I am a Research Fellow in the Department of Epidemiology and Applied Clinical Research under the Division of Psychiatry at University College London. My research involves the examination of large datasets, chiefly using the Camden and Islington Clinical Record Interactive Search system, to explore outcomes in people who use mental health services. This work also involves developing data linkages with other sources such as hospital episode statistics and mortality registers and the application of natural language processing techniques to clinical free text.
My doctoral research was conducted under the supervision of Professor Carol Brayne and Dr. Andres Roman-Urrestarazu at the University of Cambridge. My work elucidated the socioeconomic epidemiology of substance-related disorders through the analysis of administrative and routinely collected data. Before my PhD, I worked at Avalere Health, a DC-based health policy and strategy consultancy, where my work with life science clients focused on market access and product commercialisation.
