PhD in Physics with minor in Math, Stanford University, Stanford, CA, 2005
Research Statement:
Our group studies the ways that light, and lasers in particular, can be used for sensing and measurement, communications, and data processing. The research focuses on fabricating, characterizing, and modeling individual lasers, photonic integrated circuits, and photonics-based sensors and instrumentation. We also work on developing new processing techniques and testing novel semiconductor materials and devices. Applications include hydrogen detection for fuel cells, optical spectrum analysis for metrology and next generation fiber optic communication systems, and optical logic and memory for high speed data processing.
Teaching Statement:
In fall semester 2009, I will teach ECE 498LG, "Principles of Experimental Research," which was offered for the first time in Fall 2008.
Research Interests:
- Optoelectronics
- Photonics-based Sensors
- Photonics-based Metrology and Instrumentation
- All-optical Data Processing Systems
- Photonic Integrated Circuits
- Nano and Micro Opto-Electro-Mechanical Systems (NOEMS/MOEMS)
- Semiconductor Lasers, Modulators, and Detectors
- Low Loss Semiconductor/Dielectric Waveguides and Interconnects
- Materials Characterization
- Semiconductor Band Structure Modeling
Undergraduate Research Opportunities:
1. The Photonic Systems Laboratory is accepting applications for undergraduate students interested in completing a senior research thesis in AY 2009-2010. The student must have a solid academic record and be self motivated, eager to test out new measurement or simulation techniques, and able to commit the time and effort during the academic year necessary to complete the thesis (usually >10 hours per week). Programming skills in LabVIEW or Matlab, or prior research experience or coursework in Optics would be a definite plus. Interested applicants should email an updated resume to the address below.
2. The group is also looking for an undergraduate student (at any grade level) to assist on a computer programming project to develop scientific research tools.
