I am a PhD candidate in Decision Sciences at INSEAD. I am immensely fortunate to be advised by Hamsa Bastani and Spyros Zoumpoulis.

My research studies how to design and govern human-AI systems that improve decision quality and performance without weakening human learning. Across behavioral and field experiments, industry collaborations, and mathematical modeling, I examine when AI guidance helps people make better decisions and when it backfires by substituting for effort, disrupting cognitive flow, or encouraging over-reliance.

My work highlights a central tension in human-AI collaboration: AI assistance that improves immediate performance can also reduce decision-makers’ situational awareness in subsequent decisions, degrading performance. It has also shown that AI help can undermine long-term learning when it replaces productive struggle within a learner’s Zone of Proximal Development. My goal is to develop evidence-based frameworks that help teams and organizations deploy AI in ways that improve productivity while sustaining human judgment and skill development over time.

Prior to my PhD, I embarked on an entrepreneurial journey, earning recognition on the Forbes 30 Under 30 list for Greece. I also contributed to women’s economic development through my public policy and education roles at MExoxo.

I hold a B.S. and M.S. in Electrical and Computer Engineering from the National Technical University of Athens.
