BA, BSW, MSc, PGDip (Psych)

Trainee Clinical Psychologist

I am currently in my third and final year of clinical psychology training.  My clinical placement this year is at a specialist mental health service for young people who have experienced sexual harm.

My first year of training included placements at a child and adolescent mental health service (CAMHS) and a forensic inpatient mental health centre.  My second year of training included placements at a memory service for older adults and a service focused on adults with learning disabilities.

Professional Interests

My work prior to clinical training was divided between frontline work and research, primarily within the fields of HIV and other blood-borne viruses, substance misuse, sexual and gender minorities, and sex work.

Before moving to the UK, I trained and practiced as a social worker in Canada.  More recently, I was a Research Associate at the British Psychological Society's Centre for Outcomes, Research & Effectiveness (CORE) within UCL's Research Department of Clinical, Education and Health Psychology.
