    I carried out my PhD in the laboratory of Prof. Peter Gierschik in the German Cancer Research Centre and the University of Ulm in Germany working on G protein beta gamma subunit regulation of phospholipase C beta 2. I identified key amino acids in the pleckstrin homology (PH) domain of PLCbeta2 that were required for beta gamma subunit activation.

    I was a postdoctoral fellow in Medicine at the Joslin Diabetes Center in Boston working in the lab of Prof. Morris White. My focus was the role of insulin receptor substrate-2 (IRS2) in brain development. Together with Dr. Markus Schubert, we identified that mice lacking Irs2 had smaller brains due to defects in neuronal proliferation early in development.

    I then returned to Europe to work in the lab of Dr. Brian Hemmings at the Friedrich Miescher Institute in Basel. My focus was the inhibitor of PKB/Akt activation called carboxyl-terminal modulator protein (CTMP) and its role in vitro and in vivo. We used knockout approaches to evaluate the role of CTMP1 and CMTP2 in Akt signalling. Various aspects of PKB/Akt signalling in cancer and diabetes were also investigated during my time at the FMI.

    In 2003 I returned to Dublin to establish my own research group until the guidance of Prof. Hugh Brady and Prof. Catherine Godson at the Mater Hospital, University College Dublin. The overall focus of the group in UCD was diabetic nephropathy (DN), and I specifically adressed the role of PKB/Akt and proteins such as Gremlin, a BMP antagoinst, in mouse models of DN. We relocated to the UCD Conway Institute in August 2003 as part of the UCD Diabetes Research Centre working with colleagues on various aspects of diabetic nephropathy including the role of Irs2 in kidney development, connective tissue growth factor activation in diabetic kidney and in vivo mouse models of diabetic kidney disease.

    In September 2009 I relocated to Centre for Vision and Vascular Science (now Wellcome Wolfson Institute for Experimental Medicine, WWIEM) at Queen's University Belfast where I was appointed as Lecturer. I have trained 14 PhD students and 5 Masters students to date, and hosted over 60 undergraduates in my laboratory here in WWIEM. I am active in linking research and teaching activities, and was appointed as Associate Director of Undergraduate Education in our centre in 2016. 

    Research Statement

    I am interested in the molecular pathogenesis of diabetes-related complications in the kidney and other organs. We employ a combined molecular cell biology/mouse knockout approach to elucidating the cell signalling pathways involved in driving disease pathogenesis. My group has published extensively on the role of Gremlin1 in kidney fibrosis over the past 8 years, and we have recently extended these studies into the cancer field where we have identified Grem1 as a prognostic marker of human cancers. We have employed a drug discovery approach to identify small molecule inhibitors of Grem1 as potential novel therapeutics for the treatment of kidney fibrosis, cancer and other human diseases. I have ongoing collaborations with colleagues in UCD Dublin (Prof. John Crean, Prof. Finian Martin), UMC Utrecht (Prof. Roel Goldschmeding) and Harvard Medical School (Prof. Morris White). 




    I teach medical, dentistry and biomedical science students at all stages during their degrees. Tutorials and lectures on basic elements of cell biology, tissue biology and pathology, and medical case studies are given. I am module co-coordinator for a Year 1 medical module called Prinicples of Disease and Treatment1. I am also a Personal Portfolio tutor for first and second year medical students. My laboratory hosts undergraduate B. Med. Sci and MSc. students for research projects. I also contribute to postgraduate teaching and practical skills courses throughout the year. I have an active outreach portfolio and have visited several schools in Belfast to promote careers in science and medicine. I have active links with Diabetes UK and have met with patient research focus groups to discuss our research and it's potential impact for patients. As Associate Director of Undergraduate Education here in our centre, I coordinate all teaching requests for other academic staff, and try to match requests to people's expertise and teaching requirements. I have spent time in the China Queen's College in Shenyang, China teaching Year 2 and 3 Pharmaceutical Science students, and have also visited MBRU Medical University in Dubai regularly to teach and discuss with academic colleagues.
