I specialize in making and analyzing full-sky, high-resolution maps from large astronomical imaging data sets. Much of my work focuses on processing infrared images from NASA's NEOWISE mission, repurposing this vast asteroid-hunting data set for astrophysics beyond the main belt. I am using NEOWISE data to search for cold nearby worlds, such as the hypothesized Planet Nine, Planet X, and other elusive neighbors to the Sun which may be impossible to find at visible wavelengths.
My work, particularly in relation to Planet Nine, has been widely featured in local, national and international media. A partial list of articles quoting or mentioning me by name is provided below. I was was also interviewed for a TV segment on San Francisco's KPIX5 (CBS), and radio segments on Bay Area stations KGO and KCBS.

I co-founded Backyard Worlds: Planet 9, a Zooniverse project consisting of an all-sky crowdsourced motion search built around my time-resolved WISE/NEOWISE coadds. Since launching in February 2017, over 100,000 citizen scientists have contributed to our total of more than 4 million classifications. Backyward Worlds now counts 40,000 registered users, and has benefited enormously from the enthusiasm and dedication of our diverse group of volunteers, some of whom have gone on to receive media recognition for their participation. Four citizen scientists are co-authors on the project's first peer-reviewed publication.
