Brief Bio


Dr. Ian Wong is an observational astronomer at Goddard Space Flight Center in Greenbelt, MD. As part of Dr. Stefanie Milam's team, he is involved with the JWST Solar System GTO program. Born in Irvine, CA, he graduated with a BA in Linguistics from Princeton University in 2012. Prior to becoming a NASA Postdoctoral Program Fellow at Goddard, he received a PhD in Planetary Science from Caltech in 2018 and then completed a three-year stint at MIT as a 51 Pegasi b Postdoctoral Fellow. Dr. Wong's research spans both solar system and exoplanet science, with primary interests centered on icy asteroids and exoplanet atmospheric characterization.

Research Interests


Solar System small bodies

Solar System: Solar System

Dr. Wong studies the surface composition and ensemble properties of middle and outer solar system small bodies, including Jupiter Trojans, Hildas, Kuiper belt objects, and Centaurs. Using both ground- and space-based photometry and spectroscopy, he seeks to characterize these enigmatic minor body populations in a comparative manner as a test of current solar system formation and evolution models. Recently, he has been affiliated with the science team of the NASA Lucy flyby mission to the Jupiter Trojans. In addition to contributing to the analysis of upcoming data from the JWST Solar System GTO program, Dr. Wong is Co-I on a Cycle 1 GO program that will obtain reflectance and emission spectra for all of the Lucy flyby targets in support of the spacecraft mission.


Discovery and characterization of gas giant exoplanets

Solar System: Extrasolar Planets

Dr. Wong explores the atmospheres of gas giant exoplanets using a variety of observational techniques, including transmission spectroscopy, secondary eclipse photometry, and full-orbit phase curves. By measuring the light reflected off, emitted from, or transmitted through the atmosphere, he seeks to constrain fundamental properties of the planet, such as atmospheric metallicity, molecular abundances, albedo, and temperature-pressure profiles on both local and planet-wide scales. The launch of the Transiting Exoplanet Survey Satellite (TESS) has opened a major new chapter in exoplanet science. Dr. Wong has extensively leveraged data from the spacecraft to discover new hot gas giants in the solar neighborhood and carry out systematic phase-curve studies in search of fundamental trends in dayside reflectivity and global heat transport.
