Description of Research

My current research is in quantum optics experiments involving single photons and entangled pairs of photons.  I have worked with students on a wide variety of projects, including light scattering from microscopic particles, optical tweezers, and negative refraction.  I have also published frequently in physics education journals.

 A map of all of my runs since the start of 2019 can be viewed at City Strides. I ran every public street of Redlands during 2020, except Hwy 38 and a short, dangerous section of Fern Ave. I had run those before. The few streets listed as incomplete are either private or don't exist.
