Teaching & Advising

Teaching Experience

• [Fall 2006] Computer Systems: A Programmer's Perspective (15-213)
  • Teaching assistant for sophomore level class
  • Instructors: Prof. Randy Bryant and Prof. David O'Hallaron

  I held weekly recitations and office hours for 30 undergraduate students. I also designed and graded homeworks and exams. During my recitations, I encouraged lively discussions between students, which outlined their difficulties in understanding the material. In one case, these discussions also revealed an error in an exam problem. My in-depth analysis of this error was used as a case study for race conditions in later editions of the course.

• [Spring 2006] Fault-Tolerant Distributed Systems (18-749)
  • Teaching assistant for graduate level class
  • Instructor: Prof. Priya Narasimhan

  I gave a guest lecture on the experimental evaluation of distributed systems. I designed the experimental plan for a class of 30 graduate students. I also guided seven class projects.

• [Fall 2005] Dependable Embedded Systems (18-849)
  • Teaching assistant for Ph.D. level class
  • Instructor: Prof. Philip Koopman

  I selected discussion topics for a graduate-level class with 20 students. I also led the in-class discussions on distributed timekeeping and on synchrony models for distributed systems.

• [Spring 2001] Electromagnétisme
  • Teaching assistant for undergraduate level class at the Ecole Supérieure d’Ingénieurs en Electronique et Electrotechnique (ESIEE), Paris, France.
  • Instructor: Prof. Cristian Florea

  I guided lab work for a section of 20 students. This class was taught in French.
