Vice President / ENVIRONMENTAL STATISTICIAN
lorraine@exadata.net
Ms. Brown is an environmental statistician with 30 years of professional experience in the assessment and interpretation of environmental and biological data. Past projects have integrated environmental quality data from surface water, sediments, and soils, with biological endpoints including abundance, bioaccumulation, and bioassay data from terrestrial, marine, and freshwater flora and fauna. She has extensive experience developing statistical designs for sampling programs in a variety of settings in the US and Canada, including dredge material suitability and disposal site monitoring, regional background surveys of Puget Sound sediments, trend monitoring, and site characterization. Her knowledge of statistics and the scientific method has equipped her with the ability to incorporate statistical rigor into the sampling of complex ecological systems, and the subsequent analysis of the data obtained.
Ms. Brown is skilled at conducting graphical and statistical analyses using R scripts (R: a language and environment for statistical computing) for one-time evaluations, or batch processing of repetitive analyses associated with large database systems. She is eager to utilize shared analytical tools (e.g., R and RMarkdown) to facilitate data analysis and interpretation among colleagues and clients. At Exa, Ms. Brown has provided statistical and technical support on projects such as standardizing and stream-lining the statistical evaluation of sediment toxicity data, evaluating stochastic models used for predictions and decision making, and generally providing a statistical perspective on the collection, interpretation, and utility of environmental data.
