College of Agriculture Administration 

  • Interim Dean of Ag/Prof Animal Sciences
  • Interim Dean

Animal Sciences 

  • Professor of Animal Sciences


As interim 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 role as administrator, Dr. Plaut also has an active research program in mammary gland biology.

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.
