Experiences & Accomplishments
As an exposure scientist and environmental epidemiologist, I seek to conduct novel translational exposure science research to better understand exposure-response relationships. The ultimate goal of my research is to inform the development of public health policies and practices, and identify potential interventions to reduce environmental exposures and improve health. My research focuses on characterizing environmental exposures to endocrine disrupting agents and examining their potential health effects on highly vulnerable, low-income and minority populations underrepresented and understudied in public health research, including occupational populations, pregnant women and women of reproductive age, and children. To this end, I have examined determinants of exposure and health outcomes associated with chemicals in personal care products, cleaning agents, pesticides, and flame retardants; and validated biomarkers of exposure. My research also seeks to integrate qualitative research methods to design and implement culturally-appropriate interventions to reduce environmental health disparities among Latino, African American, and other minority populations.

In collaboration with colleagues from the Johns Hopkins School of Medicine and the University of Texas Dell Medical School, I am currently investigating the role of environmental exposures on asthma morbidity among inner-city children. Other projects I'm currently engaged in include assessing occupational exposures among hairdressers, examining the impacts of environmental agents on male hormones, and assessing environmental exposures in a U.S.-based Central American population. I am also a Co-Investigator for the Environmental Influences on Child Health Outcomes (ECHO) Data Analysis Center at Johns Hopkins. I have experience working in children’s environmental health research, occupational health, science communication, and working with underrepresented and understudied communities.

I welcome the opportunity to establish new collaborations and to work with talented undergraduates, graduate students, and postdocs.
