Joleen Carlberg is currently the Vera Rubin Postdoctoral Fellow at Carnegie's Department of Terrestrial Magnetism. She is interested in the red giant phase of stellar evolution and its consequences on exoplanetary systems. Specifically, she uses optical spectroscopy to study the composition and rotation of red giant stars to look for evidence of the tidal engulfment of planets. Her current work focuses on open cluster red giants, such as M67, using the The Magellan Inamori Kyocera Echelle (MIKE) spectrograph.

Additionally, she works on several projects with the Apache Point Observatory Galactic Evolution Experiment (APOGEE), one of four surveys in the third Sloan Digital Sky Survey (SDSS-III). APOGEE is studying the kinematics and chemistry of the Milky Way with near-infrared spectroscopy, and the data provide opportunities for numerous ancillary science programs. She collaborates on stellar projects to better understand the binary fraction and rotation of both red giant and M dwarf stars.
