From COVID to Commuting – Fred Shone on Population Activity Modeller (PAM)

Listen Later

#11: Fred Shone joins Arfon and Abby to discuss his

journey from engineer to economist to data scientist to PhD student, the development of Population Activity Model (PAM) including the evolution from pandemic modeling to broader population activity insights.

Fred is a PhD student at the UCL Behaviour and Infrastructure Group (BIG). He built PAM when he was technical lead for the City Modelling Lab at Arup.
