Margaret J. Geller is a Senior Scientist at the Smithsonian Astrophysical Observatory. She was a pioneer in mapping the nearby universe. Her maps provided a new view of the enormous patterns in the distribution of galaxies like the Milky Way --- the largest patterns we know.

Dr. Geller's long-range scientific goals are to discover what the universe looks like and to understand how it came to have the rich patterns we observe today. To put the pieces of this grand puzzle together she studies systems of galaxies ranging from pairs of galaxies to clusters containing thousands of objects. She has developed innovative techniques for using the data to understand the properties of these systems and their evolution throughout the history of the universe.  . . . short bio
