Hilke Schlichting's research spans all aspects of planet formation theory, extrasolar planets and solar system dynamics. She is very interested in extrasolar planets, because their diversity exemplifies the range of possible outcomes of planet formation. Her research combines observations from our solar system, which is the only place where we can examine the outcome of planet formation in detail, with the new wealth of data from extrasolar planets to shed light onto the process of planet formation and subsequent dynamical evolution
