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
GOTO, a
wide-field survey telescope we have developed on La Palma and in
Australia that is searching for
electromagnetic counterparts to gravitational-wave transients.
