Brief Biography

I received a medical degree from the University of Glasgow in 1995 and from 1996-2000 I was a post-doctoral fellow at the University of Toronto. From 2000-2001 I was a Research Associate at The Centre  for Applied Genomics at Sickkids. In 2001, I become a Scientist in Genetics and Genome Biology and in 2008 I was promoted to Senior Scientist.

Research Interests

My interests focus on human genetics. Specifically, we work on the identification of genetic risk factors for complications of type 1 diabetes - specifically eye and renal disease. We have been using clinical data and genetic material from individuals who participated in the Diabetes Control and Complications Trial, a very important clinical trial in type 1 diabetes to identify genetic variations that are associated with the risk of eye and kidney disease. In addition, we are using data from the same individuals to identify genetic factors that are associated with the major risk factors for these diseases, including blood glucose level and blood pressure.

Our future plans are to continue the understanding of the genetic basis of both the risk factors for diabetes complications as well as the complications themselves, with the goal of understanding the mechanisms involved. Identification of novel mechanisms could result in improved screening, as well as new treatments.

We also work on a number of other, mostly common diseases.

Research Activities

Type 1 diabetes (previously called insulin-dependent diabetes) is a common complex disease defined by absence of insulin secretion from B-cells in the pancreas. Persons with type 1 diabetes require life-long insulin to survive. Living with mildly elevated blood glucose for decades results in complications which include damage to the eyes, blood vessels and kidneys. The onset of type 1 diabetes occurs commonly in childhood or early adulthood and the lifetime risk in Caucasians is approximately 1:300. The pathogenesis of type 1 diabetes is thought to be predominantly autoimmune in nature.

Genetic factors are important in the etiology of type 1 diabetes, as shown by twin, family and molecular studies. Identical co-twins of persons with type 1 diabetes have a 70 per cent chance of being affected by 35 years of age. Fraternal (i.e. non-identical) twins of persons with type 1 diabetes have a 13 per cent risk to develop type 1 diabetes, similar to the risk to siblings. Family studies show that type 1 diabetes clusters in families. Molecular genetic studies have shown linkage and association of variations in specific genes with type 1 diabetes: class II HLA loci on the short arm of chromosome 6, and a complex repetitive polymorphism near the insulin gene on the short arm of chromosome 11. However, variation in these two genes accounts for only a half of the genetic effects - it is thought there are over 20 additional genes in which variation alters a person's susceptibility to type 1 diabetes. We are using a number of strategies to attempt to identify these additional susceptibility loci.

Future Research Interests

Future projects include genetic studies of type 1 diabetes using families from the Canadian province of Newfoundland. Also we will be performing genetic studies of type 1 diabetes and specific diabetic complications, specifically retinopathy, nephropathy and cardiovascular disease, using families that participated in the Diabetes Control and Complications Trial (DCCT, now called the Epidemiology of Diabetes Interventions and Complications, EDIC).
