Experience
Small Bodies Exploration Missions: Co-I of Dawn mission Ceres extended phase, core science team member of Deep Impact, Deep Impact eXtended Investigation (DIXI), Stardust-NExT, Dawn, OSIRIS-REx, leading photometry related mission science operations and scientific data analysis, participating in science opportunity identification and study, observing sequence design and planning, ground-based observing campaigns.
Photometry of Planetary Surface: Disk-resolved photometric modeling of about ten planetary bodies, including mostly cometary nuclei and asteroids that have been imaged by spacecraft from flybys or rendezvous, as well as Hubble Space Telescope and ground-based imaging data.
Planetary Defense: Core member of the DART Investigation Team, leading the Hubble Space Telescope observations during and after the impact as an essential component of global observing campaign to bridge the impact process and kinetic impact momentum transfer. These observations also contribute to the study of active asteroids and natural asteroid impact.
Thermophysical Modeling: Spatially resolved thermal physical modeling of Ceres from sub-millimeter interferometer data.
High-Contrast Imaging and Space-based Interferometry: High-contrast imaging observations with adaptive optics to search for companions near asteroids and close companions near stars. Conceptual studies of the applications of interferometric techniques in planetary sciences, especially for outer solar system objects.
Data Archiving: Highly experienced data provider and reviewer for the NASA Planetary Data System, particularly the Small Bodies data, both for exploration mission data and ground-based data. Deep understanding of the standard, organization, and workflow of long-term data archiving.
