I am in the Civil Engineering department at Qalam University, holding the position of Assistant Professor in Mathematics. I have experience in applying mathematics in mechanics and civil engineering, as well as applying computers to solve differential equations such as Runge-Kutta, Newton-Raphson, and Picard methods, as well as theoretical mathematics and other methods like Euler, etc., for solving differential equations. .I am interested in Topological dynamical systems/ Chaos theory/ Catastrophe Theory and Differential Manifolds Subjects which have been taught to graduate (M. Sc.)students:  Differential Manifolds: https://scholar.google.com/citations?view_op=search_authors&hl=en&m authors=label:differential_manifolds  Topological Dynamics: https://scholar.google.com/citations?view_op=search_authors&hl=en&m authors=label:topological_dynamics  Differential Manifolds  Catastrophe Theory  Chaos Theory  Differential Topology M .Sc. Thesis Title “On The Treatment of instability of phenomenon by methods of Catastrophe Theory” PhD. Dissertation Title "Introduction to Topological Dynamical Systems” Note: Based on this Dissertation I published the following books: 1. “Introduction to Topological Dynamical Systems I” has been published as a book, New York, USA. ISBN: 978-1-940366524. Publisher: Science Publishing Group. "Introduction to Topological Dynamical Systems II" has been published as a book in Germany. With ISBN: 978-3-659-80680-3. 1.
