Turning Biological Complexity Into Investment Clarity
Bridging Science, Business, and Geography in Agricultural Biologicals
“After 17+ years isolating nitrogen-fixing bacteria, running field trials across three continents, and navigating regulatory submissions in four countries — I built Quadros Bio Advisory because I kept watching good science fail for the wrong reasons.”
— Dr. Patrícia Dörr de Quadros, Founder & CEO
Dr. Patrícia Dörr de Quadros is a Brazilian-Canadian soil microbiologist, entrepreneur, and the founder of Quadros Bio Advisory (QBA) — a science-first risk intelligence company purpose-built for the agricultural biologicals investment ecosystem.
After 17+ years of academic research, field trials, and direct commercial experience at three biological input startups — with real successes and hard-learned failures — she built QBIView™: a proprietary risk intelligence platform that brings scientific rigour to investment due diligence in agricultural biologicals. It tells you exactly what the pitch deck doesn’t.
Patrícia holds a PhD in soil microbiology and has published 38+ peer-reviewed articles with over 2,200 academic citations. She has navigated regulatory approvals across CFIA, EPA/USDA, ECOCERT, and Brazilian SISGEN — and has personally led the formulation, validation, and commercial launch of biological inoculants in North American markets.
Born and trained in Brazil, she brings something no other advisory firm in North America offers: direct, active relationships with Embrapa and Brazil’s federal university research networks — giving clients early visibility into the world’s most advanced biological innovation pipeline before it reaches North American radar.

Why QBA Is Different
🔬 Scientific Depth
PhD-level expertise in soil microbiology, plant-microbe interactions, and biological input development — not borrowed from literature, built from the lab up.
🌾 Commercial Reality
Hands-on experience with what actually works — and fails — in real agricultural settings across Brazil, the US, and Canada.
🌎 Cross-Border Intelligence
Active research relationships with Embrapa and Brazilian federal universities give clients early access to the world’s most advanced biologicals pipeline.
⚖️ Regulatory Knowledge
Practical, direct experience with CFIA, EPA, USDA, and Brazilian MAPA regulatory pathways — not theoretical, not outsourced.
