I am interested in how alterations in metabolic status effect brain function.
My laboratory is currently focused on delineating the mechanism(s) of action of circulating hormones, that are regulated by feeding, on protecting against nerve cell loss associated with Parkinson's and Alzheimer's disease. We are also keen to understand how these circulating hormones may modulate neural stem cell (NSC) plasticity in adults to promote memory function.

Teaching

  • PM-139 Human Physiology I

    This module aims to provide an understanding of the structure and function of key physiological systems of the human body. Human physiology is the study of how our body works in an integrated way. A central principle of human physiology is homeostasis, the maintenance of a relatively stable internal environment. Failure to maintain homeostasis disrupts normal function that may lead to disease (or pathophysiology). Students will be taught the key concepts of homeostasis in the physiological systems of the body, enabling the student to understand the consequences of pathophysiology to human health. Students will gain practical experience in assessing cardiac function during two laboratory based exercises.

  • PM-347 Human Immunopathology

    The module aims to provide students with a greater understanding of the human immune system and the causes of a range of diseases associated with immune dysfunction including autoimmune diseases, metabolic disorders and neurological conditions.

  • PM-368C Doctor as a Practitioner 4

    This module enables medical students to consolidate their clinical and communication skills within their clinical practice, building on what they have learned in the previous years and preparing themselves for the foundation year training programme. Focusing on the notion of the Doctor as a practitioner (Tomorrow's Doctors, GMC 2009), this module enables students to further enhance their skills within a safe but clinically-focused environment.
