Exoplanets are extremely faint compared to their host stars, so how to find them? Our group uses multiple indirect methods to detect and characterize planets around stars other than our Sun, including microlensing, transit, radial velocity, and astrometry. The same methods are also used to detect and characterize other faint and/or objects, such as stellar remnants, brown dwarfs, etc.

Individual detection techniques have their own limitations, so how to combine them and derive the intrinsic distribution of planets across the whole parameter space? Our team models the observational bias and survey incompleteness and recovers the underlying planet distribution, especially key questions related to planet multiplicity. We then use these results to test and constrain the theoretical models of planet formation.
