'''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|I programming language]] which generalizes the array and functional capabilities of [[J]] to deal with a much broader variety of data structures. | '''Marshall Ward Lochbaum''' of Raleigh, North Carolina, is a software developer and programming language implementer.

From February 2017 until June 2020, he 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 was a frequent workshop host and presenter at [[Dyalog User Meeting]]s and other events. | From February 2017 until June 2020, he worked as a software developer at [[Dyalog Ltd.]], mainly on speeding up the implementation of [[Dyalog APL]], but also contributing to language development.
