I study pulsar timing as a member of the NANOGrav Collaboration. For a primer in what we hope to accomplish, see my TEDxIthacaCollege talk: Celestial Clocks and Ripples in Spacetime!

I am interested in understanding the different processes that lead to uncertainties in our timing of pulsars. My active areas of research include:

• Understanding how the pulsar timing array works as a detector for gravitational waves
• Pulsar noise modeling, both characterization and prediction, from intrinsic pulse jitter to propagation effects
• Interstellar medium propagation effects, such as scattering, scintillation, and dispersion measure variations
