Overview
Personal Profile
Jeff Allen’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 NLR 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 easily understandable animations.
