I am interestd in probing the structure and evolution of the Universe with gravitational-waves. In particular, I have performed work on a technique to constrain cosmological parameters using only the gravitational-waves emitted by inspiraling double neutron-star systems. These systems are referred to as self-calibrating standard sirens, since they constitute a cosmological distance indicator which is calibrated only by our understanding of gravitation. I have also worked on constraining the properties and nature of a stochastic gravitational-wave background by using arrays of regularly observed millisecond pulsars. These pulsars act as very stable clocks such that any background of gravitational-waves may leave a measurable and correlated imprint in the arrival times of pulses.
