My research focused on the role of hypothalamic peptides in the control of energy homeostasis and body weight regulation.  It investigated the links between energy homeostasis and metabolic function, particularly the control of the thyroid and reproduction.  The research extended into how the gut sensed nutritional status and signalled to the appetite centers of the brain to regulate food intake.  

Researched focused on two gut hormones, Peptide YY (PYY) and Oxyntomudulin and how these gut hormones controlled food intake and body weight.  Following a number of studies in rodents and humans trials these discoveries were patented and formed the basis of the Imperial spin out company Thiakis.  This lead my focus into the comercial side of Imperial as Divisional Comercialisation Director and in 2007 I completed the Exec MBA programme at Imperial Colege Business School.  

During 2014 I undertook a project as part of REF assessment excercise.  I wrote the Impact Case studies for the Faculty of Medicine demonstrating the depth and breath of the research at Imperial.  I continue to teach the undergraduate medical students at Imperial.
