Courses, lectures, and talks

Instructed courses

  1. ECE 4760 (Digital Systems Design Using Microntrollers): This is a microcontroller laboratory and design course using the PIC32. Started in Spring, 2021.
  2. ECE 5760 (Advanced Microcontroller Design and System on Chip): This is an FPGA laboratory design course using the DE1-SoC. Started in Fall, 2020.
  3. MAE 5160 (Spacecraft Technology and Systems Architecture): A survey in contemporary space technology from satellite subsystem design through launch and mission operations, focusing on the classical subsystems of robotic and human-rated spacecraft, rockets, planetary rovers, and habitats, and with an emphasis on issue of spacecraft-system architecture and design. Taught in Spring, 2020.

Project and writing courses

  1. ECE 6930 (Masters of Engineering Independent Design Projects): The centerpiece of the M.Eng. program is the professional project, in which students apply theory to a real problem, with the guidance from faculty, and often in collaboration with other students. The page below describes projects of my graduated advisees.

  2. ECE 4920 (Technical Writing Seminar): This course fulfills the College of Engineering Technical Communication requirement, and may also be used as an advisor-approved elective. In this class, you will rewrite your final project for ECE 4760 or ECE 5760 for publication in a magazine or journal of your choice.

TA'd courses

  1. Astro 1101 (From new worlds to black holes): Instructors for this course were Steve Squyres and Alex Hayes. Linked below are the supplemental webpages that I prepared for my recitation students each week.

Other talks/posters

  1. Chipsats. An extended discussion of the theory and applications of chip-satellites. (Slides)
  2. The Mandelbrot Set. From an ECE 5760 lecture (above). Linked separately because it is a favorite topic.
