Personal profile

Research interests

My Research interests focus on the use of genetic variation to provide insights into forensic science, genetic disease, molecular ecology and ageing. Past and current projects include the role of inbreeding and population substructure on forensic match calculations, the roles of selection and drift on rare genetic disorders, how ageing influences genetic drift and, most recently, SNP variation predicting response to chemotherapy amongst triple negative breast cancer patients.

Supervisory Interests

My supervisory interests include both in silico and in vitro explorations of how genetic information can inform our understanding of evolutionary biology and genetic health.
