Susanne Brenner

Susanne Cecelia Brenner is an American mathematician, whose research concerns the finite element method and related techniques for the numerical solution of differential equations. She is a Boyd Professor at Louisiana State University.Previously, she held the Nicholson Professorship of Mathematics and the Michael F. and Roberta Nesbit McDonald Professorship at Louisiana State University, She currently chairs the editorial committee of the journal Mathematics of Computation.In 2019 she was elected President of the Society for Industrial and Applied Mathematics (SIAM).

Brenner did her undergraduate studies in mathematics and German at West Chester State College and received a master's degree in mathematics from SUNY Stony Brook. She obtained her Ph.D. from the University of Michigan in 1988 under the joint supervision of Jeffrey Rauch and L. Ridgway Scott; her thesis was entitled "Multigrid Methods for Nonconforming Finite Elements".

She held faculty positions at Clarkson University and the University of South Carolina before moving to LSU in 2006.
