Matthew is a statistical geneticist with a focus on cerebrovascular disease. After completing his PhD working on the WTCCC2 Stroke Genetics study, he undertook post-doctoral research at King’s College London and University of Cambridge before joining Queen Mary University of London as a lecturer in 2019.

Dr Traylor’s research is focused on understanding the causes of cerebrovascular disease and their impact of dementia, using genetics. Through genome-wide association meta-analyses his work has identified dozens of genetic loci associated with stroke and cerebral small vessel disease.

Memberships and awards

  • Member of the International Stroke Genetics Consortium



As a statistical geneticist, Dr Traylor works primarily on genetic studies of cerebrovascular disease.

His work focuses on several key areas:

  • Large Scale GWAS Meta-analyses of Stroke and Stroke subtypes
  • Genetic studies of MRI markers of cerebral small vessel disease
  • Understanding the causal mechanisms leading to cerebrovascular disease and dementia
  • Developing and implementing methods to tackle the challenge of stroke heterogeneity
