I was born in Salkuyeh (a very nice village in Langarud, Guilan province, Iran) in 1970. I graduated from Ghoddosi high school of Langarud in 1989. I received my B.Sc degree in applied mathematics in 1994 from Sharif university of technology, Tehran, Iran and M.Sc degree in applied mathematics in 1997 from Ferdowsi university of Mashhad, Iran. I wrote my dissertation under supervision of Prof. Asghar Kerayechian. I received my Ph.D degree under supervision of professor Faezeh Toutounian at Ferdowsi University of Mashhad in May 4, 2003. Then, I joined Mohaghegh Ardabili University of Ardabil, Iran. From February 2012, I have joined the Faculty of Mathematical Sciences, University of Guilan. My research interests are mainly iterative methods and preconditioning for solving large sparse linear system of equations, finite element and finite difference methods and error analysis.
