Kaie Kubjas

Assistant Professor

Aalto University

Since 2017 I am a tenure-track assistant professor in the Department of Mathematics and Systems Analysis at Aalto University. I received my PhD in mathematics in 2013 from Freie Universität Berlin under supervision of Christian Haase and Klaus Altmann. As a postdoctoral researcher I visited Max Planck Institute for Mathematics, Aalto Science Institute, Simons Institute for the Theory of Computing, Institute of Data, Systems and Society at MIT and PolSys Team at Sorbonne University.

I work in the field of applied nonlinear algebra. I am particularly interested in algebraic statistics and applications in biology, for example in phylogenetics and 3D genome reconstruction. I am also interested in questions about matrix and tensor decompositions, e.g. nonnegative and positive semidefinite factorizations, and low-rank matrix/tensor completion. Besides nonlinear algebra, I like to use tools from combinatorics, polyhedral geometry and convex optimization.

In 2022-2023 I was the Vice Chair and in 2020-2021 the Secretary of the SIAM Activity Group on Algebraic Geometry. In 2020-2022, I was the Deputy Convenor of European Women in Mathematics.
