I'm a staff astronomer at the National Radio Astronomy Observatory (NRAO) in Charlottesville, Virginia and a Research Professor in the Astronomy Dept at the University of Virginia (UVA) specializing in pulsars. I'm a founding member of the North American effort to directly detect nanoHertz gravitational waves using MSPs called NANOGrav, and am currently the Chair of the IPTA Steering Committee.
As of August 15, 2014, I'll be on sabbatical for 10 months. For the first 4, until Dec 21 (or the end of Michaelmas Term(!?)) I'll be a Visiting Fellow at All Souls College and the Dept of Physics at Oxford. As per usual, I'll be working on pulsars, but a lot of it will have to do with future telescopes like the SKA. From January-June 2015 I'll be at UC Berkeley and for the first bit will be a Visiting Miller Professor. If you need to get in touch with me, just send me an email (but be prepared to possibly wait slightly longer than you would during non-sabbatical time...).
