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


This semester I’m teaching PHY 205 General Physics and PHY 376 Modern Physics Lab. I’m also leading a directed study and reading group on the philosophy of science.


My research is in quantum theory, with a focus on quantum foundations, quantum information, and quantum decoherence. See my list of publications. I also have an interest in biophysics and the philosophy of science.

My research in the news: Nature (2013) | Washington Post | NBC News | BBC News | ScienceNews | Technology Review | Physics Central | PhysicsWorld | Nature (2008)

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.
  • Decoherence and the Quantum-to-Classical Transition (Springer, 2007) is a textbook covering all aspects of decoherence, from technical to philosophical.
