Jeffrey Larson
Computational Mathematician
Argonne National Laboratory
Jeffrey Larson is a computational mathematician in the Mathematics and Computer Science Division at Argonne National Laboratory. He is lead developer for libEnsemble, a Python library to coordinate the concurrent evaluation of dynamic ensembles of calculations. Jeffrey researches algorithms for mathematical optimization that are motivated by real-world applications from areas including particle accelerator design and quantum computing. His current research focuses on the theoretical properties of algorithms for derivative-free optimization and efficiently implementing such methods on world-class high-performance computers. His interests also include scheduling algorithms and vehicle platoon routing. Jeffrey is co-chair of the Argonne ACT-SO High School Research Program, a STEM-enrichment program that partners with the DuPage County NAACP chapter to pair ANL scientists with Chicago-area African-American high school students. He has also taught courses at the graduate and undergraduate levels, including courses at the KTH Royal Institute of Technology in Sweden and the International College of Beijing.
