Jeff Allen

Postdoctoral Researcher-Computational Sciences


Jeff Allen is a postdoctoral researcher in the Complex Systems Simulation and Optimization Group in the Computational Science Center. Jeff’s professional aspirations are simply to write efficient code and create pretty pictures. He is happiest when there is a complex algorithm to implement or a massive amount of data that needs to be visualized. His work at NREL exemplifies these passions by providing him the opportunity to write a novel Li-ion battery electrochemistry model and develop a wind-farm optimization python package. These sort of real-world applications are a particular favorite as they naturally lead to easy understandable animations.

He received his doctorate in Applied Mathematics at the University of Colorado, Boulder.
