I received my B.Sc. and M.Sc. degrees in Mechanical Engineering from Iran University of Science and Technology, in 2012 and 2014, respectively. I am currently a Ph.D. candidate with the “Neuromuscular Control and Biomechanics Laboratory” at the University of Alberta, under the supervision of Dr. Hossein Rouhani.

During my M.Sc., I worked on technology development for automatic classification of cardiac arrhythmias. Automatic detection and classification of cardiac irregularities is of crucial importance, particularly in coronary care units. For this purpose, I developed a novel Wavelet design approach for optimal feature extraction from ECG signals. Then, using Artificial Neural Networks and Support Vector Machine, my presented method could achieve high classification rate among eight cardiac arrhythmias.
During my Ph.D. studies, I acquired experience on human motion analysis by working on different research projects which directly targeted technology development for motion analysis of the (i) elderly population with limited mobility, (ii) patients with shoulder dysfunction, and (iii) athletes with a high risk of Mild Traumatic Brain Injury. For this purpose, I completed three experimental studies at the Glenrose Rehabilitation Hospital and the University of Alberta campus. As a study coordinator, I overcame the challenges in participant recruitment and data collection during long-term experiments. The main research projects I have been involved are as follows:
- Long-term daily activity analysis through identifying different postures of the body to evaluate using a single chest-mounted Inertial Measurement Unit (IMU).
- Development and clinical implementation of a wearable biomedical device to assess the shoulder motion for the purpose of outcome evaluation.
- Development of a novel concussion active prevention testing device for neck strength evaluation during sub-concussive whiplash test.
Currently, I am working on developing a wearable sensor technology to analyze the lower limb motion in real-time as an alternative to common motion capture system. Successful implementation of the proposed innovative technology will have a revolutionizing effect on therapeutic walking training in several ways. The main advantage of this technology is that it will be affordable and accessible even in small clinics and homes.
Additionally, I have been selected as the Academic Vice-President of Mechanical Engineering Graduate Student Association to liaison with the graduate students and faculty regarding our graduate program concerns. Also, I have been nominated as the councilor of Mechanical Engineering Department in Graduate Students’ Association council of UofA to advocate on behalf of the Mechanical Engineering graduate students. I became involved in such voluntary activities as I always was concerned about improving the quality of our graduate program and providing an efficient connection and mutual understanding between students and faculty.
I commonly use three types of equipment for my research:
- Inertial Measurement Units (IMUs) comprised of 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer to analyze human motion.
- Motion-capture cameras (VICON), mainly to validate the results obtained by IMU systems.
- Pedar Pressure Insole which is a reliable pressure distribution measurement system for monitoring loads between the foot and the shoe.
