Man Hoi Lee is a planetary dynamicist who works on the formation and dynamical evolution of planetary bodies (planets, moons, etc.) in our Solar System and in planetary systems around other stars. His research interests include extrasolar planets in or near orbital resonances, circumbinary planets, the satellite systems of Jupiter and Pluto, and the obliquities of the giant planets in our Solar System. He is also an expert in numerical methods for dynamical simulations of planetary systems, and is the co-author of the widely used symplectic integrator SyMBA.
