Researching interests:
Inverse problems are concerned with determining (usually numerically) causes for desired or observed effects,  which is a type of problems frequently arising in science and engineering. The property that makes inverse problems mathematically challenging is their “ill-posedness”, which renders traditional numerical methods inherently unstable. This means that a solution to an inverse problem might neither exist nor be unique, and even if some generalized concept of solution is introduced, then this solution depends in a discontinuous way on the data.

Theoretical aspects where I have been active include conditional stability and parameter identification in partial differential equations, regularization schemes in non-Hilbert setting, uncertainty qualification in Bayesian approach and filter based methods.
