Education:

PhD: Electrical and Computer Engineering, University of Toronto, Toronto, Canada, 2012

MSc: Electrical and Computer Engineering, University of Calgary, Calgary, Canada, 2007

BSc: Electrical Engineering, Amir-Kabir University of Technology, Tehran, Iran, 2004

Research:

I am a joint member of Digital Systems and Biomedical Engineering Groups, performing research on:

Machine learning

Computer vision

Biomedical signal processing

Biometrics

Our Human Machine Interfaces Lab

Some of My Research Projects:

Brain Signal Classification: In this project, machine learning methods for time series are used for the analysis of human brain states through classification of EEG signals.

Action Recognition: In this project, machine learning methods for time series are used for classification of human actions through 3D location of body joints over time.

Facial Image Alignment: In this project, a very fine alignment of facial images (both 2D images and 3D scans) is sought. This alignment significantly enhances the face classification accuracy afterwards.

Cuff-less Estimation of Blood Pressure: In this project, machine learning methods are used to estimate the blood pressure through vital signals such as PPG.
