Charles Hellaby is an associate professor of applied mathematics at the University of Cape Town, South Africa. He is a member of the Bahá’í Faith. His research interests include:
- Inhomogeneous cosmology. Standard cosmology assumes a smooth homogeneous universe, but the real universe is very lumpy
- Inhomogeneous cosmological models – their evolution, geometry and singularities
- Non-linear structure formation in the universe
- Extracting the geometry of the cosmos from observations
- The Lemaitre–Tolman cosmological model
- The Szekeres cosmological model
- Junction conditions in GR
- Dense black holes
- Local inhomogeneities and the Swiss cheese model
He has also worked on
- The models of Vaidya, Schwarzschild–Kruskal–Szekeres & Kinnersley
- Classical signature change
- Cosmic strings
- Gravitational collapse
