Operations Research Postdoctoral Researcher

About the role

We have an opening for a Postdoctoral Researcher in Operations Research to conduct research in the areas of stochastic, decentralized, and/or multi-level optimization, with specific application to critical infrastructure systems.

Responsibilities

• Develop and extend mathematical programming (e.g., mixed-integer programming, nonlinear programming, and mixed-integer nonlinear programming) formulations of core critical infrastructure operations and planning optimization models.
• Design and implement high-performance (parallel) solvers for stochastic, multi-level, and/or decentralized optimization models of critical infrastructure.
• Analyze and mitigate performance bottlenecks in parallel solver implementations.
• Publish research results in external peer-reviewed scientific journals and participate in conferences and workshops.
• Contribute to grant proposals and collaborate with others in a multidisciplinary team environment to accomplish research goals.
• Pursue independent (but complementary) research interests and interact with a broad spectrum of scientists internal and external to the Laboratory.

Requirements

• Ability to secure and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship.
• Ph.D. in Operations Research, Industrial Engineering, Computer Science, Applied Mathematics, or closely related field.
• Fundamental knowledge of at least one open-source algebraic modeling language (e.g., Pyomo, JuMP) for mathematical optimization.
• Fundamental knowledge of at least one widely used mathematical optimization solver (e.g., HiGHS, Ipopt, Gurobi, CPLEX, and Xpress).
• Fundamental knowledge and experience developing software in a high-level language such as Python, Julia, and C++ (Python preferred).
• Experience developing specialized algorithms for mathematical optimization problems considering either adversarial (multi-level) behaviors, uncertain inputs, or at a large scale.
• Publication record in high-quality peer-reviewed journals and/or conferences.
• Proficient verbal and written communication skills to effectively collaborate in a team environment, present and explain technical information to technical as well as non-technical audiences, document work and write research papers.

Qualifications We Desire

• Experience with high-performance computing systems, specifically parallel programming libraries such as MPI.
• Experience with the application of mathematical optimization to critical infrastructure systems, including electricity grid and natural gas networks.
• Experience processing and analyzing critical infrastructure information.
