## Featured Research

**Julianne Chung**- Inverse problems arise in many applications, such as biomedical imaging, astronomy, and geophysics. For example, in image deconvolution, the observed image is degraded by blur and noise, and the goal of the inverse problem is to reconstruct an approximation of the true image. A significant challenge is that the inverse problem is ill-posed, meaning small errors in the data can result in large errors in the solution. By incorporating prior information, regularization is a standard approach to modify the problem and overcome the inherent instability of the problem. Dr. Chung's research is to develop regularization methods and software for computing solutions to inverse problems.

The figure shows an example from image deconvolution. The blur function and observed image are provided, and regularization was used to obtain the reconstructed image.
