Andy Badea's Website

I am a third year PhD student at UNC Chapel Hill interested in PDE and Analysis, especially microlocal analysis.

You can email me at akbadea@unc.edu, or find me in my office on the fourth floor of Phillips Hall in room 415.


Teaching

Fall 2025

This semester I am a TA for MATH 233 (Calculus III). I will be teaching recitations and along with other TAs grading your exams. I will not usually be holding office hours, this is something your course instructor does, but you can direct office hours-like questions to me during our weekly recitation.

I have collected in one file all of the problems I assigned in Calc III recitations last year. I am likely to reuse some but not all of these questions this year.

I also plan to upload a collection of optional harder (or sometimes just different) problems for students who are interested. If you have questions about these problems or if you have solved them and would like me to take a look at your solutions then let me know.

If you are interested in the history of this subject, I recommend the nice book A History of Vector Analysis by Michael J. Crowe.

I am also a TA for MATH 653 (Graduate Analysis). Here my role is essentially just to be a grader. If you have questions or issues the easiest thing to do is to find me in person. You can also email.
