Research Scientist

**Center for Computational and Data-Intensive Science and Engineering**

**My research interest is in the general field of inverse problems. My areas of expertise can be categorized into the PDE-based inverse problems, mathematical modeling, imaging methods, optimization, and high-performance computing. So far, I was focused on applications in two fields: geophysics, and medical imaging. Thus, most of my publications lie at the intersection of applied mathematics, geophysical inverse problems, and medical imaging.**
