Personal profile


I am an early-career clinical researcher and Chief Investigator of the TASK-I RCT (Treating Anxiety after StroKe). I work with a multidisciplinary team of clinicians and academics in collaboration with data scientists and informatics specialists at the University of Edinburgh, Scotland. I was awarded the Chief Scientist Office of Scotland Clinical Academic Fellowship (PhD completed 2019), during which I led a programme of research on anxiety subtyping after stroke, leading to the development and pilot testing of a telemedicine guided self-help intervention for anxiety after stroke (TASK-CBT) in a randomised controlled trial (TASK-RCT).
I have ongoing interests in applying evidence-based innovative digital technology to improve stroke care, empower stroke patients, and expedite the generation of robust evidence through efficient and high-quality clinical trials.  
My ongoing work includes developing an automated conversational agent for stroke patients, using actigraphy as clinical outcome measure in stroke trials, efficient digitised clinical trial design e.g. TASK-II RCT, and designing digital therapeutics for stroke patients e.g. TASK-CBT, self-management app. 

I was awarded a small grant from the Royal College of Physicians of Edinburgh Lindsay Bequest & Reid Trust Research Grant to complete pilot study of using wrist-worn actigraphy sensors to collect objective stroke outcomes in a randomised controlled trial. http://www.rcpe.ac.uk/college/lindsay-bequest-and-reid-trust.
