I am a PhD student of Bioengineering at Northeastern University.

My research interests are brain computer interface, signal processing, neuroscience and machine learning. I work Under supervision of Professor Dana Brooks and Professor Deniz Erdogmus.

I received my Bachelor of science in Electrical Engineering from Ferdowsi University of Mashhad, IRAN, and my Master of science in Biomedical Engineering from K.N.Toosi University of Technology, Tehran, IRAN.

Here are some of the projects that we are working on at Cognitive systems laboratory:

1- RSVP Keyboard:

A rapid serial visual presentation (RSVP) in conjunction with language models in order to assist letter selection during the brain-typing process with the final goal of developing a system that achieves high accuracy and speed simultaneously. This paper presents initial results from the RSVP Keyboard system that is under development. These initial results on healthy and locked-in subjects show that single-trial or few-trial accurate letter selection may be possible with the RSVP Keyboard paradigm.

2- RSVP iconCHAT

Many individuals with severe communication disorders also have concomitant physical impairments that preclude the use of conventional modes of communication. We have developed an icon-based interface in which concepts are displayed in rapid serial visual presentation (RSVP) within semantic frames to enable individuals to construct messages via a single input key. The input modality may be a keystroke or a brain signal sensed through electrodes placed on the surface of the scalp. The system has direct implications for users with severe speech and mobility impairments and potential application as a language translation/mediation tool on mobile platforms.

3- Meditation EEG data processing

4- Resting State EEG data processing
