Paul Karchin is well known for his contributions to the development of high spatial resolution silicon charged particle detectors, muon detection systems, and measurement of the fundamental properties of charm particles.

He has led Wayne State research teams working on the HERA-B experiment at the DESY laboratory in Hamburg, Germany, the Collider Detector at Fermilab, muon detector R&D for the International Linear Collider, and most recently, the Compact Muon Solenoid experiment at CERN in Geneva, Switzerland where he contributed to the discovery of the Higgs boson. His current research is focused on the search for quark and gluon substructure and dark matter manifest in anomalous production of electrons and muons in high energy proton-proton collisions.

In addition, he is part of the team upgrading the CMS forward muon detector using micro-pattern gas detectors. Karchin leads a group for the Snowmass 2021 future physics planning workshop studying the prospects for detection of dark photons and exotic Higgs particles using future high energy proton-proton colliders. He is currently a chair of publications for the CMS muon group and serves on the CMS Muon Institution Board and the CMS Collaboration Board. His research has been funded by the Department of Energy, the National Science Foundation, Fermilab and the Universities Research Association. He is an active reviewer for Physical Review Letters and research proposals submitted to the Department of Energy. He recently served on the CERN review panel for the ATLAS muon detector.
