The necrosis of peri-implant tissue is diagnosed as a risk factor in early loosening and subsequent implant failure. To date, there are several efforts to control the necrosis. Moreover, a considerable number of these efforts focus on decreasing the necrosis of surrounding tissue during surgical drilling. In this regard, a lot of studies try to reduce the drilling temperature since tissue thermal necrosis is likely to occur due to drill force and friction.

Inspired by the flagellar motion in bacteria, we followed the simulation of the motion computationally and investigated the effect of flagellum parameters in the swimming of a bacterium or a biomimetic micro-robot to be compared with the predictions of some popular theories such as “resistive force theories”, “slender body theories”, and “regularized Stokeslet method”. We provided a computational model which integrates the fluid and flagella structure and the novelty of this study was the consideration of deformable flagella in the simulations.

Modeling the displacement of thousands of cells that move in a collective way is required for the simulation and theoretical analysis of various biological processes. While studying the social behavior of cells in collective migration, the aim of this research was to model the motion of Madin-Darby Canine Kidney (MDCK) cells in a confluent epithelium. |
Improvement of Implant Geometry Design: Whereas the bone is anisotropic, it is assumed to be an isotropic material in approximately all of the previous computational studies about implants. Another simplification in simulating implant-bone interface biomechanics is the assumption of full or no osseointegration; by contrast, an implant never achieves full contact with the surrounding bone. Whilst not taking into account these two common simplifications, in a computational model, the implant thread profiles were evaluated.

Modeling the Osseointegration: Osseointegration of an implant to its respective peri-implant bone determines the stability and long-term success of the implant. This project evaluated the implant stability in transition to the secondary stability through finite element analyses. Further, it was investigated whether it is needed to have a secondary stability as a full osseointegration for an implant success or not.

Along with the researches in biophysics field (as my primary area of research interest), I have done some researches in prosthodontics, aerodynamics, robotics, and dynamics.

With the increase of short dental implants usage, high crown-implant ratio has become a common finding. The aim of this study was to explore the influence of the ratio over success rate and marginal bone loss of dental implants. It was a collaborated work between the Isfahan University of Technology and the Islamic Azad University, Isfahan branch. I designed and performed the computational simulations and interpreted the data.

As a sophomore, I joined the unmanned underwater vehicles group as an undergraduate research assistant, whereas I was later also appointed as the senior designer of the ensued student team (Pasargad). We studied the autonomous and remotely operated underwater vehicles as well as their aerodynamics, thrust and propulsion systems, autonomously navigation and remote control systems, related electrical circuits, and power systems.
