Research Interests:
Antifreeze proteins and cold adaptation in fish. A number of marine fish produce antifreeze proteins to protect themselves from freezing in a sub-zero, ice-laden marine environment. The research we are carrying out focuses on these antifreeze proteins and their physiological regulation mechanisms of action, diversity, evolution and potential economic value in the field of biotechnology.
