About the Diabetes Research Group

Playing a key role in local and global research.


The Diabetes Research Group aims to increase knowledge at the forefront of diabetes research and develop new approaches for diabetes therapy..

Members of the Diabetes Research Group (DRG) play a key role in research both locally and globally through senior positions in Diabetes UK and the EASD (European Association for the Study of Diabetes).

Professor Peter Flatt, head of research group, has been named as the leading insulin researcher in the UK, based on the significance and impact of his published research. This ranking was produced by Expertscape and published in association with Diabetes Times.

Professor Flatt has published over 500 original scientific papers in leading peer-reviewed journals and his work has been cited more than 18,500 times.

Research themes

Insulin secretion and gene therapy

Bioengineering and proteomics of candidate insulin-secreting surrogate cells suitable for unraveling the mechanisms of pancreatic beta cell function and dysfunction and paving the way for the future gene therapy of diabetes.

Antidiabetic actions of structurally modified peptides

Investigating the impact of structural modification of biologically active brain-gut peptides on the regulation of feeding, pancreatic beta cell function and anti-hyperglycaemic activity.

Discovery, targets and action of antidiabetic drugs

Characterization of novel antidiabetic agents, isolation of new compounds from natural sources, elucidation of their sites and modes of action and potential therapeutic role in promoting insulin secretion and antidiabetic actions.

Mechanisms of pancreatic beta-cell dysfunction and insulin glycation

Involvement of glucose, lipid and drug toxicity and glycation of insulin and other pancreatic beta cell proteins in insulin secretory dysfunction, insulin resistance and pathogenesis of diabetes.

Collaborations/Partners

The Diabetes Research Group has made several key research discoveries leading to development of intellectual property and a strong international patent portfolio for commercialisation through Innovation Ulster.

Diabetica Limited was formed by three academic co-founders (Profs Flatt, O’Harte and McClenaghan) to help commercialise research findings and develop new drugs. The co-founders won the prestiguous inaugural ACES Academic Enterprise Award for Innovation in Life Sciences in Stockholm in 2008.

DRG member research was acknowledged through the prestigious membership of the Royal Irish Academy, Nordisk Medal awards and RD Lawrence Lecturer and Distinguished Research Fellowship awards.

The DRG contributed two impact case studies in REF2014, including ‘Generation of peptide therapeutics for industry’ and the ‘Development and commercialisation of human clonal beta cells for end-user communities’.

Opportunities for recruitment

Opportunities exist for recruitment of a number of highly motivated research students and Fellows.

  • Overseas personnel from Bangladesh, Brazil, China, Egypt, Gambia, India, Jordan, Malaysia, Saudi Arabia and Taiwan, in addition to those from the Republic of Ireland and the UK.
  • Projects offered are in key areas of ongoing research, and provide a unique experience for innovative diabetes and biomedical training.
  • A friendly team environment exists which has previously secured 100% PhD completion within 2-4 years registration.
  • State-of-the-art equipment and expertise is available in a number of modern areas of biochemistry, cell biology, molecular biology and peptide chemistry.
  • Work is conducted in an internationally recognised research environment which places considerable emphasis on peer-reviewed publication, training and career progression.

PhD Researchers

  • Prawej Ansari

    Prawej Ansari received a B.Sc. (Hons) in Pharmacy with distinction from the International Islamic University Chittagong, Bangladesh in 2013. He was awarded a Masters of Pharmacy degree Magna Cum Laude from the North South University, Bangladesh in 2015. He is a registered Pharmacist since 2014 and worked as a Teaching and Research Assistant during his Master’s degree. He has published more than 25 journal articles and has served in the role of reviewer and editorial board member. Ansari joined the Diabetes Research Group in September 2016 as a PhD researcher. His research focuses on the isolation and characterization of phytochemicals with insulin releasing and glucose lowering effects for treatment of type-2 diabetes.

  • Sarah Craig

    Sarah, from Ballymoney in County Antrim, graduated in 2017 from Ulster University. She gained a BSc (Hons) in Biomedical Science with a Diploma in Professional Practice with first class honours. During her university course, she completed a one-year placement in Randox Laboratories where she developed a keen interest in research and development. Sarah joined the Diabetes Research group as a PhD researcher in September 2017 to work on xenin-based peptides as potential therapeutics for type 2 diabetes.

  • Ryan Lafferty

    Ryan graduated with a Master’s Degree in pharmacy in 2014, which he obtained while studying at Queen’s University Belfast. He subsequently began his pre-registration year as a pharmacist, working in a community pharmacy in West Belfast. Upon qualification, he began working as a locum-pharmacist in the greater Belfast area. His interest in diabetes was spiked after being recruited as a consultant pharmacist for a small start-up company, who developed a novel blood-glucose monitor. This experience imparted a desire to further study diabetes, resulting in the undertaking of a PhD within the Diabetes Research Group at Ulster, which he started in September 2016. He is currently investigating the therapeutic potential of a range of novel PYY peptides, with the aim of developing a hybrid peptide with several gut-hormones.

  • Dipak Sarnobat

    Dipak Sarnobat obtained BSc and MSc degrees with upper first class honours from Shivaji University, India. Later in 2014, he completed a Master’s degree in biotechnology at Ulster University. He also worked for a period in the insulin manufacturing industry. During the MSc project at Ulster, Dipak worked on the insulinotropic properties of peptides which fired his interest in diabetes research.  Dipak is currently working on a project on treatment of type 2 diabetes using genetically engineered mice to generate insulin producing cells from non-beta cell lineages.
