Adam Piggott

Senior Lecturer / First Year Coordinator / Outreach and Engagement Convenor

Adam was an undergraduate at the University of Wollongong (B.Math, Honours first class, and B.CompSci) and a graduate student at the University of Oxford (D.Phil. Mathematics). Working as a mathematician in the USA for 13 years (three years at Tufts University and ten years at Bucknell University), he gained considerable experience teaching undergraduate mathematics within the liberal arts model. He returned to Australia in 2018, spending two and half years at the University of Queensland before moving to the Australian National University in 2021 to become the First-year Coordinator in the Mathematical Sciences Institute.
