Forensic Science

Alec Jeffreys Forensic Genomics Unit

Recent developments in DNA sequencing technologies have revolutionised biology and medicine, and are now doing the same for forensic science. Massively parallel sequencing (MPS; also known as next-generation sequencing - NGS) allows much more information to be extracted from trace and damaged DNA samples, and will facilitate at-scene DNA analysis. The aim of the Alec Jeffreys Forensic Genomics Unit (based in the Department of Genetics and Genome Biology) is to be a UK centre for excellence in developing and applying MPS approaches to forensically relevant problems, including human individual identification, human population structure analysis and databasing, analysis of challenging trace materials, and animal species and individual identification.

We also have expertise in conventional capillary-electrophoresis-based short-tandem repeat (STR) typing, producing data for databases for the UK, Saudi Arabia and Kenya, and contributing to the UK Forensic Science Regulator’s 2021 Guidelines on Y-STRs. Our work underpins impact case studies submitted to the Research Excellence Framework (REF) in both 2014 and 2021, and we have provided specialist casework for the East Midlands Special Operations Unit and Hampshire Police, among others.

We are honoured that Professor Sir Alec Jeffreys, who pioneered the entire field of forensic genetics back in the 1980s, has allowed us to associate his name with our unit.
