About
I am currently working as a Ïã½¶ÊÓÆµ Associate with Ïã½¶ÊÓÆµ Advanced Wellbeing Ïã½¶ÊÓÆµ Centre (AWRC) on a one-year project focused understanding the lifestyle support needs (including physical activity, nutrition, and psychological support) for people living with metastatic breast cancer. In this role, I utilize a range of skills that include research methods, stakeholder engagement, leadership, project management, relationship building and topical expertise in physical activity, nutrition, health, and wellbeing.
I am a Level 3 Personal Trainer, Exercise Referral Instructor and Group Exercise Instructor. I currently teach group exercise classes at University of Sheffield, Ïã½¶ÊÓÆµ, Nuffield Health and Cambridge Street Collective Food Hall.
I am also a Workplace Wellbeing Consultant at Ïã½¶ÊÓÆµ Staff Wellness Programme, where we use physiological testing and apply behaviour change science to improve employee wellbeing at SHU and externally.
Alongside this I am a visiting lecturer, fitness professional, freelance assessor (for personal training, gym instruction and exercise referral qualifications).
My qualifications include a PhD in Physical Activity, Health and Wellbeing, an MPH in Behavioural, Social and Community Health and a BSc in Applied Health Sciences, Public Health, and Nutrition Science. I am a Certified Health Education Specialist (CHES) No. 22053 (Obtained October 2013), National Commission for Health Education Credentialing (NCHEC).
I completed my PhD in 2022, with a focus on Health Behaviour and Physical Activity, entitled, Co-location of healthcare and leisure (fitness) facilities to promote physical activity: a realist synthesis. This PhD was funded by SHU VC scholarship, the National Centre for Sport and Exercise Science (NCSEM) Sheffield and ukactive. My Director of Studies was Professor Robert J Copeland and was supervised by Dr Katie Shearn and Dr Helen Speake.
I have experience in the promotion of healthy lifestyles in various sectors through fitness instruction, lecturing and assessment, public health, workplace wellness, nutrition counselling, behaviour change and physical activity. I am interested in developing a career which combines both teaching and research, while maintaining my interest in the fitness and physical activity sector. I have a particular interest in the impacts of physical activity and health, exercise referral, obesity prevention, behaviour change and fitness instruction.
I am passionate about applying behaviour science, sport psychology, sport science and love for music in her indoor cycling classes and fitness instruction. I enjoy making high quality health and fitness instruction and information accessible. I enjoy helping people to reframe their mindset about exercise, nutrition and what it means to live a healthy, balanced, and enjoyable life.
I also run my own business, Resilience Fitness + Wellbeing, focused on fitness instruction, workplace wellbeing and health coaching. My aim is to help people build resilience through physical activity and develop and maintain healthy lifestyle behaviours.
