> The personal research and advisory platform of Charles Duprat.

Independent research and advisory work on digital systems built to survive reality. Focused on translating technical potential into institutional and social readiness under real-world constraints.

## Areas of work

- **AI strategy**: Governance, use cases, interactive workshops, and pragmatic deployment rules for teams operating without standard tech resources.
- **Software architecture**: Technical framing, architectural audits, and reliability planning for systems that must remain maintainable, accessible, and performant.
- **Digital inclusion and accessibility**: Audits, project framing, training design, and interfaces optimized for users with specific cognitive, visual, or physical needs.
- **Public-sector tools**: Development of mock environments, simulators, and learning interfaces for training and digital mediation.
- **Training**: Hands-on digital training curricula and resources for educators, social workers, and clinical teams.
- **Independent research**: Hard energy lifecycle assessments, policy implications of AI, and the quantified social and physical costs of digital infrastructure.

## Key projects and research

### 1. The Thermodynamic Efficiency Inversion (Working Paper)
A quantitative comparative energy lifecycle assessment (CELCA) demonstrating how generative AI inference sessions on mobile devices consume **4–9x less total energy** than equivalent ad-supported search sessions.
- **Core finding**: Generative AI bypasses the substantial client-side and server-side energy tax imposed by programmatic advertising and massive web page payloads.

- **Constraints**: 
  - The inversion is a mobile (4G/5G) phenomenon; Wi-Fi boundaries narrow the gap to parity for simple tasks.
  - Test-time compute (reasoning models) erodes this efficiency advantage, consuming up to 30x more energy.

### 2. Affinix
A real-time pharmacometric simulator for clinical polypharmacy, demonstrating CYP interactions, genetic profile matching, and PK/PD modeling.

### 3. Le Lab
Simulated risk-free environments and mock administrative interfaces built for digital training, training-the-trainer, and public mediation.
