  • Assistant Professor of Environmental Health Sciences at CUMC
Profile Headshot

Overview

My current research focusses on elemental speciation analysis of environmental chemicals, and how high-quality analytical methods can contribute to our understanding of exposure sources, metabolic pathways, and potential health effects. My research goals merge into improving the general health of populations, focusing particularly on disproportionally affected communities and to reduce environmental health disparities in underserved populations. My past and current research interests are directed towards advancing our understanding of the biochemical cycles of metals, metalloids, and biomolecules thereof. My focus lays on their interactions with and consequences for human health after environmental exposure. I am particularly interested in the quantitative analysis of metalloids, especially those bound into organic molecules, and how the analytical data can inform us about the biogeochemical pathways and distribution of these contaminants, their toxicity, and their connection to human diseases. In my current work, I focus on the development and application of methods for the simultaneous and time-efficient determination of various health-relevant chemical elemental species.
