## Biography

Gretar Tryggvason is the Viola D. Hank Professor of Aerospace and Mechanical Engineering Department at the University of Notre Dame. He moved from the Worcester Polytechnic Institute, where he was the Head of the Department of Mechanical Engineering, in 2010. Tryggvason received his doctorate from Brown University in 1985 and spent a year as a postdoctoral researcher at the Courant Institute. After fifteen years as a professor of Mechanical Engineering and Applied Mechanics at the University of Michigan, he moved to WPI in 2000. He has also held short term visiting positions at Caltech, NASA Lewis Engineering Research Center, University of Marseilles, and University of Paris VI. Professor Tryggvason is well known for his research on numerical simulations of multiphase and free-surface flows, vortex flows, and flows with phase changes. He is an active member of several professional societies, a fellow of the American Physical Society and the American Society of Mechanical Engineers, and the editor-in-chief of the Journal of Computational Physics.
