We search for and spectroscopically characterize the coldest T- and Y-type brown dwarfs through our collaboration with Backyard Worlds: Planet 9; and investigate atmospheric phenomenon, including clouds to chemistry, using facilities such as IRTF, Lick and Keck observatories (read more...)

We help characterize the coldest host stars of newly discovered exoplanet systems in collaboration with the SPECULOOS consortium, including the TRAPPIST-1 and LP 890-9 systems (read more...).

With thousands of ultracool stars and brown dwarfs being found, we are building methods of using this population to study the Milky Way at large, through deep imaging and spectroscopic surveys, machine-learning approaches to sample construction, and population synthesis simulations (read more...).

Binary and higher-order multiples are important laboratories for studying the physical and evolutionary properties of cool stars and brown dwarfs. We deploy various methods to find and characterize cool pairs, including adaptive optics imaging, high resolution spectroscopy, high-precision astrometry, and spectral blend methods (read more...).

Cool stars and brown dwarfs are surprising active! We investigate emission mechanisms in the radio, optical, and X-ray, and try to understand why some ultracool dwarfs are just rambunctious (read more...).

Our team fully support open data practices, and we maintain a large repository of low-resolution near-infrared spectra of ultracool dwarfs in the SpeX Prism Library (SPL) and SPL Analysis Toolkit (SPLAT). We are currently reducing 20+ years of IRTF/SpeX data through a NASA ADAP program for public release (read more...).

We investigate best practices in astronomy and physics education in informal, undergraduate, and graduate levels, with a particular focus on video lectures, team- and project-based learning, and engaging with the scientific literature (read more...).

Through our Project Planetaria and cosmOcosm collaborations, we explore the intersection of art and science through immersive and interactive environments, embodied physics, and data-driven art design (read more...).

Our team researches, teaches, organizes, and advocates to address social inequities in the physical sciences tied to sexism, racism, ableism, and other discriminatory practices embedded in Western science culture (read more...).
