I primarily work on the direct detection of gravitational waves using data . Most of the work is related to the analysis of the data, searching for weak signals buried in the noise of the detector noise. As part of this, I direct the Einstein@Home project, which uses idle computer cycles donated by more than 400,000 people worldwide, for searches where the sensitivity is limited by computer power. Einstein@Home also searches for weak signals from radio and gamma ray pulsars, and has found more than fifty such pulsars in data from the Arecibo Radio Telescope and the Large Area gamma-ray Telescope on board NASA’s Fermi satellite
