Environmental Toxicants Related to Human Disease
On a daily basis, we are exposed to environmental agents that are a potential risk to human health, for example, sunlight, food related chemicals and environmental toxicants. These agents can damage biomolecules in cells, eventually leading to chronic disease and aging. We are interested in elucidating adverse cellular outcomes that arise from exposure to these ubiquitous environmental toxicants. To this end, we are developing in vitro platforms and high content imaging to measure endpoints of toxicity in cells. In addition, we combine molecular biology and chemical biology approaches to evaluate genomic alternations that arise from exposure to environmental toxicants, in particular UV radiation. Overall, understanding the molecular mechanisms of these processes will allow us to devise predictive models and discover biomarkers for human risk assessment and disease prevention.
