My research interests mainly focus on understanding the role of complex fault geometry in earthquake cycles. During my PhD, I develop a 3D quasi-dynamic earthquake cycle model FASTDASH, which is accelerated using Hierarchical Matrices. With this approach, we can explore nonplanar fundamental geometry complexities such as step over, fault bend and fault roughness. We plan to apply this model to 2023 Turkey–Syria earthquake, and interpret the stress interaction due to fault branches
