Summary

This proposal is concerned with the mathematical theory of inverse problems. This is a vibrant research field in the intersection of pure and applied mathematics, drawing techniques from several different areas and generating new research questions. Prominent questions include the Calder'on problem related to electrical imaging, the Gel'fand problem related to seismic imaging, and geometric inverse problems such as inversion of the geodesic X-ray transform. Recently, exciting new connections between these different topics have begun to emerge. This project intends to explore the possibility of a unified point of view to several inverse boundary problems and related consequences.
