Discrete Optimization
Focus Area • We develop advanced algorithms and modeling tools for a variety of optimization research areas, including engineering design, parameter estimation, inverse modeling, logistics and planning, and design of complex systems. Our research considers a wide range of optimization problems, including integer and linear programming, disjunctive programming, stochastic programming, surrogate-based optimization and...

Drew Philip Kouri
Staff Page • Optimization & Uncertainty Quantification. Biography Drew's research interests include: PDE-constrained optimization, algorithms for solving risk-averse and robust PDE-constrained optimization problems, adaptive sampling and quadrature methods for risk-averse optimization, general frameworks to handle inexactness and model adaptivity in optimization.

Award, June 1, 2015 • Award, DOE. For pioneering theoretical and practical advances in numerical methods for partial differential equations (PDEs), which includes the invention of new algorithms, the rigorous mathematical analysis of algorithms and...

E3SM
Software • E3SM is an Earth System Model being developed by the DOE Energy Exascale Earth System Model (E3SM) project.  E3SM Version 1 was released in 2018.  E3SM Version 2 was released in 2021.  The E3SM atmosphere model runs with the spectral element dynamical core from HOMME, upgraded to include new aerosol and cloud...

E3SM – Energy Exascale Earth System Model
Project • E3SM is an unprecedented collaboration among seven National Laboratories, the National Center for Atmospheric Research, four academic institutions and one private-sector company to develop and apply the most complete leading-edge Earth system model to the most challenging and demanding subseasonal to decadal predictability imperatives. It is the only major national modeling...
