Welcome to my website. I’m an astronomer interested in understanding galaxies in our Universe.

Please explore the tabs to learn about the work I do with colleagues and students.

I used to tweet regularly about my work and other interesting stories about astronomy/science (Follow me on Twitter). Lately I’m not tweeting, but you can Follow me on Mastodon instead.
