General Objectives of CEMI

Consortium for Electromagnetic Modeling and Inversion (CEMI) is a research and educational program in applied geophysical electromagnetics based at the University of Utah. It was founded more than twenty five years ago by Prof. G.W. Hohmann and is headed by Prof. M. S. Zhdanov since 1995. The areas of CEMI research interest have been and continue to be gravity, magnetic, and electromagnetic modeling and inversion methods for accurate and efficient geophysical data analysis in regions with complex structure.
