Research interests

Understanding the various ways that neurones change in response to their environment is the core focus of our laboratory.

Using biochemical, electrophysiological, and behavioural methods, combined with animal models, we study two main topics:

  1. The neurobiological embedding of adversity. We hope to understand how adverse environmental factors (such as malnutrition and psychosocial stress) can affect the development and/or function of brain areas related to learning and memory.
  2. Biological characteristics that influence outcome from brain injury. We also hope to understand how variables like sex, age, and anatomical region can affect the cellular changes that arise following stroke-like injury.
