I am a member of the Male Infertility Genetics research group investigating the role of genetic mutations in male infertility together with Prof Joris Veltman.

Our research is focused on the genetics in male infertility, a severely understudied disorder that cannot be inherited without the use of assisted reproductive technologies pointing to a role for de novo mutations. In order to study this we work closely together with Mr. Kevin McEleny in the NHS Fertility Clinic in Newcastle and Fertility clinics in Manchester and Sheffield . We have established local, national and international collaborations, and are founding members of the International Male Infertility Genomics Consortium. With funding from the Netherlands Organization for Scientific Research, the Royal Society and the Wellcome Trust we are performing large-scale genomics studies in severe male infertility, aiming to identify the underlying causes and improve diagnostics. In addition, we use genomics to study the effect of assisted reproductive technologies on the genomic health of the offspring.
