Research

My research is focused on radio astronomy and high-energy astrophysics. This includes astrophysical research, radio astronomical instrumentation and data processing. Particular challenges in these areas my work involves with are pushing the limits of existing observing capabilities to perform cutting-edge scientific research of astrophysical phenomena at the extreme ends of the electromagnetic spectrum.

Observations using the Very Large Array (orange) reveal the needle-like trail of pulsar J0002+6216 outside the shell of its supernova remnant, shown in image from the Canadian Galactic Plane Survey. The pulsar escaped the remnant some 5,000 years after the supernova explosion.
