Meet the TAs

We are very excited to teach you this fall! Please contact course staff if you have any logistical questions or concerns. Otherwise feel free to email any of the staff members below.

Teaching Assistants (TAs), also known as Graduate/Undergraduate Student Instructors (GSIs), focus their teaching efforts on a particular component of the course, such as sections, exam prep, or walkthrough videos. Head TAs additionally manage a broader component of the course, such as logistics, content, software, office hours, etc.
