I am Omid, a Ph.D. candidate at RMIT University. Before I started my undergraduate degree, I worked in industry as a product & industrial designer. While I was completing my Bachelors in Mechanical Engineering, I worked in this field for a biomedical and dental equipment company.
My industrial experience and personal motivations towards engineering design led me to work for Tehran University of Medical Sciences as a mechanical design engineer in an exciting project and teamwork environment that eventually directed me to the wonderful research community.
In 2013 I started my Master’s degree at RMIT University in Mechanical and Manufacturing Engineering. In 2017, I was introduced to obstructive sleep apnea and its consequences for humanity. I was very excited to contribute to this area of science so, I started my PhD at RMIT on numerical modeling of the human respiratory system. We implement numerical modeling methods and techniques to understand the airflow behaviour in various sleeping positions and conditions. This aims to provide a technique that can help specialists provide better treatment solutions to their patients.

Topic: Study of Airflow Phenomena and their effect on the respiratory system
Obstructive sleep apnea (OSA) is a common disease and is considered a serious problem. Lack of proper treatment causes severe damage to oral health. Heart attack, diabetes, blood pressure and daytime sleepiness are common symptoms. OSA is defined by an apnea-hypopnea index (AHI), which indicates its level of severity. Rapid eye movement sleep (REMS) and polysomnography devices are the most common techniques implemented to define the level of obstruction of the upper airway. Treatment suggestions are based on the AHI measurement. However, uncertainty in the measurements can lead to the wrong treatment recommendation. Computational fluid dynamics (CFD) is now implemented as a novel solution to predict the level of obstruction in the upper airway with a high level of accuracy. This project considers applying a combination of the CFD and FEA (finite element analysis) to obtain information that can predict the exact level of obstruction in the human upper airway, which can then assist clinicians to suggest superior treatment solutions.
