Dr Alison Trew

Biochemist, PSTT Fellow

Alison was a science researcher for nine years. After completing her first degree in Biochemistry at the University of Birmingham, she moved to the University of Leeds to study for a PhD. Here she spent 4 years researching ‘The source, transport and concentration of vitamin C in the healthy and diseased human stomach’, measuring levels of vitamin C in patients’ saliva, blood, gastric juice, stomach wall and even the colon. Alison’s work showed that high vitamin C intake could reduce the risk of gastric cancer.

Alison worked as a postdoctoral research assistant in the Department of Dermatology at the University of Newcastle upon Tyne where she investigated the loss of genetic material in different types of skin lesions including warts. She then joined a team at the University of Nottingham in the Department of Obstetrics and Gynaecology where she developed a procedure to culture 'trophoblast cells', specialised cells of the placenta that play an important role in embryo implantation in the uterus. It was hoped that this would enable scientists to investigate causes of complications of pregnancy such as pre-eclampsia. Alison returned to Leeds University and worked with a team trying to identify processes involved in producing protein plaques in the brain which are thought to cause Alzheimer’s Disease.

After leaving research and having a family, Alison trained to teach. She has taught in primary schools in Devon for nine years and now works with teachers and trainees in the South West and is developing resources for the PSTT website.
