I am interested in analytical method development and refinement for compounds that have significant impact on the human nervous and endocrine system. I have worked with the US EPA to develop and test several methods to evaluate environmental levels of these compounds for most common matrices. Many of these compounds have been identified as very prevalent in environmental issues directly impacting human activities and provide fodder for litigious litigation. Another group of compounds closely related to extensively used agricultural pest controls has proven to be of interest in homeland security endeavors. A paucity of data is available on chronic exposure to these compounds and most long term human health assessments lack sufficient interaction data to be able to predict inherent risk with an acceptable level of certainty. I am interested in using these methods and data in refinement of fate and transport models and to generate more comprehensive human health risk assessment models.
