My main research focus is on observations of radio pulsars, especially the areas of data analysis and instrumentation. High-precision timing of millisecond pulsars gives us a unique "laboratory" for fundamental physics and astrophysics, including tests of general relativity and potential use as a very low frequency (nHz) gravitational wave detector. I am involved in designing and building specialized instrumentation for pulsar observations, with the goal of obtaining the best possible timing precision. I am also exploring new methods for characterizing and compensating for the effect of the interstellar medium (ISM) on the pulsar signals. In addition to improving timing results, this research provides a unique view on the structure of the ionized ISM present in our galaxy.
