Measuring Variable Importance in Heterogeneous Treatment Effects with Confidence
Published in ICML, 2025
PermuCATE is a new method for assessing variable importance in estimating heterogeneous treatment effects. It improves on existing techniques by reducing variance, making it more reliable—especially in low-data settings like biomedical applications.

When Knockoffs fail: diagnosing and fixing non-exchangeability of Knockoffs
Published in Preprint, 2025
This work identifies and addresses failures of the exchangeability assumption in knockoff-based inference by introducing a diagnostic test and proposing a robust alternative construction method.

A principled approach for comparing Variable Importance
Published in Preprint, 2025
The paper introduces an axiomatic framework and a principled approach to create and evaluate variable importance measures (VIMs), ensuring they avoid spurious correlations and enable fair comparisons. It also offers examples to help practitioners choose and estimate suitable VIMs for their goals and data.

Semi-knockoffs: a model-agnostic conditional independence testing method with finite-sample guarantees
Published in Preprint, 2026
We propose a conditional independence testing procedure with valid type-I error and FDR control that accommodates any pretrained model and requires no train–test split.
