The Mathematics and Computer Science Division, MCS, at Argonne National Laboratory seeks candidates for a postdoctoral position in computational mathematics and optimization of digital twins. In this role you will perform research in analysis and implementation of algorithms for solving optimization problems that involve digital twins to model complex systems. Applications include, but are not limited to, data assimilation and control for self-assembly systems, optimal experimental design, and control for autonomous devices. Research will be performed in close collaboration with leading scientists in applied mathematics and computer science. Researchers will have access to cutting-edge extreme-scale computing facilities. Argonne provides a collaborative, open-science environment where scientists from various disciplines and backgrounds are engaged in solving challenging fundamental and practical problems. We actively promote diversity in backgrounds, experiences, and perspectives.
