About

Thermal radiation is the most abundant form of light and among the least controlled. I design the devices that put it under electrical command, build the instruments sensitive enough to see what those devices do, and integrate both into intelligent thermal-infrared systems.

My group works across the full chain: electromagnetic modeling, nanofabrication, infrared measurement, and the algorithms that read the data out.

I am recruiting PhD students and postdoctoral researchers with a background in nanophotonics, cleanroom nanofabrication, optical or infrared instrumentation, or machine learning. Please email me with a CV and a short note on what you want to build.
