In his dissertation, completed while working in the Next Generation Network Systems Laboratory, he studied how to generate and measure the amplitude and phase of broadband optical waveforms in many narrowband spectral slices.
Historically, at Bell Laboratories, he develops devices for space-division multiplexing in multicore and few-mode fibers, builds wavelength cross-connects and filtering devices, and investigates spectral slice coherent receivers for THz bandwidth. He is an avid jazz pianist and enjoys hiking or skiing through the mountains wherever he can find them.
