About
I am a Fellow by Examination at Magdalen College, researching radio pulsars and the interstellar medium (ISM). My particular interest is in understanding how polarized pulsar radio emission varies in both frequency and time.
I'm using the unprecedented bandwidth of the Ultra-Wideband receiver on Murriyang, the Parkes radio telescope (more details here) to study the polarization properties of a large number of pulsars. Here are the results of my study demonstrating that circular polarization is the key to understanding radio pulsar polarization. You can also click here for a paper on my methodology for aligning and visualizing broadband polarimetric observations with a detailed understanding of the effects of the ISM.
As a member of the MeerTime collaboration I'm involved in the work of the Thousand-Pulsar-Array project. This project is building a comprehensive picture of the radio pulsar population with ongoing observations of more than a thousand pulsars and more than a million individual pulses. See here for more information about this work. I have modelled the frequency-dependent scattering properties of a large survey of pulsars to reveal the structure and distribution of scattering material in the ISM. See here for a paper on the scattering properties of 84 pulsars observed with the MeerKAT L-band receiver, and here for the published scattering analysis software developed alongside this work and available for use on pulsar and Fast Radio Burst observations.
Information about the structure of the pulsar beam can also be obtained by studying the frequency-dependent behaviour of single pulses. My work comparing pulsar beam models through statistical single pulse analysis of PSR J1136+1551 can be found here.
Previously I completed my DPhil at Hertford College, University of Oxford, and my BA and MSci in Natural Sciences at the University of Cambridge, with a Masters project focused on investigating new eclipsing binaries from the NGTS survey. I've also worked on the SpaceWarps project, contributing to a publication on modelling the properties of gravitational lens candidates identified in the CFHTL Survey.
