Profile

I am a Lecturer and Winton Fellow at Queen Mary University of London. My research focuses on understanding the evolution, diversity and habitability of planetary systems, which I pursue using a variety of ground- and space-based observatories.

I completed my PhD at the University of Oxford in 2015, where I worked on young eclipsing binary stars and their environments in open clusters. Following my PhD, I moved into exoplanet research and took up a postdoctoral position in exoplanets at the University of Cambridge. In 2018, I was awarded a Winton Exoplanet Fellowship, which I also held at Cambridge. I moved to QMUL in May 2020 to join the Astronomy Unit as a lecturer.

Research

Research Interests:

My primary research interests focus on understanding the evolution, diversity and habitability of planetary systems. Within these overarching themes, some areas of particular interest include:

  • Characterising transiting exoplanet systems at different ages throughout their lifetime. Young planets (i.e. those less than around a billion years old) are especially interesting, as they offer direct observational link between our theories of planet formation and the currently known, old, exoplanet population.
  • Observationally calibrating stellar (and hence planetary) evolution theory using various complementary approaches:
    • Characterising eclipsing binary stars, for which the stellar masses, radii and temperatures can be directly measured.
    • Characterising stellar rotation and flare activity, which offer insight into the age-activity-rotation relation.
    • Studying the star-disk interaction, which provides a window onto the final stages of star formation and the inner regions of protoplanetary disks.
  • Assessing the potential habitability of exoplanet systems by characterising the high energy activity of low-mass stars.

Funding

I am currently supported by a Winton Exoplanet Fellowship.
