Devon Sigler

Researcher III-Applied Mathematics


Devon Sigler was a Researcher-III in Applied Mathematics at NREL. His area of expertise is optimization. Devon has done work in mixed integer optimization, convex optimization, and stochastic optimization. He is currently interested in solving complex energy system problems using decomposition techniques that leverage problem structure to break problems apart so they may be solved in parallel on HPC systems. He is also interested in applying advanced probability theory optimization modeling and algorithms.
