, PhD, MSc

As an exposure scientist and environmental epidemiologist, my research bridges the fields of exposure science and environmental epidemiology to advance our understanding of how environmental factors influence human health. My work focuses on elucidating exposure-response relationships to inform evidence-based public health policies and interventions aimed at mitigating harmful exposures and enhancing health outcomes. Specifically, I investigate environmental exposures to endocrine-disrupting chemicals and their health effects, with a particular focus on occupational groups, pregnant women, women of reproductive age, and children. My research has explored exposures from personal care products, cleaning agents, pesticides,  flame retardants, PFAS, and other endocrine disrupting chemicals while also validating biomarkers to improve exposure assessment methodologies.

I integrate both quantitative and qualitative research methods to develop actionable strategies for reducing harmful exposures. 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 and their potential effects among hairdressers, examining the impacts of environmental agents on hormones, and assessing environmental exposures and associated health risks in Latin America. 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 neglected communities.

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