Olof Sisask

Picture of me

I am a Senior Lecturer in the Department of Mathematics at Stockholm University. Education-wise, I am interested in the systematic development of education and in making concepts tangible. Research-wise, my main interests lie in probability, combinatorics, harmonic analysis and number theory. Before coming to Stockholm University, I've been at

Public engagement
Have fun and understand stuff with interactive tools! The text is in Swedish, but the ideas universal. Unfortunately these are not yet fully self-contained, but they will hopefully make sense to you if you attended one of my public lectures at the Stockholm Mathematics Circle 2019, at Alba Nova on pi-day 2018, at Senioruniversitetet in Dec 2018 or the teacher development day Kleinerdagen at the Royal Swedish Academy of Sciences (KVA) in Oct 2017. If you want any of the other materials we used, please email me!

Want to study the emergence of a giant puddle in the random raindrop model? Here's a visualisation. (Puddles merge according to their barycentres.)


I have lectured or otherwise taught many of the fundamental courses at undergraduate level, including Discrete Mathematics, Calculus, Multivariable Calculus, Linear Algebra, Base Math, Euclidean Geometry and Ordinary Differential Equations. I have lectured graduate or advanced level courses in Additive Combinatorics, Extremal Combinatorics and Fourier Analysis.
