Kaisa Sofia Matomäki (born April 30, 1985) is a Finnish mathematician specializing in number theory. Since April 2023, she is a full professor in the Department of Mathematics and Statistics, University of Turku, Turku, Finland. Her research includes results on the distribution of multiplicative functions over short intervals of numbers; for instance, she showed that the values of the Möbius function are evenly divided between +1 and 1 over short intervals. These results, in turn, were among the tools used by Terence Tao to prove the Erdős discrepancy problem.
