Angxiu Ni (倪昂修, pronounces as "ang sh-you knee")
I am a PhD candidate at the mathematics department, UC Berkeley.
I will be a BICMR postdoc starting from fall 2021.

On Tuesday, March 2, at SIAM CSE 2021,
I am organizing two sessions on "Linear Response / Differentiation / Backpropagation in Chaos".
Speakers include inventors/contributors of several major algorithms;
there will also be a review on linear response theory.
I differentiate chaos numerically. My main works are:
1. Non-intrusive shadowing algorithms,
the fastest for approximately differentiating chaos.
2. Fast linear response algorithm, the first affordable algorithm for accurately differentiating chaos.
See a video recording of a talk summarizing a big part of my work.
Teaching, Spring 2021
GSI for math 228B: Numerical solutions of differential equations,
taught by Jon Wilkening.
Office hour: W 9-11am PT, zoom number on appointment page. I will mostly stay logged-in during the OH but would be good to give me a heads-up.
My advisers are
and Haixin Chen.
