We consider precise composition bounds of the overall privacy loss for exponential mechanisms, one of the fundamental classes of mechanisms in DP.

In many practical applications of differential privacy, practitioners seek to provide the best privacy guarantees subject to a target level of accuracy.

However, these results require that the privacy parameters of all algorithms be fixed before interacting with the data.

We also provide optimal privacy loss bounds that apply when an analyst can select pure DP and bounded range mechanisms in a batch, i. e. non-adaptively.

We design a general framework for answering adaptive statistical queries that focuses on providing explicit confidence intervals along with point estimates.

In large-scale statistical learning, data collection and model fitting are moving increasingly toward peripheral devices---phones, watches, fitness trackers---away from centralized data collection.

We explore the design of private hypothesis tests in the local model, where each data entry is perturbed to ensure the privacy of each participant.

In this paper, we initiate a principled study of how the generalization properties of approximate differential privacy can be used to perform adaptive hypothesis testing, while giving statistically valid $p$-value corrections.

We propose new tests for goodness of fit and independence testing that like the classical versions can be used to determine whether a given model should be rejected or not, and that additionally can ensure differential privacy.

Second, we provide learning-theoretic results that show that such prices are robust to changing the buyers in the market, so long as all buyers are sampled from the same (unknown) distribution.

This models the problem of predicting the behavior of a rational agent whose goals are known, but whose resources are unknown.
