About

Juba Ziani is an Assistant Professor in the H. Milton Stewart School of Industrial and Systems Engineering. 

Prior to this, Juba was a Warren Center Postdoctoral Fellow at the University of Pennsylvania, hosted by Sampath Kannan, Michael Kearns, and Aaron Roth. Juba completed his Ph.D. at Caltech in the Computing and Mathematical Sciences department, where he was advised by Katrina Ligett and Adam Wierman.

 

Research

My research lies at the intersection of Computer Science, Operations Research, and Economics. I use tools from learning theory, game theory, and optimization to address technical and societal challenges arising from the rise of AI, ML, and data-driven decision making. I am particularly interested in: 

1. The economics of data, in a world of exchanging data has become crucial to building powerful AI tools;
2. The privacy considerations from using larger and larger amounts of personal and sensitive data, with a focus on Differential Privacy; 
3. The societal considerations around AI, understanding the impact of AI tools on and ensuring that algorithms and automated decision-making tools do not harm society; 
4. The performance of ML models in high-stake environments when strategic user responses and distribution shifts are commonplace.

Teaching

My teaching interests lie at the intersection of game theory, microeconomics, fundamental algorithms in AI and ML, and responsible AI. I teach these foundations both that the undergraduate and graduate level, and integrate theory and practical applications to equip students with analytical tools for decision making in real-life contexts.
