Short Bio

Latest News and Activities (older news here)

Research interest

My general field of interest is computational methods for inverse problems arising in medical and geophysical imaging. I recently also started working on data science applications such as training of deep neural networks. My research is interdisciplinary and covers a variety of topics ranging from mathematical theory via the design of numerical algorithms and efficient computational methods towards solving problems arising in real-world applications.

From a mathematical point of view, my work involves variational calculus, numerical solutions of partial differential equations, numerical optimization, sparse linear algebra, multi-level, multiscale and multigrid methods. I am interested in designing efficient implementations using parallel and distributed computing techniques.

Teaching interest

I enjoy teaching regular one-semester courses in applied mathematics, in particular, numerical analysis, numerical linear algebra, numerical optimization, and inverse problems. Further, I like giving graduate level workshops and tutorials related to my research in image registration and PDE parameter estimation.

Academic advising

I have research opportunities for undergraduate and graduate students to work on challenging mathematical problems with applications in medical imaging, geophysical exploration, and data science. Undergraduate students must be currently enrolled at Emory (ideally invited to the Honors program), and Graduate students need first be admitted into Laney Graduate School (more info here). Contact me for more details.
