I am a clinical trial statistician at Imperial with over 6 years of experience. I have an interest in digital mental health interventions and their evaluation. I am currently an NIHR Doctoral Fellow, my PhD is exploring how we should incorporate user engagement into the trial efficacy analysis of interventions. I hope the outputs of my research will help provide trialists with much needed guidance to help improve how we evaluate digital mental health interventions. 

I have worked on several digital health studies, both with research investigators and with a commercial company, my mhealth, who developed a suite of apps to support self-management of chronic diseases. I have been a clinical trial statistician for over 6 years, working with Imperial Clinical Trials Unit (ICTU) for the last 4 years. Before joining ICTU, in my previous clinical trial experience, I worked at IQVIA in their biostatistics department where I have worked on phase I, II and IV trials. Therapeutic areas in which I have had experience includes respiratory, rheumatology, oncology.

I received my BSc in Biomedical Sciences from the University of Brighton in 2015. After which I worked as a database administrator prior to completing an MSc in Medical Statistics from the London School of Hygiene and Tropical Medicine in 2017.

Around my role as a statistician I'm a mental health first aider for Imperial, and I am involved in the community at Imperial Clinical Trials Unit (ICTU), having given talks such as the “Stress Buster” session during Mental Health Awareness week. Outside of my role at Imperial I also work on the communications team of PSI, a professional organization that offer career training to help statistician develop their leadership and technical skills. In my role, I am responsible for the digital strategy and assessing how PSI can better engage with members in our digital outreach and communication.
