About

Originally from southern California, I moved to the far north where I obtained my undergraduate degree in Mathematics, followed by an MSc in Mathematics and Statistics from the University of Alaska Fairbanks. After five years as a researcher at the University of Washington, and a year as a stay-at-home Dad in Dublin, I moved to the far south for my PhD (Population modelling of seabirds) at the University of Otago. Following stints at Clark University (Massachusetts) and leading the Statistics group at the University of New England (New South Wales), I returned to Otago in 2017.

Teaching responsibilities

Teaching responsibilities include:

STAT 210 Applied Statistics (Course Coordinator)
STAT 371 Bayesian Data Analysis (Course Coordinator)
STAT 441 Topic in Advanced Statistics (Official Statistics, Local Coordinator)
MARI 401 Advanced Methods in Marine Science

Research Interests

Ecological, Environmental, and Bayesian Statistics. Much of my work brings quantitative methods to the study of marine systems, and trying to understand and address humankind’s impact on them. This includes designing multi-factor experiments for studying ocean global change, developing tools to help manage impact on marine megafauna from fisheries, and developing statistical models for chemical sensors used for environmental monitoring. I maintain a secondary interest in health applications, particularly health outcomes research.
