While studying Cognitive Science, Simon developed a great interest for Machine Learning and Computer Vision. During his one-year stay at the the Volkswagen Research lab in San Francisco, he was working on computer vision in C++. Looking for better alternatives to a cumbersome language like C++ or a slow language like Python got him interested in language design. This quickly led him to pick up Julia, where he supported work by the Julia MIT lab and authored a number of open source libraries for plotting, GPU acceleration and Machine Learning. Today, Simon is a researcher at Nextjournal, where he is responsible for making Julia easily accessible.
