Fast Radio Bursts

My research focuses on uncovering the origins of FRBs using the CHIME/FRB experiment. In particular, I have led multiple campaigns to search for high-energy counterparts to FRBs, with a specific focus on associations with gamma-ray bursts (see my work here ). I am also interested in what we can learn by monitoring repeating FRBs and studying their morphology (time and frequency structure) at high time resolutions. My work on this can be found here.

CHIME/FRB Outriggers

The CHIME/FRB Outriggers is a transcontinental, very long baseline interferometry network that will greatly improve upon the localization capabilities of CHIME such we can not only localize FRBs to their host galaxies, but also pinpoint them within those galaxies (e.g., to a specific spiral arm). Over the last four years, I have led a massive campaign with the Very Long Baseline Array to obtain precise positions and proper motions for ~80 pulsars which have served as the primary check sources of the Outriggers.

The VLBA observations finished in February 2025, and I plan to publish a catalog with positions, proper motion, and parallax for these ~80 pulsars within the next year. I'm particularly excited for all of the auxilary pulsar science to come out of this work.
