Current research
I investigate how galaxies form, evolve, and cease forming stars—"quenching"—using observations from ALMA, MUSE, HST, LOFAR, and ASKAP. As we prepare for the SKA era, my work focuses on two scientific frontiers plus digital infrastructure.
Environmental Regulation of Star Formation
How dense environments reshape the interstellar medium. I co-lead MAUVE and lead VERTICO—using MUSE and ALMA to trace ram-pressure stripping and quantify how external pressures and stellar feedback regulate star formation down to ~50–100 parsec scales.
Evolution and Feedback in Dwarf Galaxies
Building a framework to understand how low-mass systems sustain or suppress star formation. Combining UNIONS, LSST, LOFAR, and WALLABY data to characterize the interplay between star formation, cosmic rays, and AGN activity.
Digital Infrastructure & CANFAR
At the Canadian Astronomy Data Centre, I guide the CANFAR Science Platform and lead the SKA Regional Centre Network (SRCNet)—designing the distributed network to support SKA science. The Canadian SKA Regional Centre will require infrastructure two orders of magnitude more powerful than current Canadian capacity.
My group bridges observational astrophysics and advanced data science to handle the exabyte-scale challenges of the next decade.
