### Spring 2018:

- GSI for Math 128a: Linear Algebra and Differential Equations.

Discussion session: T 11-2 in B3A Evans.

Office hour: M 3-5 at 939 Evans; W 3-4 at 854 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.
