About me
I am Thanh Le (Lê Viết Lưu Thanh), a Math PhD Candiate at UNL (expected graduation May 2027). Here is my LinkedIn.
Please contact me via email: tle51[at]huskers[dot]unl[dot]edu
I completed my MS in Math at UNL in 2023, and BS in CS and Math at Fairfield University in 2022.

Research
I am co-advised by Dr. Xavier Pérez Giménez and Dr. Vinod Variyam. My current research topics are:
- Probabilistic Combinatorics (with Dr. Pérez Giménez): We have been working on a project about thresholds for Hamitonicity in directed random graphs with some degree conditions.
- Deep Learning (mostly with Dr. Variyam’s team): We study what the theoretical capabilities and limitations of Transformers (a deep learning architecture). Typical papers in this research line include Hahn 2020, Strobl et al. 2024 (a survey).
Recent news
- Fall 2025 and Spring 2026: I am co-organizing UNL’s Discrete Seminar (DisCo).
- June 2025: I am attending SLMath’s summer school “Local Limits of Random Graph” at Paris-Saclay University, France
- May 2025: I gave a talk in the Discrete Seminar (DisCo) of UNL’s Math department. The talk was titled “On the existence of Hamilton cycles with a periodic pattern in a random digraph with degree at least 2.”
- April 2025: I attended Lake Michigan Workshop on Combinatorics and Graph Theory at UIC.

Other Stuff
My hobbies: Soccer, Writing. I maintain a little blog in Vietnamese here (Facebook page).
Micellaneous cool stuff:
- This site was so easy to create, thanks to academicpages. No coding experience required, totally free - I highly recommend.
