Dr. Helander is the Chief Technology Officer of OTI ​Lumionics, a spin‐off company he co‐founded with several of his colleagues to commercialize his research.

Dr. Stephen Anthony Pelle

Centre for Medieval Studies

Dr. Pelle completed his doctoral dissertation "Continuity and Renewal in English Homiletic Eschatology, ca. 1150–1200" in September 2012 under the supervision of Prof. Andy Orchard. His dissertation contributes significantly to the understanding of how the Norman Conquest affected broader patterns of literary production in England. This required close command not only of Old and Middle English but of Medieval Latin, excellent paleographical and codicological skills, and familiarity with a wide range of Biblical and Patristic sources in several languages. Dr. Pelle taught Ecclesiastical Latin at St. Joseph's Seminary (for the Archdiocese of New York) and, more recently, at Immaculate Conception Seminary (for the Diocese of Rockville Centre [Long Island]). In September 2013, Dr. Pelle returns to Toronto as a Mellon Postdoctoral Fellow at the Pontifical Institute of Mediaeval Studies.

Dr. Taylor William Schmitz

Department of Psychology​

Dr. Schmitz completed his doctoral dissertation "Attentional Filtering in Young and Older Adulthood" in September 2012 under the supervision of Professor Eve De Rosa. His research in cognitive neuroscience, focusing on the effects of aging on attention, used magnetic resonance imaging (fMRI) to demonstrate that because older adults are seeing more of the world than younger adults, they are less able to filter out irrelevant information.

Dr. Schmitz is a Career Development Postdoctoral Fellow at the Medical Research Council's Cognitive Brain Sciences Unit in Cambridge, UK. He focuses his research on the brain mechanisms that allow humans to selectively encode and retrieve perceptual memories and the impact of aging on these mechanisms.
