Gunnar Martinsson has been a member of the Oden Institute and a professor of mathematics at UT-Austin since 2018. Prior to joining UT, he served as a professor of mathematics at the University of Oxford. He was on the faculty at the University of Colorado, Boulder between 2005 and 2017, and prior to that he was a Gibbs assistant professor at Yale University. He completed his Ph.D. at UT-Austin in Computational and Applied Mathematics (CAM) in 2002. CAM was the Ph.D. program that preceded the current Ph.D. program administered by the Oden Institute, the Computational Sciences, Engineering, and Mathematics (CSEM) program.

He was awarded the Germund Dahlquist Prize by SIAM in 2017. He is an affiliated professor of mathematics at the Royal Institute of Technology (KTH) in Stockholm, where he also chairs the scientific advisory board of the MathDataLab.

Dr. Martinsson's research interests concern numerical analysis, scientific computing, and computational data science. His recent work has involved randomized methods in linear algebra; fast solvers for elliptic PDEs, with a particular emphasis on accelerated direct solvers; structured matrix computations; numerical methods for scattering problems, computational fluid dynamics, and acoustics; applied harmonic analysis; fast multipole methods; boundary integral equation methods; modeling of heterogeneous materials; bandgap phenomena; and lattice equations.
