Li Zeng is a graduate student currently in his fifth year and hails from Chongqing, China. Li is very passionate about holistic health and traditional healing. He is a practitioner of Tai Chi and specialized forms of martial arts. In conjunction with faculty member, Dimitar Sasselov, Li has created a new interactive tool to characterize and illustrate the interior structure of exoplanets. This tool, distributed at no cost to the public, is useful for observers to quickly constrain the interior structure of an exoplanet, for modelers to use in their computer simulations, and for instructors to illustrate the diversity of planetary structures in the classroom.
