Margaret Geller

Research Geller is known for observational and theoretical work in cosmology and extragalactic astronomy. Her long range goals are to discover what the universe looks like and to understand how the patterns we observe today evolved. In the 1980s, she made pioneering maps of the nearby universe, which included the Great Wall and was the inspiration for Jasper Johns 2020 piece called Slice. Her SHELS (Smithsonian Hectospec Lensing Survey) project maps the distribution of dark matter in the universe. With the 6.5-m MMT, she leads a deeper survey of the middle-aged universe called HectoMAP.

Films and public lectures Geller has made several films for public education. Her 8-minute video Where the Galaxies Are (1989) was the first graphic voyage through the observed universe and was awarded a CINE Gold Eagle. A later 40-minute film, So Many Galaxies...So Little Time, contains more sophisticated prize-winning (IEEE/Siggraph) graphics and was on display at the National Air and Space Museum.

Geller has lectured extensively to public audiences around the world. She has lectured twice in the main amphitheater at the Chautauqua Institution.

She is included in NPR's list of The Best Commencement Speeches, Ever.

Her story about her entry into astrophysics and meeting the renowned astrophysicist John Archibald Wheeler, entitled "Mapping the Universe" was published by The Story Collider podcast on May 21, 2014.
