Buschiazzo holds a BSc degree in Biology (Universidad de La Plata, Argentina), and a PhD degree in Chemistry (1999, Institute Leloir, Universidad de Buenos Aires). He later specialized in protein crystallography as a postdoc at the Institut Pasteur (IP) in Paris (Department of Structural Biology and Chemistry), where he obtained a tenured position in 2003. Since 2006 he has been head of the Lab of Molecular and Structural Microbiology at IP Montevideo (a member of the IP International Network) in Uruguay. Maintaining this double appointment, in 2016 he was promoted to associate professor in the Department of Microbiology (IP, Paris). His science is focused on microbiology, aimed at understanding molecular mechanisms of key proteins. A special interest is dedicated to pathogenicity determinants in Leptospira and other bacterial pathogens. Buschiazzo leads a team with strong expertise in the structural biology and biochemistry of bacterial signaling systems. His lab has uncovered how proteins change their shape and conformation in very specific ways, enabling bacteria to sense their environment and internal milieu, and trigger adaptive responses.
