A Brief History Of Me


NANOGrav Senior Postdoctoral Fellow
California Institute of Technology

My recent work has focused on new data-analysis advances that allow systematic differences in published solar-system ephemeris models (by JPL and IMCCE) to be bridged with a fully Basyesian scheme. I have also developed new methods to extend LIGO hierarchical population inference all the way back to progenitor conditions, allowing rigorous population demographical studies.

Caltech Postdoctoral Scholar at JPL
Jet Propulsion Laboratory

I developed new models for the spectra of gravitational-wave backgrounds that are trained on population-synthesis simulations. This allows the details of the dynamical history of massive black-hole binaries to be investigated. I also began leadership of NANOGrav's 11-year search for gravitational-waves.

October 2016 - September 2017

NASA Postdoctoral Fellow
NASA's Jet Propulsion Laboratory

My work focused on gravitational-wave astrophysics in the context of pulsar-timing and ground-based laser interferometers. I developed new algorithms to rapidly search for single sources, to map the amplitude and phase content of the background, and to mine stochastic signals for information about the astrophysical environment of massive black-hole binaries.

PhD in Astronomy
Institute of Astronomy, University of Cambridge

My graduate studies encompassed various investigations into gravitational-wave astrophysics, including cosmological-parameter inference with double neutron-star standard sirens, and mapping the nanohertz gravitational-wave sky with pulsar-timing.

Master of Physics (MPhys, First Class)
University of Oxford

My 4 years reading Physics at Oxford gave me a broad knowledge base in all areas of classical and modern physics. In my final year, I specialised in Astrophysics and Particle Physics.
