Gretar Tryggvason is Department Head of Mechanical Engineering[1] and Charles A. Miller Jr.
Distinguished Professor at Johns Hopkins University.
Tryggvason was the editor-in-chief of Journal of Computational Physics[3] from 2002–2015.
Tryggvason has been a leading worker computational fluid dynamics and numerical methods.
For simulating multiphase flows, he and his co-workers have developed a front tracking method that incorporates an unstructured, moving grid within an underlying Eulerian grid.
