Stephan Tornier

Dr. Stephan Tornier is a Lecturer at the University of Newcastle, affiliated with the School of Information and Physical Sciences and the College of Engineering, Science and Environment. He specializes in group theory, focusing on the symmetry of infinite discrete structures like graphs and trees, with applications in digital technology. His research integrates theoretical insights with computational methods to advance understanding of mathematical objects.

His research interests include:

• Group theory and generalizations
• Topological and computational group theory
• Totally disconnected, locally compact groups
• Automorphism groups of trees
• Zero-dimensional symmetry

Recent publications highlight his work on prescribed local actions, computational methods, and software development for analyzing mathematical structures. Grants include an ARC Discovery Early Career Researcher Award (DECRA) and SNSF funding. He supervises PhD and Master’s students, emphasizing educational outreach through videos and projects like "What is Symmetry?" for school students.

Awards and Fellowships:

• ARC DECRA (2021)
• SNSF Doc.Mobility Fellowship (2017)
• Swiss Mathematical Society Travel Grant (2017)

His software UGALY, recognized internationally, has been pivotal in non-traditional research outputs. Collaborations with researchers like George Willis and Michael Bywaters underscore his interdisciplinary impact.
