Astronomer Scott Ransom works on a wide variety of projects that involve finding, timing and exploiting pulsars of various types, using data from many different instruments and at energies from radio waves to gamma-rays.

His main focus is searching for exotic pulsar systems such as millisecond pulsars and binaries. Once these pulsars are identified, he uses them as tools to probe a variety of basic physics, including tests of general relativity; the emission of gravitational waves (and hopefully soon their direct detection, as part of the NANOGrav collaboration); and the physics of matter at supra-nuclear densities. Much of his time is spent working on the state-of-the-art signal-processing instrumentation, high-performance computing and software that pulsar astronomy requires.
