Why are insects so successful in so many different environments? In large part, the extraordinary diversity of insects is mirrored in the diversity of their environmental physiology. Dr. Sinclair studies insects survive extreme environments – particularly cold places – exploring the physiological mechanisms that help them survive, placing those mechanisms into ecological context. His work spans molecular and cell biology to evolution, and he often explores those processes through the lens of organismal thermal biology and metabolism – and he has a particular passion for the insects that can survive being frozen solid. Dr. Sinclair’s research has applications in pest management, cryopreservation, and in optimising insect production for food and feed.

Courses Taught
Dr. Sinclair will teach in the areas of insect physiology and thermal biology.
Academic focus: Insect environmental physiology Research summary: I study how insects survive and thrive in harsh environments. Although we center our research on the insect, we follow mechanisms all the way to molecular biology and consequences...
