Karen I Plaut

College of Agriculture Administration 

  • Dean of Ag/Prof Animal Sciences

Animal Sciences 

  • Professor of Animal Sciences


As dean, Dr. Plaut is responsible for administering academic programs in the College of Agriculture, the Indiana Agricultural Experiment Station, the Purdue Cooperative Extension Service and a number of state regulatory services. In addition to her administrative role, Dr. Plaut is also Professor of Animal Sciences and has an active research program in mammary gland biology. Prior to her appointment as dean, she was Senior Associate Dean for Research and Faculty Affairs in the College of Agriculture.

Dr. Plaut received her B.S. in animal science from the University of Vermont, an M.S. in animal nutrition from Pennsylvania State University and a Ph.D. in animal science from Cornell University.  Her postdoctoral studies were completed at the National Cancer Institute at NIH.  Before coming to Purdue she was on faculty at the University of Vermont and Michigan State University serving as Chair of the Department of Animal Sciences at both institutions.  She also spent a few years working with NASA as Lead Scientist for the International Space Station.
