By appointment.


I joined the Maryland Institute for Applied Environmental Health at the University of Maryland, School of Public Health in 2014 after completing my postdoctoral work at the Center for Environmental Research and Children’s Health at the University of California at Berkeley. I also hold a joint appointment in the Department of Epidemiology and Biostatistics and I am Affiliate Faculty at the Maryland Population Research Center at the University of Maryland.

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, women, 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. My research also seeks to use qualitative research methods to design and implement culturally-appropriate interventions to reduce environmental health disparities among Latino, African American, and other minority populations.

I have experience working in children’s environmental health research, occupational health, science communication, working with Latino communities, and conducting exposure assessment and epidemiologic research.  I welcome the opportunity to establish new collaborations and to work with talented undergraduates, graduate students and post-docs. For more information, please contact me.
