Gerald Holder

Dean Emeritus

overview

For two decades as U.S. Steel Dean of Engineering at the Swanson School of Engineering, Gerald D. Holder led its growth as one of the top 25 public engineering programs.

Dean Emeritus Holder earned his bachelor’s in chemistry from Kalamazoo College, and his bachelor’s, master’s and PhD in chemical engineering from the University of Michigan. His research focus area is the phase behavior of natural gases & petroleum with emphasis on natural gas hydrates. He joined the chemical engineering faculty at Columbia University in New York City in 1976 and served in that capacity until 1979, when he came to the University of Pittsburgh. He served as Chair of Chemical Engineering from 1987-95 and became Dean of Engineering in 1996. In these leadership roles, Dean Holder fostered the development of programs in bioengineering, polymers, environment and energy, manufacturing, and materials.

At Pitt, he has received awards for his research and teaching, including the School of Engineering Award for Outstanding Research and the Board of Visitors Faculty Award. His regional and national accomplishments include the William Metcalf Award for Lifetime Achievement in Engineering from the Engineering Society of Western Pennsylvania; Fellow of the American Institute of Chemical Engineers (AIChE), the American Association for the Advancement of Science, and the Oak Ridge Associated Universities; and a General Motors Scholar.

To mark his 20th anniversary as Dean of the Swanson School, Provost Patricia Beeson appointed him as a Distinguished Service Professor, a title that recognizes distinctive contributions and outstanding service (e.g., professional, regional, national, international) to the University community in support of its multifaceted teaching/research/service mission, as well as performance excellence and national stature in his discipline.
