Professor Knospe’s field of research is ultrarelativistic heavy-ion physics, the intersection of nuclear and particle physics. One of the main goals of research in this field is to learn more about the strong force, which holds nuclei and nucleons (protons and neutrons) together. At Lehigh, Prof. Knospe collaborates closely with Prof. Rosi Reed as part of the Lehigh Relativistic Heavy Ion Group. He works on the ALICE experiment at the Large Hadron Collider (LHC) at CERN, as well as the STAR and sPHENIX experiments at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. He is co-PI on a National Science Foundation Major Research Instrumentation grant to construct an Even Plane Detector for sPHENIX. In 2022 he received a Department of Energy Early Career award to fund work on heavy-quark bound states at RHIC. He also does work related to Diversity, Inclusion, and Equity in physics and STEM.

Research Statement
Biography
Anders Knospe was born in Denver and grew up in Bozeman, Montana. He received his bachelor's degree in physics from Pomona College in 2002 and earned his Ph.D. in physics from Yale University. He was stationed at the CERN particle physics as a postdoctoral scholar, first for the University of Texas at Austin and then for the University of Houston. He joined the faculty at Lehigh University as an Assistant Professor in the Department of Physics in fall 2020. Prof. Knospe has been a member of the STAR, ALICE, and sPHENIX collaborations, where he has used rare, short-lived, and heavy particles to probe the strongly interacting matter produced in high-energy heavy-ion collisions. Within the ALICE Collaboration, he served as leader of the Resonances Physics Analysis Group from 2014-2019, leader of the Light-Flavor Physics Working Group from 2019-2021, and was a founding member of the ALICE Diversity Office. Some of his work is funded by the National Science Foundation and he is a recipient of a 2022 Early Career Award from the U.S. Department of Energy.
Prof. Knospe is co-PI of an NSF-funded project to construct an Event-Plane Detector for the sPHENIX experiment at Brookhaven National Laboratory. Construction of this detector was conducted in his and Prof. Rosi Reed’s laboratories at Lehigh.
Prof. Knospe has signed over 300 publications of the ALICE Collaboration since 2012 and over 70 publications of the STAR Collaboration for 2007-2012, and since 2021. A list of selected publications is below.
