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 no longer tweeting, but you can Follow me on Bluesky (reach out about invite codes). I do also have a Mastodon account.

I love talking and teaching about astronomy in general, so please get in touch using the below form. Although be aware if it’s urgent email will be better. klmasters ‘at’ haverford.edu
