Congratulations Dennis Zaritsky, Professor of Astronomy, named AAAS Fellow by the American Association for the Advancement of Science

Zaritsky, a professor of astronomy, is being honored for his contributions to the field of astronomy, including research that made connections between dark and luminous matter.

"Astronomical research serves to inspire and awaken curiosity in the broader commnity that we hope translates to other sciences, and even beyond science," Zaritsky said. "I hope that the enthusiasm generated by the University of Arizona's astronomy research program continues to get passed on to the students we teach and the general public."

Zaritsky earned his doctorate in astronomy from UArizona in 1991. He returned to UArizona as a faculty member in 1999.
