Mitchel T. Keller, assistant professor of mathematics at Morningside College, recently organized a three-part mini-symposium on the combinatorics of partially ordered sets at the Society for Industrial and Applied Mathematics (SIAM) Conference on Discrete Mathematics in Denver.

Keller, along with Stephen J. Young of Pacific Northwest National Laboratory, invited 11 others to join them in each giving 25-minute talks about their research as part of the conference. There were speakers from North America, Europe and Australia, including graduate students and senior researchers in the field.

Keller joined the faculty at Morningside College this fall after previously serving as assistant professor of mathematics at Washington and Lee University in Lexington, Va. He also served as a research assistant professor at the University of Nebraska-Lincoln and a visiting fellow at the London School of Economics and Political Science. He has a Ph.D. in mathematics from the Georgia Institute of Technology in Atlanta.
