معرفی
John Mackay is an Associate Professor (Reader) in the School of Mathematics at the University of Bristol. His research focuses on geometric analysis, particularly analysis on metric spaces, geometric group theory, hyperbolic groups, and conformal dimension. He is a member of both the Probability, Analysis and Dynamics and Pure Mathematics institutes at Bristol, where he maintains an active research program and teaches undergraduate mathematics courses.
His educational background includes undergraduate studies at the University of Edinburgh, PhD work at the University of Michigan under Bruce Kleiner (2003-2008), followed by a J.L. Doob research assistant professorship at the University of Illinois (2008-2010) and a postdoc at the University of Oxford (2011-2013) working with Cornelia Drutu before joining Bristol.
Mackay's research explores the intersection of geometry, analysis, and group theory, with particular emphasis on conformal dimension, quasiconformal geometry, and the structure of hyperbolic and relatively hyperbolic groups. His work often involves studying metric spaces through their geometric and analytic properties, with connections to harmonic analysis and topology.
His publication record shows consistent output since 2008, with recent work focusing on Poincaré profiles, asymptotic dimension, and the conformal dimension of hyperbolic groups. His most recent publications extend to 2025, indicating active ongoing research. The publications demonstrate a progression from foundational work in conformal dimension toward more complex applications involving random groups, Lie groups, and relatively hyperbolic structures.
Among his significant contributions is the co-authored book "Conformal Dimension: theory and application" published by the AMS in 2010.
Mackay actively contributes to the mathematical community through conference organization, including the "Interactions between Geometry, Dynamics and Group Theory" workshop at Bristol in January 2020, and upcoming events including the "Actions on graphs and metric spaces (OGG Workshop)" at the Isaac Newton Institute for September 2025 and the "Probability, Analysis and Dynamics conference" at Bristol for April 2025.
