Professor Gerritsen was born and raised in the Netherlands. After receiving her MS degree in applied mathematics at the University of Delft, Gerritsen moved to the U.S. in search of hillier and sunnier places. In 1996, she received a PhD in scientific computing and computational mathematics at Stanford University. Before returning to Stanford in 2001, Gerritsen spent nearly five years in Auckland, New Zealand as a faculty member in the department of engineering science.
Currently, Gerritsen is a professor in the department of energy resources engineering at Stanford, interested in computer simulation and mathematical analysis of engineering processes, and the director of the Institute for Computational and Mathematical Engineering (http://icme.stanford.edu).
She specializes in renewable and fossil energy production. In addition, Gerritsen is active in coastal ocean dynamics and yacht design, as well as several areas in computational mathematics including search algorithm design and matrix computations.
