Marshall Ward Lochbaum of Raleigh, North Carolina, is a software developer and programming language implementer. At University of North Carolina at Chapel Hill, he earned a Master of Computer Science degree, was distinguished with the highest honours in mathematics as a Bachelor in Mathematics and Computer Science with a minor in Physics, and received the 2013 Alfred T. Brauer and 2014 Archibald Henderson prizes. Lochbaum is the designer and implementer of the I programming language which generalizes the array and functional capabilities of J to deal with a much broader variety of data structures.
Career
Before joining Dyalog, Lochbaum programmed extensively in J, both as a hobbyist and as a professional at ThomasNet and BEST, llc. He has also contributed to the J interpreter.
Since February 2017, he has worked as a software developer at Dyalog Ltd., mainly on speeding up the implementation of Dyalog APL, but also contributing to language development. He has achieved significant speed-ups across all parts of the language, implemented new primitives, and designed extensions to existing ones. He also is a frequent workshop host and presenter and Dyalog User Meetings and other events.
