Associate Professor Alexander Fish is affiliated with the School of Mathematics and Statistics at the University of Sydney, where he works in Ergodic Theory and Additive Combinatorics. His research emphasizes connections between ergodic theory, Ramsey theory, and wireless communication systems. He is supported by Australian Research Council (ARC) Discovery Projects DP210100162 and DP240100472.
- Education: PhD from Hebrew University of Jerusalem (2007), supervised by Hillel Furstenberg.
- Positions: Zassenhaus Assistant Professor at Ohio State University; Van Vleck Assistant Professor at UW-Madison; Lecturer (2012), Senior Lecturer (2016), and Associate Professor (2021) at Sydney.
Research Interests: Fish explores intersections of Ergodic Theory with Additive Combinatorics, focusing on density problems in discrete groups, recurrence, and geometric patterns. His work spans theoretical mathematics and applications in Wireless Communication (e.g., delay-Doppler channel estimation).
Publications: Recent articles highlight advancements in ergodic Zd-actions, approximate lattices, and twisted patterns in density subsets. Topics include Ramsey-type theorems, Plünnecke inequalities, and applications to communication technologies.
