Dr Jennifer Barrett is a Lecturer in Physical Activity and Exercise Physiology at Liverpool John Moores University (LJMU). She is a member of the Cellular and Molecular Physiology for Life-long Health Research Group within the Research Institute for Sport and Exercise Sciences (RISES). Her research encompasses Exercise Metabolism and Nutrition investigating mechanisms of insulin resistance. Jen completed an undergraduate degree in Sport and Exercise Science in 2017 and went onto studying an MSc in Exercise Physiology (2017-2018). She followed this on with her PhD in Exercise Metabolism and Nutrition, successfully completing in 2023. After undergoing 2 post-doctoral positions, Jen secured her lecturing position at LJMU. Alongside this, she holds an honorary research fellow position at University of Liverpool where she contributes to researching nutritional interventions prior to colorectal surgery in cancer patients to improve post-operative outcomes.

Public talk or lecture, Primary school children, Orangiser and speaker, Alfreton Primary School Visit, Pupils from Alfreton primary school attended the laboratories at LJMU to observe physiology testing and hear from 2 researchers on sport science and university.. 2023
Public consultation, Local adults, Organiser, Novotel Hotel, Hospitality workers health day, During my PhD I organised and led health assessment day at Novotel hotel. This event focussed specifically for hospitality workers within the Liverpool region. I brought together many experts from our department to provide a free health check to any individual that worked in hospitality. This included plasma glucose and cholesterol testing, blood pressure assessments, body composition measures and physical activity advice. I also organised experts Dr Sam Shepherd and Dr Joe Maxwell to give a talk on nutrition and cardiovascular disease.. 2020
