I have over 20 years of experience as a researcher, principal investigator, and consultant in public health with a focus on environmental and occupational health, epidemiology, and toxicology. I authored over 30 peer-reviewed publications in environmental/occupational health and epidemiology. My PhD and later work heavily focused on environmental and occupational studies, assessing human exposures to chemical mixtures and their link to health outcomes. I designed and directed studies in different populations, including roofers, welders, coke oven workers, and Air Force personnel. Over the last few years, I worked as an expert witness in legal cases evaluating toxic exposures, reviewing existing literature, and preparing reports. For example, I recently prepared a causation report on the link between glyphosate exposures and the risk of non-Hodgkin’s lymphoma. My work has focused on human exposures to chemical mixtures and related health outcomes. Some example mixtures are: - Pestici...
