Senior Research Software Engineer
Overview
I am a Senior Research Software Engineer (Senior Research Fellow) in the Gravity Exploration Institute of the School of Physical, Chemical, and Environmental Sciences. My work develops and supports digital infrastructure for current and future ground-based gravitational-wave observatories (LIGO, Virgo, KAGRA, Einstein Telescope). I manage the Kestrel High-Performance Computing System hosted by ARCCA for members of the International Gravitational-Wave Observatory Network (IGWN).

- software development (mainly Python, C, and C++)
- software packaging and distribution (RPM, Deb, Conda, Pip, ...)
- Optimisation
- batch software workflows with HTCondor
Biography
I completed a PhD here in Cardiff in 2013, working under Dr (now Prof) Steve Fairhurst on gravitational-wave data analysis methods.
I then moved to Louisiana State University and worked as a Postdoctoral Researcher for the 'LIGO Data Grid', providing software support for the LIGO gravitational-wave detectors. During this time I was moslty in residence at the LIGO Livingston Observatory.
I returned to Cardiff in 2017 as a Sêr Cymru Research Fellow, working on research software in the Cardiff Gravity Exploration Institute.
In 2020 I briefly took on a role as a Research Software Engineer as part of the Supercomputing Wales project, before moving into my current role as a Senior Research Software Engineer.
