Olga is an Experimental Psychologist studying judgement and decision making. Her main focus is the application of Psychology theory, evidence and experimental methods to the study of medical decisions. She has conducted research on professional judgement and decision making in a variety of healthcare contexts, including dentistry, neonatal and adult intensive care, surgery, and primary care. As Principal Investigator and Co-investigator, she has obtained funding from the Department of Health, Cancer Research UK, and the European Commission for studies in diagnosis, diagnostic error, decision support, and referral decision making.
Olga is the current President of the Society for Medical Decision Making (SMDM). She has served as elected Trustee on the SMDM Board (2013-2016); organised and chaired the 16th biennial European SMDM meeting (London, 12-14 June, 2016); and is Associate Editor of the journals Medical Decision Making and MDM Policy & Practice.
