Dr. Mejia is graduated with an MD and pursued MSc in Neuropsychology, just completing all academic credits. He also pursued a specialty in Psychiatry from 1991-1994. During a period of a year and a half prior to entering the specialty training, he worked as a respiratory therapist at the Pulmonary Physiology Laboratory, at the National Institute of Respiratory Diseases in Mexico City. Part of this work involved assisting Dr. Rogelio Perez Padilla to develop the first sleep laboratory of the same Institute and subsequently working as the first sleep technician in the said laboratory.
Once concluded the residency program in Psychiatry, Dr. Mejia moved to Montreal after being accepted to do a PhD in Human Genetics at McGill University In 1999, he also started a fellowship in Forensic Psychiatry at Queen’s University. Once this program was completed, Dr. Mejia returned to McGill University where he obtained PhD degree and worked for a year as an assistant professor, while developing a forensic psychiatry unit. Changes in the hospital’s budget left the project without funding and eventually resulted in moving to a new position in Alberta where he worked for approximately 4 years dedicated to child and adolescent forensic psychiatry as an assistant professor at the University of Alberta.
In 2005, Dr. Mejia became the Head of Division of Forensic Psychiatry at Western University (formerly known as University of Western Ontario). While in this position he developed the psychiatric portion of the sleep disorders clinic, which he then ran for approximately two years. In 2010 he became an associate professor and in 2014, he obtained a full time position in child and adolescent forensic psychiatry at IWK Health Centre, where he now dedicates his time to provide clinical services to children and adolescents who have faced or are at risk of confronting troubles with the law. This inevitably has a strong connection with sleep and its disorders as the basis for the development of multiple comorbid disorders. As an associate professor at Dalhousie University, Dr. Mejia teach students from undergrad to postgraduate. He also participates as a member of several research-oriented committees.
