Video Profile


Dr. Dressel primarily researches quantum information science, quantum computation, and the foundations of quantum physics. These fields are natural intersection points between physics, mathematics, and computer science. 

Modern experimental techniques have enabled the unprecedented control of quantum systems, which has fueled Dr. Dressel's interest in helping to develop active quantum technology as part of the "Second Quantum Revolution." This new technology has catalyzed the rapidly growing fields of quantum computation and quantum simulation and has enabled precision experimental tests of foundational physics. His recent research involves superconducting circuit quantum electrodynamics, weak and continuous quantum measurements, machine learning for physics, and geometric (Clifford) algebraic methods in relativistic physics. Though the bulk of his work is theoretical in nature, he enjoys frequent and close collaborations with experimental teams at a variety of institutions.

Research Group

Dr. Dressel heads the Spin Group at Chapman University, which consists of undergraduate students, graduate students, and postdoctoral scholars. This group is part of the Institute for Quantum Studies, which has prestigious research affiliates around the world who visit Chapman University regularly. Dr. Dressel enjoys collaborating with both experimental and theoretical colleagues from a variety of disciplines, and usually has a variety of ongoing projects and funding sources.
