### Fall 2018:

GSI for math 228a: Numerical Solutions of Differential Equations,
taught by Lin Lin.

Office hour: Tu 3:45-5:45 at 824 Evans.

My research interest is in numerical analysis.

Currently, I am working on computing sensitivity of long-time averaged objectives in chaotic dynamical systems.

My main contribution to this problem is developing the Non-intrusive Least Squares Shadowing (NILSS) algorithm, defining the adjoint shadowing direction, and developing the Non-Intrusive Least Squares Adjoint Shadowing (NILSAS) algorithm.
