Research Focus

 

I am  a joint Oxford and Kavli student fellow at the Institute for the Physics and Mathematics of the Universe (IPMU) at the University of Tokyo. I specialise in Cosmology, mainly large scale structure. My research focuses on developing tools, namely higher order statistics (HOS) that both extract the non-Gaussian information from the matter-density field. In particular, most of my PhD work has focused on the so-called ‘marked’ power spectrum, a simple yet powerful summary statistic that enhances non-Gaussian information yield from surveys However, I also have interests in more general cosmology topics, including simulation validation, and recently radio galaxies for CMB lensing cross-correlations.

Prior to my PhD I obtained my MAst (Master's) degree in Astrophysics from the University of Cambridge, UK., and completed my bachelors in Physics at Warwick University.
