研究领域

Environmental endocrinology My laboratory focuses on the neural and endocrine mechanisms underlying organism-environment interactions. We are particularly interested in the neural pathways for environmental signals affecting seasonality, mechanisms of coping with environmental stress (allostasis), and the social modulation of hormone secretion. This research also interfaces with how animals deal with global climate change, endocrine disruption and conservation biology.
