# François Lalonde

François Lalonde (17 de setembro de 1955) é um matemático canadense, especialista em topologia simplética.
Lalonde obteve o bacharelado em física em 1976 na Universidade de Montreal, e após 1 ano completou o bacharelado em matemática em 1977, com um mestrado em lógica e ciência da computação teórica em 1979. Em 1985 obteve um doutorado (Doctorat d'Etat) em matemática na Universidade Paris-Sul em Orsay, orientado por Weishu Shih. Foi depois NSERC University Research Fellow na Universidade do Quebec em Montreal, onde foi full professor de 1991 a 2001. É professor da Universidade de Montreal desde 2001, ocupando a Canada Research Chair em topologia simplética.
Foi palestrante convidado do Congresso Internacional de Matemáticos em Madrid (2006: Lagrangian submanifolds: from the local model to the cluster complex).
