My major research interests are the determinants of physical activity particularly bicycling in populations, bicycling injuries, occupational and environmental health and sports injuries. The bicycle-related research is an area I am trying to develop. My interest in occupational health is informed by ten years of work in the 1980s and 1990s with non-profit organizations advocating for improved workplace health conditions in Wisconsin and North Carolina. Since then I have been involved in research documenting racial and ethnic disparities in work-related cancers and risk assessment research comparing cancer risks estimated from epidemiologic studies with risks estimated from animal bioassays. My CV contains a complete list of my publications from my research in these areas. I teach epidemiology and environmental health to both MPH students and undergraduates.

Dermatological Illnesses of Immigrant Poultry-Processing Workers in North Carolina 2005 897 The authors designed this study to assess skin ailments among male Latino poultry-processing workers in one plant in North Carolina. Because conditions in poultry plants expose workers to multiple agents affecting the skin, the number of skin ailment...
Diagnosed Skin Diseases Among Migrant Farmworkers in North Carolina: Prevalence and Risk Factors 2007 390 Skin diseases are common among farmworkers, yet little research documents their prevalence and risk factors. This analysis documents the prevalence of skin diseases among farmworkers in North Carolina, examines variation in the prevalence across the ...
Dose-response relation between acrylamide and pancreatic cancer 2001 176 In their 1999 study of workers exposed to acrylamide, Marsh et al conducted an SMR analysis, and fitted several relative risk regression models to the data.1 In each analy sis, they found risk of pancreatic cancer increased by about twofold for ...
Factors Associated with Misperception of Weight in the Stroke Belt 2008 370 BACKGROUND: Understanding the reasons for over-weight and obesity is critical to addressing the obesity epidemic. Often the decision to lose weight is based as much on one’s self-perception of being overweight as on inherent health benefits. OBJECTI...
Green Tobacco Sickness and Skin Integrity Among Migrant Latino Farmworkers 2008 687 Background: Green tobacco sickness (GTS) affects approximately one-quarter of tobacco workers. The primary aim of this analysis is to expand existing knowledge of GTS risk factors by delineating the association of measures of skin integrity with the ...
Health Care Utilization Among Migrant Latino Farmworkers: The Case of Skin Disease 2009 883 Context: Skin diseases are common occupational illnesses for migrant farmworkers. Farmworkers face many barriers in accessing health care resources. Purpose: Framed by the Health Behavior Model, the purpose of this study was to assess health care ut...
Incidence and Risk Factors for Concussion in High School Athletes, North Carolina, 1996–1999 2004 732 A prospective cohort study was used to quantify risk factors for sports concussions. Analysis was based on a stratified cluster sample of North Carolina high school athletes followed during 1996–1999. Clustering was by school and sport, and the sampl...
Mortality From Six Work-Related Cancers Among African Americans and Latinos 2000 310 Background: Ethnic minorities have been omitted from many occupational health studies, despite their substantial contributions to the labor force and documented cases of high exposures in some settings. To describe the occurrence of potentially work-...
Occupational Bladder Cancer Mortality Among Racial and Ethnic Minorities in 21 States 2000 511 Background: Occupational bladder cancer mortality among minority racial/ethnic groups is not well described compared to occupational bladder cancer mortality among non-minority males in the United States. Methods: Race/ethnicity- and sex-specific bl...
Occupational exposure assessment in case-control studies: opportunities for improvement 2002 445 Community based case-control studies are an efficient means to study disease aetiologies, and may be the only practical means to investigate rare diseases. However, exposure assessment remains problematic. We review the literature on the validity...
The prevalence of melasma and its association with quality of life in adult male Latino migrant workers 2009 1362 Background: Melasma is a common condition of Latino women that detracts from their quality of life (QOL).
