Dr Cork graduated in Biomedical Science from Stephenson College, Durham in 2008, followed by a PhD in Neurophysiology from St. Aidan’s College, Durham University in 2013. This was followed by post-doctoral research at University College London and a research fellow position at Imperial College London, in the laboratory of Prof. Sir Stephen Bloom, FRS. His research specialises in the control of hunger and body weight, particularly the role of gut hormones in the control of appetite.

Dr Cork is passionate about science communication and has appeared on numerous national and international TV and radio programmes and is regularly quoted in newspapers on a range of topics, particularly focussed on obesity, but also on various aspects of human physiology.

With a passion for widening access to higher education for individuals from under-represented backgrounds, Dr Cork sits on numerous national committees focussed on widening access to medical schools and is involved in instigating a number of initiatives within the School of Medicine to attract and retain such students.

Research interests

  • Obesity
  • Gut hormones
  • Gut-brain axis
  • Widening participation

Dr Cork has a specialist interest in the role of gut hormones in appetite control. His research has focussed on the role of glucagon-like peptide 1 (GLP-1) in the brain and its role is satiety, as well as the role of the vagus nerve in gut-brain signalling. He is also interested in widening participation, particularly in regards to entry to medicine.
