Welcome!

Welcome to my website!

I am an assistant professor at the Computer Science Department at Ben Gurion University of the Negev, Beer Sheva, Israel. Before that I completed my post doctoral fellowship at the Department of Earth, Ocean and Atmospheric Sciences in the University of British Columbia, Vancouver (2014-2016). There I worked with Prof. Eldad Haber on geophysical inverse problems.

I obtained my PhD from the Computer Science Department at the Technion (2014), under the supervision of Prof. Irad Yavneh. My dissertation: "Aggregation-based adaptive algebraic multigrid for sparse linear systems."


Research interests:

My broad research field is computational science (or scientific computing). I am interested in developing efficient numerical solution techniques for various large scale mathematical problems, such as parameter estimation and data-fitting inverse problems, non-linear optimization problems, solution of partial differential equations and sparse linear systems. The problems that I consider arise from diverse fields such as machine learning, signal/image processing, and geophysical imaging, for which I develop efficient parallel algorithms and software for solving the problems at hand. Such efficient and scalable algorithms and software are particularly important these days, as the available data get larger in various applications and better algorithms are required for analyzing them.

Current and near-future research projects:

Accelerating and understanding deep learning: That includes efficient parametrizations of CNNs, understanding stability issues in DL, efficient prunning and sparsity-based techniques, optimization techniques for CNNs.

Seismic imaging: robust and efficient solution to seismic full waveform inversion.

Efficient methods for elastic and acoustic wave modelling in frequency domain.

3D shape reconstruction using parametric level set methods.
