About my research: I study binary star systems containing at least one white dwarf component. My main focus is high-precision studies of eclipsing systems, combining both high-speed photometry and high-resolution spectroscopy to determine ultra-precise fundamental parameters for both stars in the binary. The eclipsing systems also allow us to search for planets in orbit around the binary by timing the eclipses and observing any long-term trends in the eclipse arrival times. I also utilise large surveys, such as the Sloan Digital Sky Survey and the Catalina Real-time Transient Survey in order to discover new eclipsing systems. I am also searching for close binaries containing white dwarfs with more massive FGK-type main-sequence companions, since these are possible supernova Ia progenitors
