Overview

Matt has a background in biology and completed my PhD in molecular genetics 2017, where he primarily studied patients with autoimmune forms of neonatal diabetes (diagnosed in the first 6 months of life). Before starting his PhD Matt worked in a diagnostic genetics laboratory and was involved in the development and implementation of Next Generation Sequencing tests (targeted and whole exome) for NHS patients.

Research

Research interests

In his current work Matt continues to study patients with extreme forms of diabetes including rare genetic forms and type 1 diabetes diagnosed in the first year of life. The long-term goal of this is to identify the genetic and physiological pathways that lead to the development of type 1 diabetes, opening up new targets for prevention and treatment. He is also passionate about the translation of research into clinical practice and works closely with the diagnostic molecular genetics lab in Exeter to achieve this.

During his current fellowship, Matt is using whole genome sequencing and new and emerging genetics technologies to study patients with autoimmune diabetes, including DNA based immune phenotyping and transcriptomic studies to understand the consequences of mutations and the phenotype of type 1 diabetes diagnosed in the first year of life.  

Research projects

Current Projects:

  • Improving diagnosis in monogenic disorders of insulin secretion
  • Gene discovery in monogenic autoimmunity
  • Characterization of Extremely early-onset type 1 diabetes
  • Uncovering low-level somatic mutations in monogenic diseases
  • Immune profiling and phenotyping in rare forms of autoimmunity
