I'm an experimental cosmologist and long-wavelength instrumentalist, currently employed as Associate Professor at the Dunlap Institute and David A. Dunlap Department of Astronomy & Astrophysics at the University of Toronto. I'm currently actively recruiting both undergraduate and graduate students interested in cosmology and radio instrumentation.


My primary research interests span cosmology and instrumentation. I'm interested in developing new probes of Dark Energy, with a focus on mapping out the expansion history. By studying its properties and evolution, we can make firm statements about the physicals processes which must have been active. Despite -- or perhaps because of -- its size, the LSS is difficult to observe, and specialized instrument and surveys are required to study it.

I have developed and work with a variety of telescopes and radio arrays, the largest being the Canadian Hydrogen Intensity Mapping Experiment (CHIME), along with its myriad offspring (CHIME/FRB, CHIME/pulsar, CHIME/VLBI, ...); its Outrigger program for Very-Long-Baseline Interferometry (VLBI) localization of Fast Radio Bursts (FRBs); and the Canadian Hydrogen Observatory and Rapid-transient Detector (CHORD).

Farther afield I'm involved with the Hydrogen Intensity and Real-Time Analysis eXperiment (HIRAX) in South Africa, and the Chilean/Canadian Hydrogen Array for Realtime Transient Studies (CHARTS), a new array under development outside Santiago. More locally, my group makes regular forways up to Canada's recently re-commissioned Algonquin Radio Observatory (ARO).

Prior my current position, I was a postdoc in the McGill Cosmology Instrumentation Lab, working with Matt Dobbs. For most of 2008 I lived in the Antarctic as a winterover for SPT, and before that I was a graduate student at the University of Chicago. While there, I spent a lot of time time on outreach projects, particularly within the MSCOPE program, working in and developing exhibits for the Museum of Science and Industry and Adler Planetarium, some of which are still in use.

Beyond work pursuits, I enjoy fresh air & sunshine: cycling, hiking, climbing, kayaking, really anything that'll get me outside and into the world. I dabble in photography, make a mean chocolate truffle, and spend far too much time fiddling with computers.
