### Main Focus

The detection of gravitational waves by the LIGO and Virgo
collaborations has prompted great interest from different branches of
physics. In particular, there is now an ongoing effort to apply
techniques used for calculating scattering amplitudes in quantum field
theories (QFTs) to obtaining gravitational wave observables. Unlike more
conventional post-Newtonian approaches, which give results as power
series in the speed of light, amplitudes-based methods give results as
power series in Newton's constant. The two are therefore a complement to
each other.

Having worked on QFT-based amplitudes for several
years, I am now applying my experience to this growing arena. While
considerable effort has gone into computing conservative potentials in
the non-spinning case, real-world physics includes other important
aspects – such as spin, radiation, and finite-size effects. Here there
remain conceptual challenges which I am currently engaging with. I am
also interested in applying the so-called double copy, which allows
gravitational amplitudes to be obtained as a "square" of Yang-Mills
amplitudes. As the latter are generally much easier to calculate, this
provides a useful computational shortcut.

### Curriculum Vitae

I studied Natural Sciences and Mathematics at the University of
Cambridge from 2009-2013, graduating with BA and Masters degrees. From
2013-2017 I worked at the University of Edinburgh towards my PhD, under
the supervision of Donal O'Connell. Finally, from 2017-2020 I worked as a
postdoctoral researcher at Uppsala University in Sweden, where I
collaborated closely with Henrik Johansson. Since September 2020 I have
held a joint postdoc position at both the AEI and Humboldt University.
