Faculty Researchers Spotlight

Heidi Jones

Dr. Heidi Jones

The research conducted by Heidi Jones, PhD, MPH centers on strengthening the provision of reproductive and sexual health services.   As a young public health professional, Dr. Jones was heavily influenced by the United Nation’s Cairo Agenda from 1994.  This document shifted what had historically been a Malthusian “population control” movement into a human rights movement, recognizing the rights and agency of individuals in decisions about and control over their own fertility and sexuality.  This human rights and social justice framework for reproductive health, combined with the application of rigorous scientific methods, form the foundation of Dr. Jones’ research.

Over the last 20+ years, Dr. Jones has worked on many different aspects of strengthening reproductive health services including abortion services, contraceptive counseling and provision, diagnosis and management of sexually transmitted infections, prevention of sexually transmitted infections, including HIV, cervical cancer screening and prenatal and maternal health care.  She has worked on strengthening reproductive health services both within the United States and globally and has lived in both Senegal and Burkina Faso.

Currently Dr. Jones is leading an effort to understand patients’ and providers’ opinions and preferences for expansion of reproductive health services within primary care in New York State.  Should providers always ask patients whether they need reproductive health services during a primary care encounter?  If so, how can they do so in a patient-centered fashion that empowers individuals to make their own decisions about their reproductive health?

She is also collaborating with a non-profit organization, Hope through Health, on evaluating a project in northern Togo to reduce maternal and under five child mortality through strengthening health systems.   Dr. Jones has been vocal about her concerns about the associations seen in observational studies between use of the hormonal contraceptive injectable, depot medroxyprogesterone acetate, and acquisition of HIV infection, and led a Citizen’s Petition to the United States Food and Drug Administration to ensure that the product label for this contraceptive method states that it may increase risk of HIV infection (the FDA is still reviewing this request).

Dr. Jones sits on the editorial board of the journal, Contraception.

Karen Flórez

Karen Flórez

Karen Flórez’s training and research experiences are directly related to her deep-rooted interest in the sociocultural determinants of health. It was as as an undergraduate medical anthropology student that she first began to explore the intersection between culture and health. In college she focused on understanding medical systems and health equity among disadvantaged populations.

Upon graduation, Dr. Flórez investigated the barriers that impeded low-income Latino women from receiving preventive cancer screening exams for a nonprofit research firm. This experience solidified her commitment to public health and served as a catalyst for her decision to pursue research at the graduate level. She further developed her interest in the sociocultural determinants of health behaviors at Columbia University’s Mailman School of Public Health in the Department of Sociomedical Sciences. Here she was exposed to different methodological and theoretical perspectives, which enabled her to explore the ways in which sociocultural factors (e.g., acculturation, fatalism) shape health behaviors among Latinos.

Her dissertation that tested a novel theoretical framework to investigate whether patterns of assimilation were differentially associated with obesity among Latino adults. Since receiving her doctorate, she has continued her training with funds from a postdoctoral Diversity Supplement to an NCI-funded grant. This allowed her to use social network analysis to investigate the role of social networks and ties within the food environment in an urban food desert in Pittsburgh, Pennsylvania.

Dr. Flórez has continued her work on acculturation by conducting a cross-sectional analysis to investigate the association between exposure to the U.S. and obesity in a representative population of Mexicans living in the U.S. and Mexico. Collectively, these research experiences have enabled her to submit competitive applications to funders (e.g., RWJF New Connections, NIH), allowing her to further explore the interplay between sociocultural and neighborhood-level factors and their impact on childhood obesity among low-income children and adults.

Grace Sembajwe

Grace Sembajwe

Dr. Grace Sembajwe calls herself a “nomad.”

Born in Uganda, her early years were spent in Australia, Tanzania, South Africa and India. At age 17, while attending an International High School in South Africa, she won the international baccalaureate prize for her first research effort.

“I was studying the health effects of skin lightening cream in South Africa during Apartheid,” she says. “It seems so long ago now.”

Today, Dr. Sembajwe is an Associate Professor of Environmental and Occupational Health Sciences xat CUNY SPH. Her classroom environment is a dynamic praxis of lecture and fieldwork. She believes that only through theory and action can students develop the necessary foundation to listen and problem solve within their communities.

As a researcher, Dr. Sembajwe’s work examines the world of the occupational safety and health administration (OSHA). Current projects range from serving as principal investigator for a pilot project on OSHA needs in NYC entertainment establishments to co-investigator evaluating the health and safety of Latino day laborers after Hurricane Sandy. She is also co-facilitator with Professor Franklin Mirer on an injury/illness analysis of OSHA inspection data.

“Landing my first research position as an international student was a learning process,” she says. Inspired by her undergraduate professors, Dr. Sembajwe realized that clinical work could be transferred into occupational work. Practical lab experience was the next step. She reached out to one of her undergraduate professors and was able to secure research lab position.

But one barrier stood in her way. “As an international student, I needed a work visa.” After much stress she was uncertain if she would be able to stay in the US. Without much time to spare she discovered the F1 Visa program, ultimately gaining permission to stay in the country and begin her journey as a leader in OSHA research.

For students, Dr. Sembajwe has a consistent piece of advice: “Look for apprenticeships and internships to gain experience.” The first step is to get in touch with a professor, mentor or someone admired in the field. While she says that “for every success there has always been a mentor,” she adds that students shouldn’t necessarily limit themselves to one mentor.

