CSDMS-related interest

I am particularly interested in computationally-intensive modeling and synthesis of large-scale data sets for watersheds and other ecosystems. My PhD research focuses on long-term export of nutrients and sediment from the Chesapeake Bay watershed. Specific areas include (1) evaluation of long-term water-quality trends and uncertainties; (2) improvement of statistical methods for riverine flux estimation and trend analysis; (3) analysis of patterns of watershed constituent export and controlling factors.

As a watershed data analyst (assistant research scientist) at the USEPA Chesapeake Bay Program (CBP), my main role is to work with professionals, managers, and scientists in the Chesapeake Bay partnership to explore natural and anthropogenic-based causes behind the observed current status and long-term trends in the water quality of the streams and rivers to the Chesapeake Bay, which is critical to defining the success of Chesapeake Bay and watershed restoration efforts to date and to making science-based management decisions in the foreseeable future.
