Ana-Andreea Stoica

I'm a Ph.D. student in Computer Science at Columbia University, working with Prof. Augustin Chaintreau on social networks and algorithmic fairness.

Since Fall 2019 I am co-organizing the Mechanism Design for Social Good initiative with Rediet Abebe, Irene Lo, Wanyi Li and Francisco Marmolejo Cossío.

I am co-chairing the ACM inaugural conference on Equity and Access in Algorithms, Mechanisms, and Optimization (EAAMO'21), together with Rediet Abebe and Irene Lo, taking place online Oct 5-9, 2021.

About me

My work focuses on mathematical models, data analysis, and policy implications for algorithm design in social networks. I am particularly interested in studying the network structure effects on algorithmic bias through a graph theoretical lens.

I'm Romanian and graduated from Princeton in 2016 with a bachelor's degree in Mathematics and certificates in Computing and Applied Mathematics. Outside of academia I love skiing and modern art. See my CV or contact me for more info!
