Originally from Quebec, Dr. Picard Marceau obtained his medical degree from Laval University in 1958. After a year of residency in surgery in Quebec, he continued his training at the Mayo Clinic in Minnesota (USA) from 1959 to 1965. He first completed his residency, then after two years of research, he obtained a Ph.D. from the University of Minnesota. He was a Fellow of the Canadian Medical Research Council from 1964 to 1966.
Picard Marceau began his career at Université Laval as a general surgeon at Hôpital Laval in 1965 and retired forty years later. Assistant professor in 1966, was appointed associate professor in 1970, and full professor in 1988. For many years, he assiduously and energetically accomplished a set of tasks for the benefit of the Faculty Department of Surgery with the aim of always giving more to students and to the students on the scientific and pedagogical levels. He assumed responsibilities in the clerkship program and clerkship internships of the Department of Surgery from 1970 to 1985. He was also responsible for the medical ethics courses of the Department of Surgery from 1995 to 2004 and was a member of the education the Department of Surgery of the Faculty of Medicine.
In addition to his numerous contributions to university teaching, Picard Marceau maintains an intense scientific production, as evidenced by his impressive list of more than one hundred and six publications and nine book chapters. In addition, he makes many presentations at various congresses and conferences, both in Canada and abroad. As a researcher, Professor Marceau was a pioneer in the study and treatment of morbid obesity, a disease which, at the time, was unknown, not to say denied by the majority of the population, but also and especially by medical colleagues.
This field of expertise quickly appeared to Picard Marceau in all its complexity. To know and understand this pathology, he has committed himself to a scientific collection of data as broad as possible and to a reading of all the existing literature relating to it. He was a member of the DB Brown Chair in Obesity Research from 1997 to 2005. He was also a leader in setting up a team of surgeons who developed expertise in bariatric surgery, expertise that is now recognized on an international scale. In recent years, he has been a visiting professor at Quebec and European universities, and he has collaborated on dissertations on bariatric surgery presented by the American Society for Bariatric Surgery.
