Prostate cancer arises from multiple complex cellular processes that remain to be fully understood. Dr Pearson’s research into prostate cancer integrates basic molecular and cellular biology with preclinical trials to advance our understanding of prostate cancer biology, and to translate laboratory studies into improvements in patient care and outcome. To address this, the research undertaken incorporates the development and application of innovative preclinical model systems in collaboration with researchers, clinicians and industry.

Education and qualifications
I am a Cancer Research UK Research Fellow at the European Cancer Stem Cell Research Centre, Cardiff University. I graduated from the University of East Anglia in 2004 with a BSc in Biochemistry, following an exchange year at Colorado University (Boulder, USA). In 2004, I undertook my PhD at Cardiff University, where I developed several new models of prostate cancer, and moved to Australia to commence my post-doctoral training at the Peter MacCallum Cancer Centre in Australia. In 2012, I became an honorary fellow of Melbourne University and the inaugural Richard Pratt Foundation Fellow for prostate cancer research. In 2016, I returned to Cardiff University as a Marie Sklodowska-Curie Actions COFUND research fellow and was awarded a Cancer Research Career Development Fellowship in 2019, enabling me to build my research group investigating the molecular mechanisms that underpin prostate cancer growth and therapeutic resistance. This knowledge is applied to the development of novel and more effective biomarkers and therapeutic approaches for prostate cancer.
