Dissertations of PhD Candidates
Simon Portegies Zwart obtained his PhD at Utrecht University. He held several positions at the University of Amsterdam, the University of Tokyo, Boston University and the Massachusetts Institute of Technology.
His research interests lie with Computational Gravitational Dynamics, Stellar and Binary Evolution, Galaxy Dynamics, Modeling Dense Stellar Systems, Supermassive Black Holes, Binary Population Synthesis and High-performance Computing. Portegies Zwart is part of the AMUSE (Astrophysical Multipurpose Software Environment) team. The aim of this project is to provide a software framework for astrophysical simulations in which existing codes from different domains, such as stellar dynamics, stellar evolution, hydrodynamics and radiative transfer can be easily coupled.
