Dr. Alasdair M. Goodwill is a dually registered Clinical and Forensic Psychologist with the College of Psychologists of Ontario (CPO), with over 20 years combined experience in behavioural investigative analysis, threat assessment, forensic risk assessment, and therapeutic services. He is a full-time tenured Associate Professor in the Department of Psychology at Ryerson University (Toronto, Canada). Alasdair undertook his clinical internship at the Center for Addiction and Mental Health’s (CAMH, Toronto, Canada) Sexual Behaviour Clinic (SBC) where he was responsible for forensic assessments, clinical diagnostic interviews and treatment services. He has served as the President of the Canadian Association of Threat Assessment Professionals (CATAP; 2017-2018), Vice-President (2016-2017) and on the Board of Directors from 2015 to 2018.

Alasdair is a member of the Ontario Psychological Association (OPA #20151241), the College of Psychologists of Ontario (CPO) and was a member of the Canadian Psychological Association (CPA #45804) from 2016-2019. He has also been registered as a Chartered Psychologist (CPsychol; British Psychological Society, Division of Forensic Psychology, UK; 2006 to 2018) with a specialist Forensic (Practitioner) Psychologist designation (Health Professions Council, UK; 2008-2018), Chartered Scientist (CSci; BPS Science Council, UK; 2006-2012), Associate Fellow of the British Psychological Society (AFBPsS), Fellow of the Royal Statistical Society (RSS), and a Fellow of the International Association of Investigative Psychology (F-IAIP), while he resided in the United Kingdom (approx. 1997-2009).

Dr. Goodwill completed his M.Sc. at the University of Liverpool (UK) from 1997-1998 and Ph.D. at the University of Birmingham (UK) from 2001 to 2005, where he conducted his doctoral research on “Pragmatic approaches to suspect prioritisation in criminal investigations” (i.e., behavioural investigative analysis, offender profiling, crime linkage, geographical profiling, etc.). On completion of his Ph.D. he was employed as a Lecturer (i.e., Assistant Professor rank in Canada) at the University of Birmingham from 2005-2009, eventually serving as the Course Director of the Doctorate in Forensic Psychology program from 2007-2009, before returning to Toronto to take up a tenure-track Assistant Professor position in the Department of Psychology at Ryerson University in 2009. I received tenure and was promoted to the rank of Associate Professor at Ryerson in 2012.

Alasdair is an Affiliate of the Forensic Psychology Research Centre (Ottawa, Canada), Associate Member of the Carleton Police Research Laboratory (Ottawa, Canada), an Associate Member of the Centre for Investigative and Forensic Psychology (Liverpool, UK), an Associate Member of the Centre for Critical Incident Research (Liverpool, UK), and have served as an adjunct graduate supervisor at Charité Universitätsmedizin (Berlin, Germany) and the University of Huddersfield (UK). He has also served on numerous academic journal editorial boards and published extensively in the criminological, investigative, forensic and threat assessment literature. I have also presented my research and case studies at numerous international academic and practitioner-focused conferences and invited talks.

Dr. Goodwill consults regularly with law enforcement, prison and criminal investigators (private and police) and has advised on several investigations relating to serial and individual homicide, sexual offending, violent offending, threat assessment, and risk assessment (please see c.v. for further details). Further, I have been trained on a number of threat assessment tools (e.g., HCR-20, TRAP-18 lone actor terrorism tool), risk assessment tools (e.g., STATIC-99, STABLE-2007, PCL-R) and several other investigative techniques (e.g., social media analysis, forensic linguistics, hostage negotiation).

Alasdair has a clinical practice where he provides clinical assessment and therapeutic services.
