Christopher Homes is an experimental condensed matter physicist in the Electron Spectroscopy Group in the Condensed Matter Physics and Materials Science Department at Brookhaven National Laboratory and member of Comscope since 2015. His research focuses on the optical properties of solids. He began his career looking at synthetic metals (organic conductors and superconductors), transitioning to the high-temperature superconductors, and from there expanded the scope of his research to entail studies of strongly correlated electron systems.

Christopher Homes is working on the experimental validation of Comsuite by measuring the temperature dependence of the complex optical properties of strongly correlated materials, specifically the real part of the optical conductivity, for comparison with ab initio calculations. These measurements are performed over a wide frequency range (THz through the ultraviolet) and can also yield polarization information. He enjoys close collaboration with theorists, explaining various anomalous behavior that is (often unexpectedly) revealed by his experiments.

During his physics career path he was strongly inspired by his first postdoctoral supervisor, Prof. Tom Timusk, who had the confidence in him to let him develop the instrumentation that he (and many others) now use to measure the absolute reflectance of materials.
