Frank T. Keimig Climate System Research Center Department of Geosciences University of Massachusetts Amherst, Ma 01003-5820 Phone: 413-545-0659 Fax: 413-545-1200 frank@geo.umass.edu

Frank Keimig received a B.S. in mathematics from St. Peter's College, New Jersey, an M.S. in mathematics from the University of Notre Dame, Indiana, and an M.S. in Meteorology from Rutgers University, New Jersey.

Frank taught high school mathematics and worked in application systems development for the Prudential Insurance Company prior to coming to UMASS in 1990.

Frank is the manager of the Climate System Research Center, supporting the climatological research efforts of Professor Raymond S. Bradley and several post-doctoral associates and graduate students through programming, data analysis, and graphics. He also has responsibility for maintaining all hardware and software in the lab.

Frank is an Adjunct Lecturer in the Department of Geosciences and teaches the Climatology course.
