Jacques Lacroix is a professor at Department of Pediatrics, Université de Montréal. He is the director of the Clinician Investigator Program, Université de Montréal. He works in the pediatric intensive care unit (PICU) of the CHU Sainte-Justine. He created and led two specialty programs recognized by the Royal College of Physicians and Surgeons of Canada: pediatric intensive care medicine (1992-2000) and clinician investigator program (2009-2020). His main topics of research are transfusion medicine, multiple organ dysfunction syndrome and pediatric trauma. He published 315 papers (268 in peer-reviewed journals, h-index = 66, i10-index = 170, 21,486), 93 chapters, a textbook in pediatric critical care medicine (2nd edition, 1368 pages), section editions in 2 other textbooks; he also produced 207 published abstracts, and 117 unpublished posters and free papers. He gave 313 invited lectures across the world, including 165 outside Canada. He received $63 millions from academic granting agencies CIHR, British NIH, NIH, PHRC, FRSQ, etc.). He published three landmark randomized controlled trials, the TRIPICU study (N Engl J Med 2007;356:1609-19), the ABLE study (N Engl J Med 2015;372:110-8), and the ABC-PICU trial (JAMA 2019;322:2179-90). In 2002, he created with Adrienne Randolph (Harvard) the Pediatric Acute Lung Injury and Sepsis Investigators (PALISI) Network (www.palisi.org), a scientific network that included more than 90 university-affiliated North-American pediatric intensive care units. Many international organizations have sought his expertise (American NIH, British NIH, Société de réanimation de langue française, Society of Critical Care Medicine, etc.); many guidelines resulted from these scientific activities. He supervised 2 post-doctorates, 2 PhD, 30 MSc students, 30 clinical fellows, and 3 other students. He received many honors, including the Alan Ross Price (Canadian Paediatric Society, 2013), the PALISI Leadership Award (2014), the Deborah J.
