### What's new in conductivity imaging

### Abstract

Since the 1980s, significant attention has been given in biomedical imaging towards mapping the electrical conductivity of tissue. The conductivity map must be mathematically reconstructed from some set measurements by solving an inverse problem. Recent work has focused on so-called hybrid methods, which take advantage of the interactions between different types of physical fields. In this talk, I will give a cursory introduction to some of the mathematical models seen in hybrid methods for conductivity imaging as well as their associated inverse problems. If time permits, I will also present the results of some numerical simulations from work I completed on one such modality known as magneto-acousto-electrical tomography.
