BS, MS, PhD
Research Clinical Psychologist
I received my PhD in clinical psychology from Northwestern University – Feinberg School of Medicine in Chicago, Illinois. I completed my clinical internship and postdoctoral fellowship at the Department of Veterans Affairs (VA) Boston Healthcare System in Boston, Massachusetts, where I worked with veterans from all eras with a range of clinical presentations and diagnoses.
Clinically, I specialized in the delivery of evidence-based treatments, including cognitive behavioral therapy (CBT). My research focused on transdiagnostic characteristics of psychiatric disorders, including emotion regulation techniques such as rumination and suppression.
I am currently the Trial Coordinator and Trial Therapist for the THRIVE trial. THRIVE aims to test virtual reality therapy for people with psychosis who find it difficult to go outside because of fear of harm from others. I am also working on the gameChange invention4innovation project, which aims to transform services for patients with psychosis by providing psychological therapies using immersive virtual reality. These projects involve collaborations with multiple NHS trusts and universities across the UK.
I am also a Trial Therapist on the Feeling Safe study, a randomised controlled trial of a novel translational psychological treatment for persecutory delusions.
I am an HCPC registered Clinical Psychologist.
