 Our research interest is the development of mathematical theories and measurement methods for inverse problems which invert the law of causality to identify the cause of a phenomenon from its results. These problems are ubiquitous in engineering - non-invasive measurements in biomedical engineering, non-destructive inspection of structures and materials, searching for victims buried in rubble after earthquake, indoor navigation for cyber-physical systems - all of these can be treated as inverse problems.
 Our laboratory aims to derive mathematically rigorous and computationally efficient algorithms as well as develop novel sensors for inverse problems.
