Watershed Effectiveness Data Analyst
Chesapeake Bay Program Office
Dr. Qian Zhang is an assistant research scientist with UMCES at the USEPA Chesapeake Bay Program. His 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. This collaborative effort is critical to defining the success of Chesapeake Bay restoration efforts to date and to making science-based management decisions in the future.
Dr. Zhang is 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).
Zhang obtained his Ph.D degree from the Department of Geography and Environmental Engineering at Johns Hopkins University. His doctoral dissertation focused on nutrient and sediment export from major tributaries to the Chesapeake Bay. Zhang also holds two Master of Science degrees from Johns Hopkins University, one in environmental engineering and the other in statistics.
