Atlantic Category Theory Group
Halifax, Canada

The Atlantic Category Theory Group is an interdisciplinary research group composed of faculty, postdocs, and graduate students at Dalhousie University, Saint Mary's University, and Mount Allison University.

Research Interests

Our research interests focus on pure and applied category theory, including double categories, bicategories, enriched categories, higher dimensional category theory, adjunctions, categorical lattice theory, complete distributivity, Hopf algebras, homological algebra, operator theory, categorical logic, the mathematical foundations of computer science, the semantics of programming languages, models of quantum computing, computational category theory, constructive mathematics, topos theory, and the categorical theory of database systems. To find out about the interests of individual faculty members, you can follow the links to their home pages.


We welcome applications from prospective graduate students and/or postdoctoral researchers. Please contact the individual faculty members for more information.


The group meets weekly in the Atlantic Category Theory Seminar.
