Congrats to Sundar -- his paper "To Shuffle or not to Shuffle: Auditing DP-SGD with Shuffling" was just accepted to #NDSS2026!

Only 21 out of 950 straight accepts this round 😳

Joint work with Borja Balle, Jamie Hayes, & @emilianodc.com

To Shuffle or not to Shuffle: Auditing DP-SGD with Shuffling
The Differentially Private Stochastic Gradient Descent (DP-SGD) algorithm allows the training of machine learning (ML) models with formal Differential Privacy (DP) guarantees. Since DP-SGD processes t...

Conditional congrats to Georgi and Sundar - their paper on Discretization in DP Synthetic Data was accepted with shepherding to CCS’25.

Very important work on an overlooked aspect of end-to-end DP pipelines.

Preprint: arxiv.org/abs/2504.06923 -- feedback welcome!
The Importance of Being Discrete: Measuring the Impact of Discretization in End-to-End Differentially Private Synthetic Data
Differentially Private (DP) generative marginal models are often used in the wild to release synthetic tabular datasets in lieu of sensitive data while providing formal privacy guarantees. These model...
