Research Interests

My research interests cover many aspects of laser science and related fields. Some of the areas that I have studied most include, ultrafast lasers, optical waveform characterization, fiber optic telecommunications, RF and microwave electronics, and even mechanical engineering (as it impacts optical experiments). Also, I have a great interest in research that seeks to improve characterization techniques for many types of electronic and laser noise (1/f, shot, thermal, amplitude noise, phase noise, and timing jitter).

I am actively involved in the OAWG and O-CDMA projects.
