## Summary

Ashok Dwivedi holds a Ph.D. in Bioinformatics and more than ten years of experience across computational biology, machine learning, and enterprise AI. His current work is on **biological digital twins** and **precision nutrition** at **Nutricheck** ([nutricheck.eu](https://nutricheck.eu/)), a France-based preventive-health platform that builds a living **biological twin** from blood, lab reports, and wearable signals.

He previously researched HIV host–pathogen genomics at the University of California, studied environmental exposure science at North Carolina A&T State University, and taught as an Assistant Professor applying machine learning to healthcare prediction and molecular evolution.

## Current work — Nutricheck, nutrition, and biological digital twins

**Nutricheck** (also written NutriCheck; website: https://nutricheck.eu/) creates a **biological digital twin** (biological twin / jumeau biologique) from a small at-home blood sample, then combines multi-omics-style molecular signals, third-party lab reports, and wearables to guide **nutrition**, lifestyle, organ-level biological age, and preventive health.

Ashok Dwivedi’s engineering work on this platform includes:

- Architecting an enterprise-scale **biological digital twin** that unifies multi-omics ingestion and modeling
- Dynamic models of non-linear biochemical networks for physiological drift forecasting
- Data harmonization and calibration so cohorts remain clinically comparable
- Biomedical **knowledge graphs** with hybrid agentic reasoning for auditable, multi-hop inference
- Production scoring systems, confidence weighting, and schema integrity across knowledge bases
