Data Privacy · Data Quality · Machine Learning
I am a research fellow within the Valda team of the Computer Science Department at École Normale Supérieure – PSL, in the framework of the PR[AI]RIE Artificial Intelligence Cluster.

Valda is a joint team between Inria, CNRS and ENS-PSL. More information about Valda can be found here.

I currently develop algorithms for data provenance, uncertainty, and probabilistic inference in SQL systems. Previously, I was a research fellow at CNRS@CREATE in Singapore (Descartes program, WP2: Hybrid AI), where I built voting algorithms for ensemble learning and added differential privacy to machine learning pipelines.

Before that, during my Ph.D. at Télécom Paris, I worked on privacy-preserving ML systems using cryptographic tools and differential privacy. 😎

🔐 Secure Multi-party Computation
Simulate an addition protocol for n parties. All computations are done modulo 220 = 1048576.

Step 1. Choose number of parties (n) and hidden parties (k). You won't have access to the information of the hidden parties

Oh what's that?
