Dr Chris StevensOffice: 310A
My research lies in the field of mathematical and computational relativity. I am particularly interested in:
- Black holes and gravitational waves
- Initial boundary value problems for Einstein’s field equations
- Cauchy-characteristic matching and characteristic extraction
- The conformal field equations and global properties of space-times
- Conformal Cyclic Cosmology
I have multiple student projects available; if you are interested in doing a fourth-year project, MSc. or Ph.D. related to any of the above fields feel free to send me an email, or stop by my office to discuss the possibilities.
