I am a second-year PhD student at University of Toronto. At the moment, I am undergoing an advisorless transitional period. Before that, I was advised by Professor Adrian Nachman. I also frequently commmunicated with Professor Vardan Papyan. The focus of my PhD studies thus far has been about problems concerning adversarial robustness and generalization capability of deep learning models, especially their trade-offs with data/model privacy. Among other things, I study neural networks using tools from spectral theory and a subset of probability theory inspired by statistical physics. Before starting my PhD program, I completed a MSc in pure mathematics, and I had spent some time in the game development industry(ARPG).

I will not be an instructor any time soon.

Currently, I am a teaching assistant for the course MAT137: Calculus with Proofs.
In the summer of 2022, I was a teaching assistant for the course MAT136:Calculus II.
During 2021 fall to 2022 winter, I was a teaching assistant for the course MAT137: Calculus with Proofs.
In the summer of 2021, I was a teaching assistant for the summer course MAT223 Linear Algebra.
From 2017 to 2021, I was a teaching assistant for the year-course MAT 235 Multivariable Calculus.

I was a mentor for the 2022 University of Toronto Math Mentorship Program. I supervised a project on Elliptic Curve Cryptography.
During the 2020-2021 school year, I was a mentor for the Association for Women in Mathematics High School Mentorship Network.

During the 2021-2022 school year, I was a member of the Social Comittee of the Math Graduate Students Association(MGSA) at the University of Toronto.

Actually, I get most of the news from these sites.

Still learning? Still rambling?

A website to draw commutative diagram based on tikzcd. It does the job if you just want some quick diagrams. Be wanred that the previews do not always agree with the outputs produced by some Tex Editors(such as TexMaker).

Are you actually as productive as you think you are? Are you working effectively and efficiently? What is your APM? Here is an app to track the hours spent on various tasks(accurate to documents). There is also an extension for Chromium browsers that does the same thing. It has a little timer that helps you track the total time(in a day) spent on the current website in real time. On Android phones and tablets, there is YourHour. For the real world, I recommend this kitchen timer

Some illustrations I prepared back when I was an undergraduate TA. I was hoping to eventually manga-fy the mathematical trivia I accumulated over the years.

Mountain of Faith(My Blog.) It is currently unpublished because I do not anticipate I will have enough regular updates that are worthy of the cost of keeping a domain. Please see my GitHub repositories for updates.
