Habib et al. +Vu (2026). Error quantification and comparison of binary neutron star gravitational waveforms from numerical relativity codes. Submitted to Phys. Rev. D. Phys. Rev. D 113, 10, p. 104062. arXiv:2509.23028.
Computational physicist at the University of Zurich in numerical relativity, computational astrophysics, and high-performance computing. Developing the next generation of massively parallel simulations of black holes. Also passionate about software development, design, data visualisation and teaching. I changed my last name from Fischer to Vu in 2022.
