What brought me to MUN? What keeps me at MUN?:

After graduating from Memorial in 2006 with an undergraduate degree in electrical engineering, I spent 8 years at the University of Toronto completing graduate studies. As much as I loved Toronto and U of T, I always knew I’d like to return to Memorial University. Besides having family nearby, I knew Memorial to be a great school with excellent faculty and students, and I knew it was the type of environment in which I would be happy building a career. Also, as an undergrad in electrical engineering with a strong interest in health and medicine, I always wished there were opportunities here at Memorial to pursue biomedical engineering. Now, being able to return and be part of a fantastic new initiative between the Faculties of Medicine and Engineering to build educational and research capacity in this area is incredibly exciting.

I am always looking for qualified and motivated undergraduate and graduate students interested in biomedical engineering.  Please contact me directly if you’d like to discuss upcoming opportunities.

Research/Teaching Summary:

My research interests and expertise lie in physiological signal processing and pattern recognition, and specifically in brain-computer interface (BCI) research. I am working to grow a research program in the development of non-invasive passive brain-computer interfaces and mental state monitoring technologies based on electroencephalography (EEG), and my focus right now is on applications to increase safety in high-risk work environments (e.g., cognitive load/stress monitoring during real-time operation, monitoring of expertise development during training).
My teaching activities to date have been largely in the Department of Electrical and Computer Engineering, in analog and digital signal processing.
