The Department of Mathematics, Applied Mathematics, and Statistics is delighted to announce that Professor Daniela Calvetti is one of the fifty Simons Fellows in Mathematics for the year 2025. The Simons Foundation, established in 1994 by Jim and Marilyn Simons, advances the frontiers of research in mathematics and the basic sciences through grant funding, support for research and public engagement (https://www.simonsfoundation.org). The purpose of the Simons Fellowship is to provide support for scientists to extend their sabbatical leave to a full year to advance their research. Dr. Calvetti had been supported as a Simons Fellow in 2014, when she spent her sabbatical year working on the mathematics of the brain.

During her sabbatical leave during the 2025-26 academic year Professor Calvetti will work on investigating the theoretical and computational connections between classical Tikhonov regularization and the prior-based Bayesian inversion. The aim of her research is to provide a unified environment for the computational solution of inverse problems that can take advantage of the many advances that have been made on both fronts in recent years, effectively building a bridge between deterministic and probabilistic regularization methods.

Dr. Calvetti is looking forward to her coming year as a Simons Fellow. “I am extremely grateful to the Simons Foundation for this great opportunity. I spent the first half of my career working on the solution of inverse problems from a purely deterministic points of view and the second half reframing the problems in a probabilistic setting. This sabbatical leave will give me a chance to work on the interface between these two approaches.”

In the spring 2026 Professor Calvetti will participate in a semester long program devoted to “Stochastic and Randomized Algorithms in Scientific Computing: Foundations and Applications” at ICERM, the Institute for Computational and Experimental Research in Mathematics, located at Brown University.
