👋🏼 Hey there! I am Stratis, and I am currently pursuing a PhD in computer science, fortunate to be advised by Manuel Gomez-Rodriguez. I have spent fall 2023 as a research intern at Meta AI (FAIR) and spring 2023 as a visitor at Stanford University working with Tobias Gerstenberg. Before starting my PhD, I studied electrical & computer engineering at the National Technical University of Athens, where I completed my diploma thesis supervised by Dimitris Fotakis.
🚨 I am on the 2024-2025 academic job market 🚨
At a high level, I am interested in building AI systems to understand, inform and complement human decisions and judgments in uncertain and high-stakes environments. During my PhD, I have focused primarily on developing machine learning methods for (i) informing decision making in the presence of strategic human behavior and (ii) enhancing the counterfactual analysis of sequential decision-making tasks. In a nutshell, my research interests lie in the intersection of machine learning and:
- causal inference
- game theory
- combinatorial & convex optimization
- algorithmic fairness
- computational cognitive science
