Gemma is a Senior Lecturer in Psychology. She obtained a First Class BSc in Psychology (2001) and PhD in Ingestive Behaviour (part-time, 2006) from Loughborough University, before working and living overseas. Upon returning to the UK, Gemma worked as a Research Associate at Nottingham University (2009) before re-joining Loughborough University as a part-time Research Associate in 2011. After a number of part-time research and teaching positions alongside childcare, Gemma became a full-time Lecturer in Psychology in 2015 and was promoted to Senior Lecturer in 2020. Gemma lectures on the Loughborough Psychology undergraduate degree programmes where she leads The Psychology of Eating Behaviour module and the final year dissertation module, as well as teaching on modules relating to parenting and children’s socialisation and clinical psychology. Gemma supervises undergraduate and postgraduate (PhD) students’ research projects and is the founder and lead of the Gender and Sport mini-CDT; a group of 6 multi-disciplinary PhD research projects exploring the critical issue of gender identity in sport.  

Gemma has previously held the roles of Placements Co-ordinator (2016 - 2018) and Admissions Tutor (2017– 2020) and was a Warden of Cayley Hall of Residence (2014 – 2017). She is also a founding member of the Maia Network – Loughborough University’s women’s network established in 2020.

Gemma’s research activities are broad but are all linked by a focus on gender and the impact of gender on everyday psychological functioning, as well as clinical pathology. Specifically, her research focuses include body image and the impact on eating behaviour and psychopathology; post-partum and maternal wellbeing; sexuality, gender identity and mental wellbeing; transgender and non-binary participation in sport and physical activity.
