Research Summary

I have over 25 years of research experience conducting studies in health disparities among underserved US minority populations, with a particular emphasis on Latino health. Born and initially educated in Argentina, I obtained advanced degrees in the US in public health. I am currently a professor in the Department of Medicine at UCSF, Director of the Medical Effectiveness Research Center, and a co-director of the Investigator Core of the Center for Aging in Diverse Communities.

From the beginning of my research career, I have focused my efforts on examining health disparities across the cancer-care continuum. I have examined cancer prevention among adolescents; conducted studies in cervical, breast and colorectal cancer screening and follow-up of abnormalities; studied treatment decision making after cancer diagnosis among Latina women; and looked at recruitment barriers, facilitators, and strategies for improving minority participation in cancer-related research.

My research has included epidemiological studies and assessing barriers to and facilitators of health behaviors, as well as the development, implementation, and evaluation of health interventions to improve health outcomes. Participants in my studies have different language preferences and are of diverse ethnic backgrounds, age groups, levels of education, occupations, and socioeconomic and health statuses. I have used a variety of venues and methods for recruiting minorities and people of lower socioeconomic status, including clinic panels, population registries, random-digit dialing, and direct contact.

I have a long history of utilizing qualitative and quantitative research methods with health care organization representatives, health providers and patients. My research has been funded by federal and state agencies and private foundations, and my publications represent diverse areas of research.
