I have over 20 years of experience as an engineering research scientist and technical writer/editor. I have analyzed data for various projects on human exposure to indoor contaminants and written/compiled and edited numerous technical documents and articles for Wilkes Technologies. Recent projects include writing/editing the Help files for the Total Exposure Model (TEM); researching and modeling indoor carbon monoxide exposure; and researching, analyzing data and writing/editing  reports on indoor exposure to water-borne contaminants, including analyses of probability distributions for shower, bath, laundry, dishwasher, clothes washer, toilet and faucet uses for various U.S. subpopulations. Reports and papers included literature reviews on pesticide and microenvironmental modeling and water-use/activity pattern data; analyses of the National Activity Pattern Survey (NHAPS) and Residential End Uses of Water Study (REUWS) databases; and results from various exposure-modeling projects. During this time, I wrote the monthly “Buyer’s Guide” page for American Chemical Society’s journal, Environmental Science and Technology, and edited several articles for the American Society of Civil Engineers’ journal, Civil Engineering. I have also published seven newspaper articles on science related subjects, including a feature article on carbon monoxide in the Washington Post, Home section. My  prior experience is in storm water system design, landfill design, and surveying.
