Lars Håkan Eliasson completed his doctoral studies at Stockholm University in 1984 under the supervision of Jürgen Moser. His thesis, focused on Hamiltonian systems with Poisson commuting integrals, established the academic foundation for a career dedicated to the investigation of dynamical systems, perturbation theory, and quasiperiodic motion within the field of mathematics.
Academic Appointments
Following his doctoral work, Eliasson held a professorship at the Royal Institute of Technology in Stockholm. He later transitioned to the University of Paris VII, also known as Paris Diderot University. His tenure included affiliation with the Institut de mathématiques de Jussieu, which operates under the joint authority of the Universities Paris VI and VII alongside the CNRS. Between 2012 and 2017, he served on the editorial committee of the journal Acta Mathematica.

Eliasson centers his mathematical research on the complexities of small denominators in perturbation theory. His work involves KAM theory, multiscale analysis, and Hamiltonian partial differential equations. He has also conducted significant investigations into localization and diffusion regarding quasiperiodic Schrödinger operators. In 1998, he presented these findings as an invited speaker at the International Congress of Mathematicians in Berlin. He also spent time at the Institute for Advanced Study in both 2005 and 2012.
Professional Recognition
Throughout his career, Eliasson has been awarded several honors by mathematical societies. In 1990, the Swedish Mathematical Society presented him with the Wallenberg Prize. This was followed by the Salem Prize in 1995. Later recognition included the Eva & Lars Gårding Prize in Mathematics in 2007 and the Sophie Germain Prize in 2008. His published output includes influential papers such as his 2010 collaboration with Sergei Kuksin on KAM theory for the nonlinear Schrödinger equation.
