The Student Math Center (SMC)
For those of you who don't know, ucla has TAs on call to answer math questions Monday-Thursday 9am-3pm on the third floor of the math building (MS 3974). If you are looking for help with lower division courses you should come and check it out. I do not have a shift for the Spring quarter (2025).
Past Teaching
Fall 2022: Math 33B (Differntial Equations) - Dis 2C and Dis 2D
For some of my classes I have written up discusssion notes, they are often incomplete but contain explainations, examples, and exercises with solutions which may be helpful for other students taking similar courses. The pdfs have hyperlinks for easy navigation. They are labeled with the weeks that they were covered when I taught which hopefully match the pacing when other professors teach.
I hope as a student you are aware of the CAE office which can help with various accessibility issues including temporary issues (like surgeries and broken bones).
TAs and most professors are mandatory reporters, we are here to support you but I understand that sometimes confidential resources are preferred.
If food, finances, housing, mental health, or basic needs are being impacted there are various services on or near campus that can help, I would like to highlight 580 cafe which has resources and connections that can help with a variety of issues,
I said it earlier and I will say it again, the SMC is a great resource if, for any reason, you need help with a math class.
I recently learned about dyslexic friendly fonts - like the one used here called Lexend - if there is any way I can make this page or my teaching more accessible please let me know.
Office hours by appointment are always an option, please feel free to reach out as needed.
Broad Mathematical Interests:
Broadly I am interested in analysis and how it interacts with the fields of geometry, topology, and probability. I am currently reading about Free Probability and Noncommutative Optimal Transport. More specifically I am interested in:
Optimal transport
Sliced Wasserstein metrics - particularly intrinsic and extrinsic geodesics in these spaces since I discovered some of them
Non-commutative optimal transport and other generalizations of calculus of variations to operator algebras
