Dr. Gottschalk was born and raised in Buenos Aires, Argentina, where he obtained a DVM. He then arrived to Canada in 1987 where he obtained his PhD in microbiology and immunology from the Faculty of Medicine of the University of Montreal. Since 2002 he is full professor at the department of pathology and microbiology of the Faculty of Veterinary Medicine of the University of Montreal. He obtained six different national awards for his research. In addition, he was granted with an Honoris Causa by the University of Ghent (Belgium) in 2018 as a recognition for his career. Dr. Gottschak is the director of the international reference laboratory for swine pleuropneumonia (caused by Actinobacillus pleuropneumoniae) and the international reference laboratory for Streptococcus suis, and important swine and human pathogen. He is also a consultant for the WHO on human disease caused by S. suis and he is frequently requested for his expertise to act on human outbreaks in Asia. Dr. Gottschalk has published more than 400 articles in peer-reviewed journals and around 150 articles in professional journals. He has been requested as invited speaker to give more than 300 conferences in more than 35 countries around the world.
