Asst. Computational Mathematician, MCS
Argonne National Laboratory
Stefan Wild obtained his Ph.D. in operations research at Cornell University. He joined LANS as an Argonne Director's Postdoctoral Fellow in September 2008. His primary research focus is on algorithms and software for simulation-based optimization problems where derivatives of the objective are unavailable. Currently, he is developing model-based methods for derivative-free optimization that exploit additional structures often found in practical applications, including constraints, discrete variables, computational noise, parallel computing environments, and parameter estimation. In addition to numerical optimization, he is interested in machine learning and numerical linear algebra.
