About ME

I am a mechanical engineer currently enrolled in a Masters of Science program at the University of Alberta. My research focus is on the development of electroencephalography (EEG) technologies for use in the Intensive Care Unit (ICU). This includes designing a one-size-fits-all helmet and corresponding sensors that can be seamlessly integrated into the EEG systems currently used in the ICU at the UofA hospital.

Supervisors:

  • Dr. Christopher Dennison
  • Dr. Albert Vette

 

PROJECT

My research to date is the development of a novel electrode the aims to eliminate the tedious procedures EEG technologists face when administering an EEG to a patient. Once this design is finalized, integrating the sensor into a helmet that can accommodate a wide range of head shapes and sizes will be addressed.  The development of this technology will aid in clinicians being able to reduce the time needed to make medical assessments, and effectively administer appropriate medications to patients in the ICU.

Most of my work takes place in the Biomedical Instrumentation Lab at the University of Alberta. The machine I use to conduct my research is called the Stellate and it is equipped with Harmonie software. This software allows the test administrator to measure the impedances of each applied electrode, and alter the derivatives (electing which electrodes to compare to one another) and montages (how the program sweeps across the head, eg: front to back, left to right).
