Biostatistician | Clinical Trial Designer | Founder of Evidence in the Wild & Zetyra
I build statistical design tools and provide consulting services for clinical trials, specializing in oncology and adaptive designs.
I spent nearly a decade as a biostatistician at Fred Hutchinson Cancer Center and SWOG, specializing in oncology trial design and Phase II adaptive designs.
During that time, I identified recurring failure patterns: protocols locked in before anyone stress-tested the assumptions, interim decisions made on gut instead of simulation, sample sizes calculated once and never revisited. I call these "Zombie Trials"—studies continuing enrollment after mathematical evidence suggested stopping.
I founded Evidence in the Wild and Zetyra on the belief that the most expensive experiment is the one that was doomed from the start.
What drives my work:
- Building Zetyra: the tool I wished I had, combining rigorous validated methods with a modern interface that doesn't require a PhD to operate
- Providing honest consulting through Evidence in the Wild on trial design before teams invest millions
- Democratizing statistical tools traditionally locked behind $5,000-$15,000/year enterprise paywalls
Beyond work, I train for Ironman and marathon competitions. Pacing matters in both athletics and trial design.
Core Philosophy:
- Web-First: Browser-based, shareable designs without installation barriers
- Collaborative: Project-based workflow with scenario comparison and professional reporting
- Transparent: Visible methodology using industry-standard, peer-reviewed packages (gsDesign, SciPy)
Evidence in the Wild provides specialized consulting services for clinical trial statistical design.
Protocol Statistical Review
- Evaluate draft protocols to identify design flaws before expensive development phases
- Review sample size assumptions, endpoint selection, and interim analysis strategies
- Typical turnaround: 1-2 weeks
Sample Size & Power Consultation
- Justified sample sizing for grants, protocols, and regulatory submissions
- Covariate adjustment strategies (CUPED, ANCOVA)
- Adaptive design feasibility assessment
- Simulation-based operating characteristics
Adaptive Design Feasibility
- Honest assessment of whether adaptive designs warrant operational complexity
- Statistical efficiency tradeoff analysis
- Implementation roadmap for complex designs
Interim Analysis & Futility Planning
- Design interim looks and stopping rules before trial launch
- Bayesian predictive power calculations
- Alpha spending frameworks (O'Brien-Fleming, Pocock)
- Futility boundary design
- Early-stage biotech (Series A/B) needing statistical design expertise
- Academic investigators pursuing R01 grants or cooperative group proposals
- CROs requiring independent statistical review
- Medical device companies building biometrics infrastructure
I focus on high-level trial design. I don't provide hourly SAS programming, data cleaning services, or tutoring.

Zetyra is a web-based statistical software platform democratizing efficient clinical trial design.
Phase III oncology trials average $50-100M and take 4-6 years to complete. Conservative design practices inflate costs by ignoring baseline correlations, using fixed-sample designs without interim monitoring, and applying frequentist methods for early-stage decisions. Traditional tools (PASS, nQuery) cost $5,000-$15,000/year per seat with no validation transparency.
Core Methodologies:
• CUPED - 15-35% sample size reduction using baseline-outcome correlations (FDA-endorsed)
• Group Sequential Design - 15-40% expected sample size reduction with interim monitoring (validated against gsDesign R package)
• Bayesian Predictive Power - Quantitative go/no-go decisions using interim data (aligns with FDA draft guidance)
Features: Free tier with all calculators, project management, PDF export, 51 automated tests, transparent validation
