Dr. Qubin Qin earned his Ph.D. in marine science from the Virginia Institute of Marine Science (VIMS) at William & Mary in 2019. Since August 2023, he has been an Assistant Professor in the Department of Coastal Studies at East Carolina University. Much of his research involves analytical theory, data analyses, and the development and simulation of numerical models. One of his primary research goals is to generate scientific insights that can be effectively applied to address real-world challenges in estuarine and coastal environments. His research provides advisory services to federal, state, and local agencies, aiding in the management of coastal and estuarine water quality issues affected by climate change and human activities.

Research Interests

Dr. Qin’s research covers a broad range of topics, such as physical transport processes, physical-biological interactions, coastal environmental issues (e.g., eutrophication, hypoxia, harmful algal blooms, saltwater intrusion, contaminants, pathogen pollution, stormwater pollution, habitat degradation, and conservation of living resources), and model development (including analytical, process-based, habitat, particle-tracking, and data-driven/machine learning models).
