I am an Associate Research Scientist with the University of Maryland Center for Environmental Science at the USEPA Chesapeake Bay Program. My main role is to work with scientists, professionals, and managers in the Chesapeake Bay partnership to explore natural and anthropogenic-based causes behind the current status and long-term trends in the water quality of the streams and rivers in the Bay watershed. I am interested in applying scientific principles and statistical approaches to quantify nutrient and sediment loads from watersheds and examine their impacts on receiving waters. Specific research areas include but are not limited to: (1) quantification of water-quality trends and uncertainties; (2) improvement of statistical methods for riverine load and trend estimation; (3) evaluation of natural and anthropogenic controls of riverine loads; and (4) investigation of impacts of riverine loads on receiving waters (e.g., estuaries). I obtained my Ph.D. degree from the Department of Geography and Environmental Engineering at Johns Hopkins University. I also hold two Master of Science degrees from Johns Hopkins University, one in environmental engineering and the other in statistics.
