My research field is Fisheries Population Dynamics, a branch of Ecology that focuses on the changes in the abundance and structure of fisheries populations. Its important applications are fisheries stock assessment and fisheries management. To be more specific, my current projects can be classified into the following areas: 1) Develop more realistic assessment models with uncertainty included. 2) Analyze alternative management strategy evaluation systems including simulation models. 3) Standardize data collection and data processing for fisheries assessment. 4) Develop ecosystem models for the ecosystem-based stock assessment and management.
