Research

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.
