Welcome to Paul Lasky's home on the web

I am a lecturer in the Monash Centre for Astrophysics (MoCA), at Monash University in Australia. I am interested in a number of topics under the broad heading of gravitational astrophysics, although I have a particular penchant for gravitational wave astrophysics. I am a member of the LIGO Scientific Collaboration and the Parkes Pulsar Timing Array (PPTA), which are two complementary experiments at the forefront of gravitational wave research.

  • November 1, 2016: I was awarded a Future Fellowship by the Australian Research Council which provides funding for the next four years. My project is worth $652,000, and is entitled 'extreme astrophysics in the age of gravitational waves' The official project abstract reads: This project aims to probe the most catastrophic explosions in the universe. It will use gravitational wave astronomy to detect an exotic effect that causes space to permanently deform following cataclysmic events, determine the origin of binary black holes by measuring statistical properties of many mergers, and use observations of colliding neutron stars to understand the physics of the biggest explosions in the Universe. This project will lay the framework for the next decade of the new field of gravitational-wave astronomy.
