RESEARCH EXPERIENCE

 

From Sep'2002, I am enrolled as a M.A.Sc. student (Thesis Option) in ECE department, Concordia University, under the guidance of Dr M. N. S. Swamy (Research Professor, Concordia University) and Dr Rajeev Agarwal (Research Director, Stellate Systems, Canada)

There are many reasons to record EEG. The basic needs being to have a record for later review by neurologist for diagnosis purpose or provide warning before irreversible damage has occurred to brain or with advancements in telemedicine to transmit data form patient to monitoring unit in hospital. Depending on the complexities involved in diagnosis the recording time may vary from few hours to few days . This results in the large chunk of data for neurologist to review. The efficiency in diagnosis depends on neurologist expertise. To help the neurologist with this chunk of data, different automated compression techniques are being investigated. One of techniques follow a stepwise procedure - first the data is segmented (each segment is quasi stationary), then the features for each segment are calculated ,in next stage the segments with similar features are clustered together and as a last stage a GUI is used to show the birds eye view of the complete recording to the neurologist .

The complete success of the technique depends on two main blocks - the segmentation of EEG and the features to characterize the segments. The later is the research topic for my masters.........I have proposed the features based on power spectral density as the descriptors of  background EEG in the compression framework. The work has been accepted as "Compression of long-term EEG using power spectral density" 26th Annual International Conference IEEE EMBS San Francisco, USA, Sep'2004.

From July 2001 to July 2002, I worked as a Project Associate in Indian Institute of Technology, Delhi. I worked with Dr. Sneh Anand (Centre of Biomedical Engineering , IITD) and Dr. Jayashree Santhosh (Computer Service Centre, IITD). There I was working  on design and development of "EEG based communication devices for Spastic people". The project involved finding the EEG changes in motor cortex ,which occur when  a movement is planned and explore how these changes can be used to control devices. Ministry of Information Technology, Government of India, sponsors the project.

During the period I also helped my colleague working on design and development of hardware and software to meet specialized needs of a 16 year old spastic boy , undergoing a treatment at Apollo Hospitals , New Delhi.

I got a useful insight of Intel 8051 micro controller and emulators when I was doing assembly coding for an offline storage device that was supposed to be used for collection and storage of EEG and ECG data.
