Dr. Cheu completed his Ph.D. degree in High Energy Physics at Cornell University. Dr. Cheu is working in the Experimental High Energy Physics group where they search for the most fundamental particles in nature. His current research interests involve searches for dark matter and physics beyond the Standard Model. If they were to discover such phenomenon, it would have a profound impact on understanding the origins of matter, as well as improving our knowledge of the Universe. Dr. Cheu's research takes place primarily at the ATLAS detector, which is one of the experiments at the Large Hadron Collider or LHC. Dr. Cheu serves as the Associate Vice President for University Research Institutes in which he oversees the University-wide centers and institutes. Elliott served as the interim Dean for the College of Science from 2019 to 2021. Dr. Cheu also helped co-chair the 2018 Strategic Planning process for the University of Arizona. From 2008-2019, he was the Associate Dean for the College of Science and in 2017 helped guide the Honors College as interim Dean.
