About me


Welcome to my corner of the internet! I'm currently immersed in the world of academia as a Ph.D. student in the Mathematics Department at Simon Fraser University. Under the guidance of esteemed advisors, Dr. John Stockie and Dr. Ailene MacPherson, I'm passionately delving into research that bridges the realms of epidemiology, eco-evolutionary dynamics, and theoretical biology. My journey in academia began with a thirst for knowledge, leading me to pursue a Master of Science degree at Simon Fraser University, which I completed in 2022. During this time, I collaborated closely with Dr. John Stockie, exploring the intricate dynamics of jellyfish locomotion and feeding behaviors through the lens of numerical simulations. Prior to my M.Sc., I earned my Bachelor of Science degree in Computer Science from the Department of Mathematics and Computer Science Faculty at the AmirKabir University of Technology (Tehran Polyhechnic) in 2019. This formative experience laid the groundwork for my interdisciplinary approach to research, blending mathematical rigor with computational prowess.

Research


As a PhD student, my research interests are focused on the intersection of epidemiology, evolutionary biology, and computational fluid dynamics. In particular, I'm investigating bark beetle infestations, which are a major threat to forest ecosystems worldwide. My work involves examining the dynamics of the host trees using computational fluid dynamics approaches, which allows me to model how the beetles move and interact with the trees. Additionally, I'm creating a new model to depict bark beetle outbreaks and refining the assumptions made in earlier literature studies. By evaluating the severity of various parameters, I hope to gain insights into how to limit the outbreak of these destructive pests. Finally, I'm examining issues related to evolution and local adaptation in the context of bark beetle infestations. My research is multi-disciplinary in nature, with applications to a wide range of fields, and I'm excited to contribute to our understanding of these important ecological issues.
During my Master of Science program, I conducted research on the swimming and feeding dynamics of jellyfish using numerical simulations. Jellyfish are known to possess highly efficient methods of movement, making them a fascinating model organism for biologists. Using the immersed boundary method, I investigated the fluid-structure interaction between a 2D model of a swimming jellyfish and its surrounding fluid, with a focus on jet-like swimming observed in prolate jellies. Through my simulations, I was able to demonstrate that a power-law dependence derived for undulatory swimmers extends naturally to jellyfish using jetting propulsion. I also investigated the feeding technique used by jetting swimmers, which involves exploiting trailing vortices generated by bell contractions to redirect passive prey into their bell interior. Finally, I explored pair-wise interactions between jellyfish, where nearby swimmers generate repulsion forces and turning responses. My research lays the groundwork for future computational simulations of jellyfish swarms, and contributes to our understanding of the fluid dynamics underlying the remarkable performance of these creatures.
