Technical Due Diligence for Materials | Evidence Review, Claims Risk, Gap Analysis, Validation Plans, 8+ years in R&D

プロフィール概要

I help climate-tech teams, R&D groups, accelerators, and innovation programs make defensible materials decisions without wasting months in uncertainty. My work is decision-led and evidence-based: I review your current technical story, map what is supported vs. weak, identify the specific gaps, and translate that into a practical validation roadmap with stage gates, pass/fail criteria, and a test matrix you can execute with labs, partners, or internal teams. I am a PhD-trained Mechanical Engineer and Materials Scientist with deep experience in sustainable polymers, coatings, and materials performance, including biodegradability, recycled content pathways, durability tradeoffs, and end-of-life claims. Typical outcomes include clearer claims language, reduced technical risk, fewer “unknown unknowns”, and a credible plan that holds up to investor, partner, and regulatory scrutiny. Typical engagements include: • Technical feasibility and diligence (what is viable, what is risky, what must be proven next) • Evidence review and claims risk assessment (what is defensible, what wording creates avoidable exposure) • Testing gap assessment and validation roadmap (prioritized tests, sequencing, and decision logic) • Materials strategy and selection (tradeoffs between biodegradable, recyclable, recycled-content pathways) • R&D strategy support (stage gates, KPIs, partner readiness, pilot planning) • Technical writing for decision-makers (executive memos, review-ready summaries, evidence maps) My working style is structured and fast: clarify your goal, review the available data, then deliver a decision-ready output with assumptions, evidence strength, and recommended next steps. Note: I support editing, review, and technical writing, I do not complete student assignments on a client’s behalf.
