Congratulations to UW Biostatistics graduate student Brian Williamson who received first place in the oral category of the  2017 WNAR (Western North America Region of the International Biometric Society) Student Paper Competition.

Williamson’s winning paper, “Assessing Variable Importance Nonparametrically using Machine Learning Techniques” proposes a new variable importance measure and estimator that can be used in vaccine efficacy trials to gain a better understanding of which factors contribute to whether or not a vaccine works in certain populations.
