Michael Merrifield is an observational astronomer, who uses spectroscopy to study the dynamic of nearby galaxies. With these data, he seeks to understand both the dark matter halos that dictate the orbits within the galaxy, and the detailed orbital arrangements of stars and gas within these systems, in order to understand how they formed.
He also has a long-standing interest in a wide range of outreach activities, appearing regularly on the very successful Sixty Symbols YouTube channel, which he helped establish.
