Profile Introduction

The Hunter lab studies the mechanism and regulation of homologous recombination, an essential DNA-repair process required for genome stability and accurate chromosome segregation during meiosis.


1996 PhD Genetics Wolfson College, Oxford University, Oxford (UK)
1992 BS Biochemistry and Applied Molecular Biology University of Manchester (UK)

Research Contribution

Homologous recombination is an essential DNA repair process that preserves genome integrity, facilitates chromosome segregation during meiosis and generates diversity by mixing parental alleles. Defective recombination is associated with cancer, infertility, pregnancy miscarriage and birth defects.

Research Interests

Homologous Recombination.

The mechanism and regulation of chromosome repair by homologous recombination and its role in chromosome transmission and genome stability.

Post-Translational Protein Modification in Meiosis.

The nature and function of post-translational modifications of proteins involved in chromosome metabolism during meiosis.
