About

Stephen McCarthy — researcher, builder, writer

I'm a second-year PhD candidate at Maastricht University's Department of Data Analytics and Digitalisation, where I study how large language models shape strategic decision-making through experimental games — with a particular interest in measuring the impact on wellbeing and personal outcomes when AI is involved. Before the PhD, I completed a double master's in Work & Organisational Psychology and Business Intelligence & Smart Services, and an interdisciplinary bachelor's combining psychology, data science, and entrepreneurship — during which I led a 500-member student association and later chaired a national network representing liberal arts colleges with over 5,000 members. Outside of research, I build tools and platforms, make music, write, and am developing a tabletop strategy game called Memnassin.
