Professor Charles (Chuck) Keeton studies the mysterious "dark matter" that surrounds galaxies and pervades the universe. Each galaxy's gravity acts as a gravitational lens to distort our view of objects in the background. Professor Keeton observes gravitational lensing with the Hubble Space Telescope and various telescopes on the ground, and analyzes the observations to map the invisible dark matter. He has published a book on the subject, along with a textbook about astrophysics. In 2010 he received the Presidential Early Career Award for Scientists and Engineers from President Obama for his innovative work in the integration of research and education.
