Dervla O’Malley received a first class BSc (Hons) degree from the University of Ulster, Coleraine in 1999. As part of this degree she spent 13 months in the University of Nevada, Reno for which she was awarded a Diploma in industrial studies. She carried out her doctoral studies at the University of Dundee having received a Muir Russell Scholarship and subsequently undertook a post-doctoral fellowship at the Cambridge Institute for Medical Research in the University of Cambridge. She returned to Ireland in 2007 and spent 4 years as a senior postdoctoral scientist in the Laboratory of Neurogastroenterology in the APC Microbiome Institute in University College Cork. In December 2011 she joined the Department of Physiology as a lecturer. She is also a faculty member of the APC Microbiome Institute.

The theme of Dervla’s research is neuroimmune and neuroendocrine interactions in the gastrointestinal tract. Of particular relevance is the importance of immune and endocrine factors in gastrointestinal dysfunction in disorders such as irritable bowel syndrome (IBS).

Dervla has published more than thirty peer-reviewed manuscripts, two book chapter and over sixty conference publications and has a H-index of 19. She is is a member of the editorial board for 'World Journal of Gastroenterology' and ‘Frontiers in Neuroscience, Physiology & Neurology’ and an invited reviewer for over twenty journals in the field of physiology and neuroscience. 

Research Interests

Irritable Bowel Syndrome (IBS) is characterised by debilitating symptoms such as abdominal pain, bloating and altered bowel habit and affects 10-20% of the world’s population. As current therapeutic strategies are limited by side effects and safety issues, new avenues of research in this field are highly desirable. Stress is generally accepted to be a key factor in the initiation, persistence and severity of IBS symptoms but a growing body of data now indicates the central role that immune activation has in the pathophysiology of the disorder. Nutrient associated hormones such as leptin, ghrelin and glucagon-like peptide 1 (GLP-1) may also be important in the exacerbation of symptoms following nutrient intake. The microbiome is altered in IBS patients and may be important in this functional bowel disorder, hence we are striving to understand how microbes in the external gut lumen could modulate host gut homeostasis.

Current Projects:

Department of Physiology funding (Oct 2014 - 2017).  

Investigation into the potential of GLP-1 mimetics for treatment of functional bowel disorders.
