Samuel Upton

Dr. Samuel Upton is a Research Fellow at the University of Southampton, specializing in theoretical physics with a focus on gravitational physics and general relativity. His primary research interests include black hole dynamics, gravitational wave modeling, and self-force calculations. He has contributed to advancements in numerical relativity and perturbation theory, particularly in developing methods for calculating gravitational self-forces in extreme mass ratio inspiral scenarios.

His work bridges mathematical physics and astrophysical applications, with a focus on high-precision modeling for gravitational wave observatories like the Laser Interferometer Space Antenna (LISA). Upton’s methodologies include spectral methods and covariant formulations to address challenges in regular gauge conditions and singular field regularization.

• Notable contributions include:
• Development of multidomain spectral techniques for self-force calculations
• Pioneering work on second-order gravitational self-force in regular gauges
• Analysis of Lorentz violation effects in high-energy dispersion relations

Upton collaborates with international teams and publishes in leading journals like Physical Review D. His research aims to improve waveform modeling accuracy for next-generation gravitational wave detectors.
