Barnes is a Research Scientist at SSI, which he joined in 2011. He works in the area of stellar astrophysics, and has a particular interest in understanding, both theoretically and observationally, the rotation and activity of cool stars. Over the past decade, he has developed a method called "gyrochronology" for deriving the age of a cool main sequence field star from its rotation rate and its color or mass. He devotes significant efforts in studying open clusters whose homogeneous and coeval populations help to disentangle the relevant dependencies.
