Research Interests

• Mathematical approaches to image processing. Variational functional and PDE based methods for various problems arising in image restorations and segmentation: denoising, deblurring, inpainting, color image, video, shape analysis, texture, multiphase image segmentation and various extensions.


• Identifying Differential equations from single set of given data, regularized k-means and data clustering.


• Numerical methods and scientific computing: New modeling of functionals, mathematical analysis and numerical simulations for applied problems.

CSE PhD and master program
I am the CSE coordinator in School of Mathematics. More information can be found following these links: CSE PhD (Math), CSE MS (Math), CSE Program and CSE Graduate Student Handbook .
I am a faculty in the School of Mathematics. You can apply to Math PhD, not necessarily to CSE-Math PhD, if you are interested in working with myself or any Applied and Computational Math faculty in School of Math. If you are a motivated student with some numerical background who is interested in questions steaming from fundamental mathematical ideas for applications such as mathematical image and/or signal processing, data clustering, idenfitying differenential equations and others, please feel free to contact me. GT Mathematics and Applications Portal (MAP)
GT MAP is a place for research discussion and collaboration. We welcome participation of any researcher interested in discussing his/her project and exchange ideas with Mathematicians. Please go to http://gtmap.gatech.edu/ for more details.
