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.
My research and clinical focus is on developing effective, evidence-based cognitive behavioural therapies for patients with psychosis, anxiety, depression, and PTSD. In particular, I am interested in using virtual reality (VR) to automate the provision of CBT and enable access to effective therapies for many more people.
I have served as a trial coordinator and trial therapist for several RCTs testing VR and face to face cognitive interventions for people with persecutory delusions and agoraphobic avoidance. These projects have included collaborations with multiple NHS Trusts.
I am an HCPC registered Clinical Psychologist.
