01
Field Trial Design
and Validation
Field trial design that tests biologicals in the system where they actually have to work
Biological product performance depends on three interacting systems: the plant, its microbial community, and the soil-climate environment around them. Quadros Bio designs and reviews field trial programs across agroecological zones, microbial compatibility, application timing, and environmental variability, to predict both commercial and regulatory performance, not just statistical significance in a single plot. Every trial design is delivered and signed by a named PhD.

Scientific and
Regulatory Writing
Registration-grade scientific writing, prepared and signed by a named PhD
Registration dossiers, literature reviews and data-waiver arguments, technical narratives for grants such as IRAP and SR&ED, and white papers for agricultural biologicals. Prepared and signed by a named PhD, built to withstand regulatory and investor scrutiny, not generic drafting.

Scientific Advisory
Consultation
Direct access to a named scientist for a focused technical or regulatory question
A paid working session with Dr. Patrícia Dörr de Quadros for biologicals teams, investors, and partners who need an independent read on a specific scientific or regulatory question. You leave with a clear, accountable opinion you can act on, not a generic summary.

Bio Investment
Intelligence
An independent, named diligence opinion you can place in your investment file
QBIView™ (Quadros Bio Investment View) is not a self-serve report. It is an independent technical diligence opinion, delivered and stood behind by a qualified scientist, across seven analytical dimensions: biological validity, field translation probability, regulatory pathway, and team scientific depth. Most biological claims fail rigorous scrutiny, and many that pass initial evaluation still fall short in the field, after the money is spent. The value is the judgment that separates real from fake, and a name accountable for the call.

Quadros Bio
Brazilian Network
Bridging Brazilian innovation with North American opportunity
Brazil leads the world in commercial agricultural biologicals, backed by a robust public-sector research and field trial infrastructure that most North American investors are unaware of. Quadros Bio Inc.'s expert network maintains active research relationships across Brazil's federal university system and Embrapa, giving us early visibility into promising technologies, emerging talent, and business opportunities before they reach the North American radar.

Why Investors and Strategic Partners Choose Quadros Bio Inc.
Rooted in World-Class Research Institutions
Dr. Patrícia Dörr de Quadros brings two decades of soil microbiology research, with a sandwich doctorate split between UFRGS (Brazil) and the University of Florida, and postdoctoral work at UFRGS, the University of Toronto, and the University of Waterloo. Her academic lineage runs through Embrapa, CBMAI at UNICAMP, UFRGS, and UFSC, with seventeen-plus years of research experience, 38-plus peer-reviewed publications, and direct commercial experience across three prior biologicals ventures. This depth is the backbone of every assessment Quadros Bio delivers.
Network of Experts
A curated network of specialists in soil microbiology, regulatory affairs, agricultural IP, fermentation science, and field agronomy, assembled per engagement, not kept on retainer. The right expertise for your specific question, every time.
Pattern Recognition
We know where biological technologies fail, not from models or literature alone, but from years of direct involvement in product development and commercialization across multiple continents. That accumulated experience allows Quadros Bio to ask the questions that matter most, and to recognize a miscalculated pathway before it becomes a financial event.
Cross-Border Intelligence
Brazil produces more registered biological products than any other market, backed by deeper public-sector research and field trial infrastructure. Most North American investors encounter these innovations only after valuations have climbed. Quadros Bio gets you there first.
