Christina completed her Bachelor of Arts (Honours) in psychology (2009) and Master of Arts in experimental psychology (2011) at Laurentian University, where she focused on binaural beat entrainment, as well as EEG features characterizing states of consciousness. She completed her PhD in Experimental Psychology at the University of Oldenburg in Germany (2015), where she used simultaneous EEG-fMRI methods to discern networks associated with response inhibition with the Stop-Signal Paradigm. Before starting at Archie’s Lab in May 2016, Christina did her post-doctoral research at the Center for Mind/Brain Sciences at the University of Trento in Italy, where she investigated neurophysiological mechanisms contributing to visual attention with the use of multi-modal EEG-fMRI recordings. Christina recorded and analyzed electrophysiological data with a variety of methods to identify brain areas involved in binaural hearing.

Alexander Andrews
Research Engineer

Alex contributed to Archie’s Cochlear Implant (CI) Lab in three main ways:

1. writing software to deliver stimuli and process signals for CI experiments
2. supporting lab members in their stimulus delivery, data processing, and analysis tasks, and
3. designing and building audio-processing circuitry.

Alex’s general research interests are biomedical and rehabilitation engineering, with a focus on cochlear implants, classification techniques and optimization (e.g., prosthesis control), algorithm development (e.g.,heart rate from noisy PPG, EMG onset), and writing easy-to-use software for biosignal processing and analysis (http://www.featurefinder.ca).

Alex completed his M.Sc.Eng. in electrical engineering and B.Sc.(Eng.) in engineering physics at Queen’s University, where he focused on the design and development of an effective finger movement classification system using myoelectric signals. When not at the lab, he enjoys biking around Toronto and being an active member of the city’s music scene.
