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.

Currently I am the Deputy Convenor of European Women in Mathematics and the Secretary of the SIAM Activity Group on Algebraic Geometry.

Academy of Finland is funding my research through project funding for early-career researchers.

EWM open letter on COVID-19

European Women in Mathematics published an open letter on the impact of the COVID-19 pandemic. The letter focuses on the impact of the crisis on untenured mathematicians, women and parents. Linked to the letter is also a Resources & Discussion Page.
