Research
My research lies at the intersection of the finite element theory, algebraic topology, discrete differential geometry, computer science, numerical analysis, and scientific computing.
Teaching & Supervision
Topics of Interest
I am currently interested in multi-physics and multi-scale modeling, and finite element methods that utilize CAD models.
Also, I am interested in the applications of AI in physical and computational sciences.
