About
I build AI-powered developer tools on Posit's stack and ship them at enterprise scale — 35 packages, 84 Shiny apps, and direct collaboration with Posit engineers. At Dow, I lead AI strategy for a 3,000-person R&D organization while navigating the same disruption reshaping how all software gets built. I've been building for what comes next.
Open Source
Bridges Shiny apps and AI agents via the Model Context Protocol. Auto-detects inputs, tracks the reactive graph, and routes tools — so any Shiny app becomes an MCP server.
Agentic AI workflows for R. Multi-agent delegation, tool policies, pre/post hooks, structured output, and streaming with a terminal CLI.
Tidymodels-native package for measurement science — brings psychometric and analytical measurement models into the tidymodels framework with a consistent, composable API.
Size exclusion chromatography tools built on tidymodels. Calibration, molecular weight distribution analysis, and integration with the measure ecosystem.
R port of Stanford NLP's DSPy framework — declarative, self-improving language programs. Prompt optimization, module composition, and cost tracking. Officially listed by Stanford.
Early-mover RStudio IDE addin integrating LLMs into the coding workflow. Multi-provider support, published to CRAN. Paved the way for Posit's native AI tooling.
Also contributed to: ellmer, py-shiny, shinychat, tidyr, dplyr, parsnip, embed, rsample, Stanford DSPy, Axolotl, Mistral.AI

Experience
Research Scientist
Dow · Midland, MI- Lead AI strategy for Dow's 3,000-person R&D organization and directly advise the CTSO on AI and digitalization priorities.
- Contributed to Posit open source projects including ellmer, py-shiny, shinychat, and core tidyverse packages.
- Architected an AI-powered emissions monitoring platform serving 27 manufacturing sites across 6 countries, with an LLM pipeline that auto-converts Excel workbooks into production Python code.
- Co-developed an LLM-powered Patent Analysis tool highlighted to Dow's Board of Directors and Microsoft's leadership team.
- Scaled generative AI from proof-of-concept to enterprise-wide deployment, expanding secure access to frontier and open models across the organization.
- Built and deployed 84 Shiny applications (50 R, 34 Python) to Posit Connect — including ML model APIs, live data pipelines, and 19 AI-powered production apps.
- Authored 35 packages (25 R, 10 Python), establishing package development patterns and CI/CD workflows adopted organization-wide.
- Created shinymcp, deputy, dsprrr, and gptstudio — open source AI developer tools spanning MCP protocol, agentic workflows, prompt optimization, and IDE integration.
- Managed Posit enterprise products (Workbench, Connect, Package Manager) for 400 users: secured funding, defined support model, led roadmap discussions with Posit leadership.
- 3× posit::conf speaker (2023–2025), R/Pharma presenter, and international R user group speaker on LLM integration and AI tooling.
Associate Research Scientist
Dow · Midland, MI- Founded and led the data science strategy team for Analytical Science, defining best practices for R, Python, and AI enablement across a 400-person organization.
- Designed and delivered the Citizen Data Science curriculum and led Posit Academy mentorship, achieving >90% training completion and mentoring 25+ professionals across multiple organizations.
- Key contributor to Dow's enterprise AI Strategy, defining the organizational operating model and leading the Scale & Standards sub-team.
- Led an AI-enabled plastic recycling project, building ML models that maintained product performance with increased recycled content — recognized with two internal awards.
Senior Chemist
Dow · Midland, MI- Pioneered a deep learning approach to modeling product performance in manufacturing, resulting in a patent submission and $2.3MM+ in realized value.
- Built a Shiny-based Duty Drawback tool enabling $2.5MM one-time and $1.2MM annual savings for the supply chain organization.
