Mary Beth Williams, professor of chemistry, is the senior associate dean for undergraduate education. This position is responsible for supervision of all aspects of the undergraduate education in the college.

Williams’ primary goals are to foster and ensure an environment of inclusive excellence and to enable the academic success of our undergraduate students. She works to use assessment data to drive continuous improvement of teaching and learning in the college, and to enhance advising and the student experience. She strives to recognize and reward faculty for excellence in the classroom, and provide them with assistance and support to improve existing or try new and innovative teaching methodologies via the Center for Excellence in Science Education.

Williams earned her Ph.D. at the University of North Carolina, where her thesis work under the direction of Royce Murray focused on the electron and mass transport dynamics in hybrid redox polyether melts. Following a post-doctoral research assistantship at Northwestern University with Joe Hupp, Williams joined the Penn State faculty in the Department of Chemistry in 2001. In addition to her research program, Williams has taught ~ 3100 students in the introductory chemistry course sequence, and served as the chemistry department graduate admissions and recruiting chair. She continues to direct the Chemistry Undergraduate Summer Research Program, with support from the National Science Foundation Research Experience for Undergraduate site and from the 3M Foundation, to bring 20 undergraduates to the department each summer for full time research. In 2009 – 2010, she was the acting associate dean for administration and planning in the college.
