Dr Bradley Rava

Brad Rava is a Lecturer in the discipline of Business Analytics at the University of Sydney's Business School. His research focuses on Empirical Bayes techniques, Fairness in Machine Learning, Statistical Machine Learning, and High Dimensional Statistics.

Prior to joining the University of Sydney, Brad completed his Ph.D. in Statistics at the University of Southern California’s (USC) Marshall School of Business in the Department of Data Sciences and Operations, advised by Dr. Gareth James and Dr. Xin Tong. His graduate studies were supported by the NSF’s Graduate Research Fellowship, USC’s Marshall Fellowship, and USC’s Global Branding Fellowship. Brad also completed his undergraduate degree from USC in Applied Mathematics.

Brad Rava’s research interests focus modern statistical methods for addressing pressing societal problems that arise from combining automated decision making with high-risk scenarios. To properly communicate uncertainty in these high-risk scenarios, Brad’s research has drawn upon Empirical Bayes techniques, Fairness in Machine Learning, Statistical Machine Learning, and High Dimensional Statistics.

The advancement of machine learning in the past decade has had profound impacts on society. Algorithms that were previously expensive and hard to implement have become accessible to the general public. As a consequence, automated decision systems have started being used in sensitive areas such as medical diagnosis, bail sentencing, and financial services. These application areas require a more nuanced view of uncertainty estimation since the consequences of making a mistake can directly impact peoples happiness and quality of life. When artificial intelligence is used to make decisions for many people, it is important that we rigorously control severe consequences and that we properly communicate the uncertainty associated with these mistakes to practitioners.
