Tryggvason Named Interim Department Chair

Grétar Tryggvason, the Viola D. Hank Professor of Aerospace and Mechanical Gretar TryggvasonEngineering at the University of Notre Dame, has been named interim chair person of the Department of Aerospace and Mechanical Engineering following the unexpected death of the previous chair, John E. Renaud. “Even in the best of circumstances, it is difficult to fill a leadership position,” says Peter Kilpatrick, the McCloskey Dean of Engineering. “While the college and the department have been deeply affected by the untimely death of John Renaud, we must remain committed to our mission of service. Professor Tryggvason has outstanding administrative experience and will help us continue to meet the needs of our students and alumni during these trying times.”

A faculty member since August 2010, Tryggvason specializes computational fluid mechanics; multiphase and free surface flows; flows with phase change, including boiling and cavitation; multiscale modeling; renewable energy; numerical methods; and high-performance computing. He earned his doctorate from Brown University and most recently served on the faculty and in key administrative roles at the Worcester Polytechnic Institute and at the University of Michigan in Ann Arbor.

Internationally known for his contributions to computational fluid dynamics, particularly the development of methods for multiphase flows and direct numerical simulations of such flows, Tryggvason has published more than 100 journal papers, given numerous invited presentations and supervised the research of more than 20 doctoral students.

He also is a fellow of both the American Physical Society and the American Society of Mechanical Engineers and serves as the editor-in-chief of the Journal of Computational Physics.
