I received my PhD and MSc in Applied Mathematics both from Tehran Polytechnic under supervision of Professor Mehdi Dehghan in 2010 and 2006, respectively. I got my BSc in Applied Mathematics from Shiraz University in 2004.

My research interests include numerical linear and multilinear algebra, and interval arithmetic. I am particularly interested in numerical algorithms for working with matrices, tensors, and tensor decompositions. During 2014-2017 I developed Chebfun3, a software package written in object-oriented MATLAB for numerical computing with 3D functions defined on a box.
