About me
I am currently a research fellow at the University of Manitoba, working with Karen Gunderson. Previously, I was a PIMS postdoctoral researcher (2022-2024), also under her supervision. I received my PhD in Mathematics from the University of Regina, under the supervision of Shaun Fallat and Karen Meagher, in 2022. I received my MSc in Numerical Analysis from Shiraz University of Technology in 2015, under the supervision of Behnam Hashemi.
My research interests lie primarily in graph theory, matrix theory, and combinatorics which are tightly connected and complement each other. I am fascinated by the fact that one can understand and solve a graph theory problem by exploring the corresponding matrix problems and vice versa.
Feel free to check out my CV and a brief version of my research statement for more details about my work and experience.
