Guy Marshall

Mathematician, Agilist and Systems thinker

ABOUT
Guy is finalising his PhD in Computer Science from University of Manchester, holds an MSc in Theoretical Physics from Kings College London, an MA in Mathematics from University of Cambridge, and is a Chartered Mathematician. He has over 10 years experience in managing people and delivery of software systems, especially data-centric and machine learning systems.

Guy does things he finds interesting, which usually involve data, systems thinking, and people. Where research is beneficial to support decisions, he often uses mixed methods, gathering quantitative and qualitative data to gain unusual insights. A good example of this is his involvement in creating better AI diagrams.

Based in Manchester (UK), he has lived in Poland, India and Iceland, and collaborated with teams located internationally. He is married with two boys, and can often be found in mountainous environments.
