Research Interests

I am broadly interested in how the environment, particularly both natural and anthropogenic stressors, affects animal physiology. My research often spans across multiple fields, including toxicology, endocrinology, immunology, and ecology. To investigate the effects of environmental stressors on animal physiology, my collaborators and I mainly use long-lived, top-trophic species, namely crocodilians and turtles.
