Expert-led infrastructure for scientific workflows.

in4r is led by Ivo Djidrovski, PhD, combining toxicology and safety-science workflow experience with practical AI infrastructure development.

Portrait of Ivo Djidrovski
Founder

Ivo Djidrovski, PhD

Built by someone who has lived inside the scientific workflow.

in4r is led by Ivo Djidrovski, a scientist and AI systems builder working at the intersection of toxicology, computational workflows, and auditable agent infrastructure. The work is practical: make AI useful where evidence, data privacy, and expert accountability matter.

Scientific foundation

PhD and postdoctoral work across stem-cell biology, toxicology, and next-generation safety assessment.

AI infrastructure builder

Creator/maintainer of public open-source tooling, including O-QT-related workflows and ToxMCP modules.

Published and citable

O-QT publication, ECETOC AI trust work, public VHP4Safety-related outputs, and ToxMCP preprint/suite development.

Community validation

ONTOX and MIT/Roche hackathon wins plus practical work with research consortia and safety-science teams.

Peer-Reviewed Science Behind the Tools

Our infrastructure is backed by published research in computational toxicology. Every tool we build has a scientific foundation you can cite.

ONTOXHackathon WinnersWorkflow Prototyping

Start with one case-study pilot or advisory retainer.

Bring one safety-science or research case study. We will define the pilot boundary, consulting scope, evidence sources, review gates, and deployment path before scaling anything. We are opening pilot and design-partner conversations for teams operationalizing AI in review-heavy scientific workflows.
