Margaret Westwater


I am a PhD student working under the supervision of Prof. Paul Fletcher as a part of the NIH-Oxford Cambridge Scholars Programme. My research training began as an undergraduate Neuroscience major at George Mason University, where I assisted functional MRI research of stress and cue reactivity in women with bulimia nervosa. Prior to undertaking my PhD, I completed an MPhil in Medical Science (Psychiatry) with Prof Fletcher, and I examined the combined effects of age and body mass on cortical thickness in overweight adolescents and adults. Currently, I am using multimodal neuroimaging and integrative physiology techniques to assess the role of gut hormones, brain structure and cognition in patients who suffer with binge eating.
