How do galaxies evolve? is the question at the heart of my research. In search of answers, I examine the relationships between the gas in galaxies - as the fuel for forming new stars - and their stellar, star formation, and chemical properties. My specialism lies in the analysis of large multi-wavelength datasets in order to understand galaxy populations as a whole.

I lead VERTICO, the Virgo Environment Traced in CO survey, an ongoing ALMA Large Program that is investigating the effect of extreme environments on galaxies by mapping the star-forming molecular gas in 51 galaxies in our nearest galaxy cluster, Virgo. VERTICO is the first ever Canadian-led ALMA Large Program and our team is made up of world-class researchers from all over the world who are working to reveal the physical mechanisms that drive galaxy evolution in dense environments in brilliant detail.

If you are interested, I wrote about VERTICO for The Conversation.

I’m also the PI of ARCADE, an ALMA Development Study that is developing a state-of-the-art cloud computing platform for processing and analysing ALMA telescope data.

Here is a relatively up-to-date CV.

Science Communication

I’m also a passionate science communicator and outreach enthusiast. When I’m not peering at the Universe I spend my time talking about it through radio, writing and award-winning public talks!

In the most extreme regions of the universe, galaxies are being killed. Their star formation is being shut down and, as an astronomer, I want to know why. The Virgo Environment Traced in Carbon Monoxide survey (VERTICO), is investigating in brilliant detail how galaxies are killed by their environment. Credit: McMaster University
