Research
I’m a Research Scientist at the Pacific Biological Station with Fisheries and Oceans Canada. Much of my work involves developing spatial and spatiotemporal statistical models and applying them to problems in fisheries stock assessment, species distribution modelling, and population ecology.
Software
I develop open-source R packages for statistical modelling and reproducible science:
sdmTMB — fast, flexible spatial and spatiotemporal models for species distributions and other ecological data; used by fisheries agencies including NOAA, DFO, and ICES
bayesdfa — Bayesian dynamic factor analysis for finding shared trends across many time series
csasdown — reproducible data-to-document workflows for Canadian Science Advisory Secretariat reports
Reports
I maintain two annual reports on groundfish in British Columbia:
Groundfish data synopsis — a visualization of nearly all available biological and fisheries data for 116 species
Groundfish stock status trends — summarizes trends in stock status and links them to survey-based population indices
Working with me
I can co-supervise graduate students and postdocs through the School of Resource and Environmental Management at Simon Fraser University. I can also host postdocs at DFO, funded by external fellowships or internal DFO funding.
Reach out if you’d like to collaborate on something of shared interest.
I occasionally teach workshops on spatiotemporal modelling with sdmTMB, applied Bayesian modelling with Stan, advanced R, GLMMs, and RTMB/TMB. Get in touch if you’re interested in hosting one.
Outside of work, I enjoy sea kayaking, woodworking, and photography.
