DECORAH, IA (12/05/2012)(readMedia)-- Donald Lee-Brown, Luther College senior from Princeton, Ill., was one of five students selected to present their work at the 2012 Undergraduate Research Symposium in the Physical Sciences, Mathematics, and Computer Science, Nov. 2-3, at Washington University in St. Louis.

Lee-Brown said of the symposium, "It's a good experience to be with and interact with other undergraduate researchers from all the colleges that attend."

At the conference Lee-Brown presented "Identifying and Classifying Long Period Variables in the Field of Open Star Cluster M23." He described a group of variable stars that he and Luther College Professor of Physics Jeffrey Wilkerson discovered in the field of view of a star cluster (M23) in Sagittarius.

Lee-Brown, the son of Barry and Kim Lee-Brown of Princeton, is a physics and mathematics double major. He is a 2009 graduate of Illinois Mathematics and Science Academy in Aurora, Ill.

The symposium provides undergraduates in the fields of mathematics, physical sciences and computer sciences an opportunity to present their research projects and results to their peers and faculty. Every fall for more than 10 years, Washington University and the University of Chicago have alternated hosting meetings at which undergraduates present their research.

Luther College is an undergraduate liberal arts institution of 2,500 students in Decorah, Iowa.
