Research Interests

​Stefano Zampini earned his Ph.D. in Computational Mathematics from the University of Milan in 2010. His work mainly focuses on non-overlapping domain decomposition preconditioners of the dual-primal type (namely, BDDC and FETI-DP type methods) for solving large and sparse linear systems arising from finite elements discretizations and IsoGeometric Analysis.

In the past, he worked for the italian Supercomputing center CINECA, with a specific interest in optimization and parallelization of oil and gas applications, and for the italian weather forecast agency.


In recent years, he focused its work on highly heterogenous linear systems, including those of saddle point type arising from Darcy' equations and on electro-magnetics inversion problems.

He is currently an active developer of the award winner PETSc library [1], developed at the Mathematics and Computer Science Division of the Argonne National Laboratory.
