PhD in Physics with minor in Math, Stanford University, Stanford, CA, 2005

Teaching Statement

In spring 2015 and fall 2015, I teach ECE 329, “Fields and Waves I”.
In spring 2016, I will teach, ECE 536, “Integrated Optics and Optoelectronics”.

Research Statement

My research group, the Photonic Systems Laboratory, 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 and photodetectors, photonics-based sensors, instrumentation, and integrated circuits, as well as developing new processing, inspection, and characterization techniques, and testing novel semiconductor materials and devices. Applications include hydrogen detection for fuel cells, carbon dioxide detection for reducing post harvest food loss, optical spectrum analysis and quantitative phase microscopy for metrology, integrated microring Bragg reflectors for narrow linewidth lasers and next generation chip-scale communication systems, and optical logic, memory and switches for high speed data processing.

Undergraduate Research Opportunities

  1. The Photonic Systems Laboratory is accepting applications for undergraduate students interested in completing a senior research thesis in AY 2015-2016. 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 Professor Goddard.
  2. The group is also looking for an undergraduate student (at any grade level) who has taken ECE 444 to develop processing recipes for depositing silicon dioxide using the new LPCVD machine in MNTL. The student would also assist with photolithography, etching, and measuring the optical loss of the resulting devices.
