## Biography

Nathaniel is an Assistant Professor of Statistics at the University of San Francisco with a PhD from the University of Waterloo. He teaches jointly in the BSDS and MSAN programs at USF. During his academic career he has also worked as a research assistant and consultant with the Business and Industrial Statistics Research Group (BISRG) on various statistical projects resulting in collaborations with several industrial and healthcare organizations.

In general Nathaniel is interested in using data to make decisions, solve problems, and improve processes. Specifically, his research interests lie at the intersection of data science and industrial statistics. He is interested in experimental design and A|B testing, process monitoring and network surveillance, the assessment and comparison of measurement systems, reliability analysis, and variation reduction.

Nathaniel also has experience mentoring undergraduate research and graduate data science internships in the following areas:

- Exploratory data analysis
- Time series analysis
- Machine learning
- A|B testing
- Data visualization
