(adsbygoogle = window.adsbygoogle || []).push({});after-content-x4Lalonde received from the Universit\u00e9 de Montr\u00e9al in 1976, at the age of 20, his bachelor’s degree (called licence in France) in physics and, after a year to complete the bachelor in mathematics in 1977, he received in 1979 his master’s degree in logic and theoretical computer science (complexity theory and NP-completeness). In  1985 he received his doctorate (Doctorat d’Etat) in mathematics from the Universit\u00e9 de Paris-Saclay in Orsay[1] becoming one of the rare candidates obtaining the Doctorat d’Etat before the age of thirty. He then was an NSERC (Natural Sciences and Engineering Research Council of Canada) University Research Fellow at Universit\u00e9 du Qu\u00e9bec \u00e0 Montr\u00e9al where he became, six years later, full professor in 1991 until 2000. He is professor at the Universit\u00e9 de Montr\u00e9al since 2000, holding from 2001 to 2022 the Canada Research Chair (CRC) in differential geometry and topology when the CRC program was first set up by the Prime Minister of Canada.[2]He has held invited positions at many institutions, including the IHES (1983\u20131985), Harvard University (1989\u20131990), the Universit\u00e9 de Strasbourg (1990), the University of Tel Aviv (1997 and 1999), the \u00c9cole Polytechnique (2001-2002), Stanford University (2005 and 2022), the \u00c9cole Normale Sup\u00e9rieure de Lyon (2008), and the Universit\u00e9 d’Aix-Marseille (2015).[2]With Octav Cornea he developed a new homology (cluster homology), leading to a new universal Floer homology for pairs of Lagrangian submanifolds of a symplectic manifold.[3] He has also collaborated with Dusa McDuff and Leonid Polterovich.He became Fellow of the Royal Society of Canada in 1997 at the age of 41,  Fellow of the Fields Institute in 2001 when this distinction was introduced. From 2000 to 2002 he was a Killam Fellow, a private-public foundation in arts and sciences that enables Canadian researchers to devote most of their time to their works.       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4From 2004 to 2008 and from 2011 to 2013 he was the director of the Centre de Recherches Math\u00e9matiques (CRM), the premier scientific institute in Canada founded in 1968, based at Universit\u00e9 de Montr\u00e9al. Members of this institute have won the “Nobel Prize” in computer sciences (Turing Prize, Yoshua Bengio) in 2019 and the Wolf Prize in physics in 2018 (Gilles Brassard), considered as the most prestigious prize in physics after the Nobel, leading usually to the Nobel prize in physics. In 2022, James Maynard (Oxford) was awarded the Fields Medal after his postdoctoral year in the CRM-ISM postdoctoral program that Lalonde founded.He (co)founded several institutions, namely the Institut des Sciences Math\u00e9matiques (ISM) (McGill, Montr\u00e9al, UQAM, Concordia, Laval, Sherbrooke universities) based at UQAM, the first unified doctoral school in the world with 250 professors, the Centre interuniversitaire de recherches en g\u00e9om\u00e9trie diff\u00e9rentielle et en topologie (CIRGET), the Institut transdisciplinaire de recherches en informatique quantique (INTRIQ) with Gilles Brassard and Michael Hilke, the Unit\u00e9 mixte internationale (UMI), a joint venture between the CNRS (France) and the Centre de recherches math\u00e9matiques (CRM), and the journal Annales math\u00e9matiques du Qu\u00e9bec (Springer).In 2005 and in 2022, he was the Stanford Distinguished Lecturer. He was the Andreas Floer Memorial Lecturer (UC Berkeley) in 2005. In 2006 he was an Invited Speaker with talk Lagrangian submanifolds: from the local model to the cluster complex at the International Congress of Mathematicians (ICM) in Madrid.Selected publications[edit]with Octav Cornea: Cluster homology, ArXiv Math.SG\/0508345, 56 pages, 2006with Dusa McDuff and Leonid Polterovich: Topological rigidity of Hamiltonian loops and quantum homology, Inventiones Mathematicae, vol. 135, 1999, pp.\u00a0369\u2013385with Leonid Polterovich: Symplectic diffeomorphisms as isometries of Hofer’s norm, Topology, vol. 36, 1997, pp. 711-728with McDuff: The geometry of symplectic energy, Annals of Mathematics, vol. 141, 1995, pp. 349\u2013371with McDuff: Hofer’s L\u221e{displaystyle L^{infty }}-geometry: energy and stability of Hamiltonian flows, Inventiones Mathematicae, vol. 122, 1995, parts 1,2, pp. 1\u201334, 35\u201369with McDuff: J-holomorphic curves and the classification of rational and ruled symplectic 4-manifolds, in C.
