I am a theoretical physicist working on various problems in atomic and nuclear physics. My main expertise is in astrophysical and laboratory searches for variations in the fundamental constants; searches for physics beyond the Standard Model in laboratory experiments; novel atomic and nuclear clocks; precision spectroscopy of highly charged ions; and atomic many-body theory. I wrote and maintain the atomic structure code AMBiT that implements the particle-hole CI+MBPT method (configuration interaction combined with many-body perturbation theory).

My research areas include the interface between atomic and nuclear physics, including precision isotope shift studies, hyperfine structure, nuclear clocks, and electronic bridge processes in nuclei. I have research experience in atomic processes in plasmas, including dielectronic recombination, photoionisation, electron-impact ionisation, and excitation processes. I have pioneered statistical methods based on many-body quantum chaos that can be applied to complex atoms and ions in plasmas.

My research also touches on cosmology, including searches for variation in the fundamental constants in the early universe using big bang nucleosynthesis and studies of quasar absorption systems. I have also been involved in proposing novel laboratory searches for dark matter using atomic systems.
