Graduate Teaching Fellow, McGraw Center For Teaching and Learning  Princeton University, 2013 – 2015

As a graduate teaching fellow, I was responsible for leading a university-wide teaching orientation for new assistants in instruction – this 2-day orientation involved discussions of active learning techniques, effective feedback and grading principles, best practices for fostering an inclusive learning environment and dealing with challenges in the classroom. In addition, I also conducted regular workshops on new learning techniques and effective mentoring of undergraduate students. More information about the McGraw center can be found using the link above.

Assistant in Instruction, Electronic Devices and Photonics
Princeton University, Spring 2013 and Spring 2014

ELE 208 is an introductory course on semiconductor devices, taught to sophomores majoring in Electrical Engineering. It starts out with the basics of quantum mechanics, crystals, band structures, and electron transport in the first half of the course. The second half of the class is devoted to detailed qualitative understanding of devices – p-n junctions, metal-semiconductor junctions, metal-oxide-semiconductor transistors (MOSFETs) and bipolar junction transistors (BJTs). We finish the class with a rudimentary understanding of the vastly different kinds of devices like quantum well lasers, high electron mobility transistors (HEMTs), junction field effect transistors (JFETs), complimentary-MOS (CMOS) structures, etc. This part of the course is mainly to understand and appreciate the diversity of semiconductor devices that are used in modern day electronics.

Most of the homework questions for the class require a good understanding of the underlying physics and provides challenging avenues for integrated learning. These questions are copyrighted to me and also Princeton University – if you plan to use any of them for your class, please cite the source appropriately.

In addition, this class also has a 3 hour lab each week, where students fabricate different kinds of devices and perform basic measurements including a bulk heterojunction organic solar cell, crystalline Silicon solar cell, Gallium-Arsenide based HEMT, and Gallium-Arsenide based infrared lasers.

Cleanroom Fabrication Orientation Course
Princeton University, Fall 2011

In the fall of 2011, we developed and executed a 15-day cleanroom fabrication course for incoming electrical engineering graduate students focused on III-V based semiconductor processing. The students fabricated a fabry-perot near-IR GaAs based laser diode, and characterized the electrical and optical characteristics. The laboratory manuals for the laser processing and measurement can be found below.
