I am a Stipendiary Lecturer in Pure Mathematics at Exeter College (University of Oxford), teaching A2: Metric Spaces and Complex Analysis in Michaelmas ‘22-23.
I was a tutor and a TA at the University of Oxford, the Hebrew University of Jerusalem and Reichman University (IDC Herzliya). I taught linear algebra, discrete mathematics, general topology, set theory, mathematical logic, infinite groups, geometry of surfaces, group theory and integration.
My research is in geometric group theory and my work explores connections between geometry, topology and profinite rigidity.
I am also interested in model theory and the first-order theory of groups.
