About
**Théo Piens, PhD in Environmental
Engineering** *Scientific Expert in Life Cycle
Assessment (ISO 14040-44) and numerical
modeling for complex environmental systems* 🔍
**High-integrity technical validation, not
generic consulting** I don’t deliver standard
LCA reports or sustainability communications.
My role is to **scientifically validate**
environmental models and methodologies for
industrial R&D labs, research consortia,
and peer-reviewed publications. I ensure
technical rigor, methodological consistency,
and compliance with international scientific
standards. 🔬 **What I deliver** * **Critical
technical reviews** of LCA studies (ISO
14040-44): system boundaries, allocation
methods, uncertainty analysis, data quality
(Ecoinvent, ILCD) * **Certified numerical
simulations** using ANSYS Fluent and Fusion
360 (e.g. design and thermal modeling of an
induction furnace for space debris processing,
developed in collaboration with NASA) *
**Scientific support for research
publications**: robust methodology sections,
reproducible data workflows (OpenLCA,
Brightway2), peer-review readiness *
**Validation of impact assessment methods**
(TRACI 2.1, ReCiPe, EF 3.0) in real-world
industrial contexts — not theoretical
benchmarks 📊 **Scientific credibility** *
Published **12 technical case studies** on
ResearchGate with full datasets and modeling
scripts available * Regularly engaged by
**COFRAC-accredited laboratories** to verify
carbon accounting methodologies (ISO 14064-3)
* Contributor to methodological reviews for
EU-funded research projects (Horizon Europe)
in circular economy and low-carbon
technologies 🎯 **Why work with me?** * **No
commercial bias**: I do not sell LCA software,
carbon reporting tools, or ESG services *
**Full transparency**: All models and
calculations are documented and reproducible
(Python/Julia scripts shared on request) *
**Peer-level expertise**: I speak the language
of scientists and engineers — no
oversimplification, no greenwashing *
**Operational precision**: My work bridges
advanced research and industrial application,
with a focus on actionable, technically sound
outcomes 🛠️ **Typical deliverables** *
Peer-review-ready LCA methodology
documentation * Verified simulation models
(CFD, 3D process design) * Technical
validation reports for R&D projects *
Expert review of environmental claims
(compliance with ISO 14025, PEF) I collaborate
exclusively with organizations that require
**scientific excellence**, not compliance
checkboxes. If you need robust, defensible
environmental science — not marketing — let’s
connect.
