studies have covered diverse areas of application including colorectal cancer screening, radiological terror, smallpox vaccination, avian flu attitudes toward vaccination and quarantine, public perceptions of emergency preparedness, and perceptions of patients by HIV/AIDS caregivers.

Amy B. Jessop PhD, MPH

Director of Research at Prevention Point Philadelphia 

Dr. Jessop’s work focuses on the prevention, screening and treatment of infectious diseases, particularly vaccine-preventable infections and viral hepatitis. She is a founder and Director of HepTREC, a community-based organization with a mission to reduce the impact of viral hepatitis. She approaches viral hepatitis and its associated issues of substance use, liver diseases, health disparities and health policy through advocacy, community-based programs, and research. Dr. Jessop’s research is focused in two major areas: (1) immunization policies and practices, and (2) improvement of health service access and delivery. Health service improvement research includes examination of adoption and implementation of clinical practice guidelines. Immunization-related projects examined immunization registries laws and statutes, subspecialty physician immunization practices, readiness of VFC providers to implement vaccination recommendations, and Hispanic parents’ attitudes and beliefs about HPV vaccination of girls. Hepatitis-related projects examined infection prevention policies and practices in police departments, descriptive epidemiology of viral hepatitis in Philadelphia’s methadone maintenance programs, barriers to prevention and care for viral hepatitis, identification of readiness factors for viral hepatitis treatment, and development of mHealth tools to improve hepatitis C treatment initiation.

Michael Hall, MD, MS

Director of the Department of Genetics, Fox Chase Cancer Center

Dr. Michael Hall is a GI oncologist and a clinical cancer geneticist, and has found over the years that his strongest skills are in helping his patients and their families to understand the complicated risks of cancer screening, surgery and treatment, to weigh the different options for treatment, and finally to develop a plan that is both in line with cutting edge research but also with their personal needs and preferences for their health and their lives. In cancer medicine, there is no longer a one size fits all approach, and in his practice, Michael strives to build on his patients’ unique strengths and to further bring the multi-faceted expertise of his colleagues at Fox Chase and his colleagues nationally to offer each of his patients the best care he possibly can.
