My primary research interests are in the field of close binary stars,
in which at least one stellar component is a white dwarf, neutron star
or black hole. This work has led me and my collaborators to develop a
series of high-speed cameras,
ULTRACAM,
ULTRASPEC and
HiPERCAM, as well as a robotic telescope on La
Palma,
pt5m. I am also interested in observing
gravitational-wave sources in the Universe discovered by the
LIGO Scientific
Collaboration, most likely emitted by close binary stars. My
effort in this area is currently focused on the construction of
GOTO, a
wide-field survey telescope on La Palma that will search for
electromagnetic counterparts to gravitational-wave transients.
