Professional Information

My research interests include

• high-precision pulsar timing, pulsar timing arrays, and low-frequency gravitational radiation;
• radio polarimetry, single-pulse studies, and the pulsar emission mechanism;
• the galactic magnetic field and pulsar Faraday rotation measurement;
• interstellar scintillation and the cyclostationary statistics of the electromagnetic radiation from pulsars; and
• instrumentation and software, particularly digital signal processing on multi-core architectures.