Dr. Sembajwe’s counts the Scandinavian Journal of Work Environs, and the American Journal of Industrial Medicine among the favorites on her reading list. Her own published works can be found here.

Nevin Cohen

Associate Professor, The Graduate Center, at CUNY School of Public Health

Nevin Cohen

Dr. Nevin Cohen’s scholarship and professional experience in urban planning and policy development have focused on finding solutions to complex environmental health challenges facing cities. For the past decade, his research has explored the policies, governance systems, practices, and infrastructure to support socially just, healthy, ecologically resilient, and economically viable urban and regional food systems. As an expert on urban food policies and policymaking processes, Dr. Cohen is a Research Director of the CUNY Urban Food Policy Institute housed at the Graduate School of Public Health and Health Policy

A particular focus has been the practice of urban agriculture. Dr. Cohen was the lead analyst on a study that examined the environmental, health, and social impacts of urban agriculture on New York City, and the effects of city policies on urban food production.  This project identified policy strategies and measurement tools to strengthen the role of urban agriculture in improving health, economic development, environmental protection and social welfare, prompted the creation of an urban agriculture task force in New York City government, and led to a multi-year community based participatory research project to quantify the multifunctional (social, ecological, health, and economic) benefits of urban agriculture.

Building on this research, Dr. Cohen and colleague Kristin Reynolds studied urban agriculture activists who use their gardens and farming activities to address complex upstream determinants of health and well being such as structural racism, gender inequity, and economic disparities. Their research led to a forthcoming (summer 2016) book, Beyond the Kale: urban agriculture and social justice activism in New York City, which highlights this activism and profiles the activists and leaders, many of them people of color and women, whose strategies have often been underrepresented within the food movement.

Dr. Cohen’s research also has explored the potential for city governments to improve the food system by engaging in “strategic practice management,” intervening in the material elements, meanings, and know-how that shape everyday food practices – shopping, cooking, disposal — that structure and support seemingly entrenched socio-technical systems like food. This work illustrates how social practice theory can advance health policymaking by shifting the unit of analysis from individual behaviors to socially influenced practices.

Dr. Cohen is working with colleagues at the CUNY Urban Food Policy Institute, city agency staff, and community activists on a variety of research projects to improve New York City’s food system: measuring and evaluating fifteen years of changes to the food environment in East Harlem; identifying policies to improve access to healthy food by expanding and improving jobs in the food sector; exploring policies to advance equity in the food system; and devising methods to measure and mitigate the impacts of land use planning and zoning on local food environments.

Mimi Fahs

Professor, Hunter College and The Graduate Center, at CUNY School of Public Health

Mimi Fahs

From Research to Policy

The overarching goal of Mimi Fahs’s current research is to reduce health disparities among vulnerable underserved populations by applying health economic methods to help policy makers make informed decisions.

Her earliest research focused on the relationship between economics and public health outcomes. She discovered that while cost-sharing among the United Mine Workers led to decreased demand for health care services, as expected, it also led to unexpected changes in physician treatment patterns that actually increased physician revenue. This challenged the economic assumption that raising prices to consumers would help control health care costs.

Over the last 25 years, Dr. Fahs has continued to question economic assumptions, pointing out that preventive care was often overlooked in older adults, particularly minority older adults such as African Americans, Hispanics, or immigrants. She served as principal or co-investigator in pioneering research on the cost effectiveness of preventive screening for cancer (breast, prostrate, cervical) among older adults. These high-impact studies advanced economic methods, as well as the evidence base to inform payer benefit decisions for preventive care, including Congress and Medicare preventive screening benefits. For example, she developed the first cost-effectiveness analysis of a cervical cancer prevention program among older African American women in New York City. The surprisingly positive results led to Congressional mandate of a similar national-level study, contributing to Congressional passage of Medicare’s inaugural screening benefit for cervical cancer.

Dr. Fahs enjoys interdisciplinary collaboration and community-based partnerships that address pressing policy and program challenges. Using state-of-the-art health services research methods, she translates science into practice and produces evidence to help guide decision-makers in program and policy development. A 1992 landmark study of the cost of occupational illness helped influence the New York State legislature to initiate six occupational health centers. Another study, estimating the national cost of environmental disease among children to be over $55 billion annually, influenced NIH to establish five Children’s Environmental Health and Disease Prevention Research Centers.

Most recently at CUNY SPH, Dr. Fahs focused on neighborhood-based determinants of healthy aging. She led a team to develop the first representative survey of health status and health care needs of seniors attending senior centers in New York City. With policy and senior center leaders, she identified priorities for public heath prevention opportunities, demonstrating the effectiveness of chronic disease self-management programs in city senior centers.

Dr. Fahs works extensively with local community organizations. Currently, she is working with Union Settlement in East Harlem to evaluate a Naturally Occurring Retirement Community; with the Health and Hospitals Corporation to analyze utilization data for their Options program that will inform payment design; and with the Family Health Institute of East Harlem to demonstrate the cost-effectiveness of self-management programs implemented within Medicaid Health Homes. Internationally, she is working with New York University to train local providers and community health workers in tobacco control in Viet Nam, and analyzing the cost effectiveness of different approaches.

Dr. Fahs is often called upon to contribute her expertise to national scientific review committees, such as the Agency for Healthcare Research and Quality, the National Institutes of Health. She currently serves as Co-Coordinator for the Public Health Scholar’s Program at the CUNY School of Public Health, funded by the NYC Department of Health and Mental Hygiene.
