I’m an Associate Professor in the Department of Physics at the University of Portland, Oregon.


In Spring 2024, I'm teaching PHY 275 General Physics Lab II and PHY 376 Modern Physics Lab.


My research is in quantum theory, with a focus on quantum measurement, quantum optics, and quantum decoherence.

Selected recent publications:

I’m author and editor of two books on quantum theory:

  • Elegance and Enigma: The Quantum Interviews (Springer, 2011) features interviews with physicists and philosophers about the deep questions of quantum theory.
    “A delight.” —D. Rickles, Mathematical Reviews
  • Decoherence and the Quantum-to-Classical Transition (Springer, 2007) is a textbook covering all aspects of decoherence, from technical to philosophical.
    “Excellent.” —E. Merzbacher, Physics Today
    “Thorough and readable.” —A. Zeilinger, Nature
    “Highly recommended.” —N. P. Landsman, Studies
    “A must-have.” —C. Kiefer, Physik-Journal

Other activities

I’m a Series Editor for the Springer series The Frontiers Collection and Quantum Science and Technology; member of the editorial board of the journals Quanta and International Journal of Quantum Foundations; and member of the Foundational Questions Institute.
