Top SchoolSteve Walker is a Lead Pricing Developer and data scientist with 12 years of experience applying statistical software and mixed-model methodologies across credit risk, insurance, fisheries, and epidemiology. He blends research-grade quantitative skills (PhD in Ecology and Evolutionary Biology) with product and engineering experience from roles in academia, government, and industry, including director-level data science leadership at McMaster and product management at Altair. Steve has a track record of turning ecological and environmental models into production-ready packages and tools used for real-world decision-making, from sport-fish population estimation to insurance pricing. Based in Old Toronto, he is equally comfortable refactoring R packages for distribution and shaping pricing systems at scale, bringing a rare mix of domain breadth and software delivery. An unspoken strength is his ability to translate complex hierarchical statistical models into actionable product features for non-technical stakeholders.
