Trace Metal Ecotoxicology and Biogeochemistry Laboratory

Research Interests
  1. Metal biogeochemistry and ecotoxicology
  2. Marine pollution
  3. Physiological ecology of aquatic organisms
  4. Harmful algal bloom

The overall research program in Dr. Wang's lab is the understanding of trace metal-biota interaction in the aquatic environments (both marine and freshwater systems). Many trace metals are biologically essential but can be toxic at elevated concentrations. The research emphasizes on the multidisciplinary studies, including ecotoxicology, physiology, biogeochemistry, environmental sciences, biological and chemical oceanography, and mathematical modeling. The researches are herein categorized into different fields, each with several representative publications from the lab in recent years.
