He earned his Master of Architecture from the University of Pennsylvania, receiving the AIA Henry Adams 1st Prize Medal and the Spayd Brook Gold Medal as the top-ranking graduate in both design and theory. Brett has exhibited his work at international venues, including the Venice Biennale in 2016 and 2018, as well as the Seoul Architecture Biennale in 2017 and 2019. He continues to actively engage in both architectural practice and discourse. He has practiced architecture across the globe - UN Studio in the Netherlands, Coop Himmelb(l)au in Austria, Perkins Eastman and ARO in New York, CoA in California, IK Studio in Philadelphia and Boston, and many other offices in Asia and North America.

His academic journey includes an Hon. BA in Art History and Studio Art with distinction from the University of Toronto.

Brett occupies an intriguing position at the intersection of art and architecture, which informs his creative approaches to teaching and practicing both disciplines.
