Every measurement is a promise to the people behind the data.
My mission is to carry science the whole distance — from the sample to the standard to the decision — so that no worker, no child, no community carries a chemical burden that evidence could have prevented. Knowledge that stops at publication protects no one. I make it act.
A world where every exposure is measured, understood and acted on.
One generation from now, our chemical environment should be as measurable as the weather — open data, shared standards, decisions made with evidence, empathy and courage. That is the exposome decade. I intend to help build it: as a scientist, as a convener, and as a founder.
One scientist. The whole chain from evidence to impact.
Most experts stop at the paper. This practice runs the full arc — the science, the standards, the policy, the industry application and, when the moment is right, the venture.
Credibility you can verify.
Delivery you can feel.
From the lab bench to the negotiating table.
A PhD in exposure science at Wageningen. Guidance work at EFSA. PFAS epidemiology at Padua. Senior scientific officer at RIVM advising on Europe's landmark PFAS restriction. Exposure science inside global industry. And since 2018, chairing the international working group that sets the direction of human biomonitoring in Europe.
Every step taught the same lesson: evidence only protects people when it reaches a decision. MZJ is that lesson, turned into a practice.
Rigour of a scientist.
Rhythm of an operator.
Half of every problem is asking the question precisely — scientific, regulatory or commercial. We start there, together.
Data, literature, measurement, networks. Conclusions you can defend in front of a regulator, a board or a reviewer.
Findings become instruments: a dossier, a protocol, a strategy, a study, a product. Something a decision-maker can act on.
Training, standards and follow-through, so the capability stays with you after the assignment ends.

See publicationsHave a problem where science meets a decision?
Regulatory, industrial, academic or entrepreneurial — one conversation is enough to see whether this is a fit.
Built on evidence.
Driven by restlessness.
Every chapter of this journey crossed a border — between countries, between disciplines, between science and the decisions it should inform. That crossing became the profession itself.
What I believe
- Evidence only protects people when it reaches a decision
- Standards multiply science; silos bury it
- Data should be FAIR — findable, accessible, interoperable, reusable
- The best science is built with, not just for
Four chapters, one thread.
From a doctorate on chemical risk to Europe's biggest chemical restriction, from a single lab to a global network — the thread is always the same: close the gap between what science knows and what decision-makers do.
Science that stays in a journal protects no one.
From a career to a company.
MZJ is the next chapter: an independent practice — and a growing venture — that puts fifteen years of science, standards and networks at the service of the institutions, companies and founders shaping environmental health. Advisory, research leadership, coordination, and co-built ventures. The same thread, at a larger scale.
The best chapters are written with partners.
If your ambition sits where science meets decisions, we should talk.

What audiences ask for.
Why measuring real-life, whole-life exposure will reshape public health — and who will lead it.
Inside Europe's landmark restriction: what it means for industry, science and society.
From biomarker selection to FAIR data — the standards that make studies comparable and credible.
Where artificial intelligence genuinely helps risk assessment — and where trust must be engineered first.
Need a speaker who has actually done the work?
Every talk draws on live regulatory files, real studies and a global network — not slides about slides.
A network that spans the whole field.
Standards are written by communities. Since 2018 Maryam has chaired the ISES Europe working group on human biomonitoring, convening experts across institutes, regulators and industry worldwide.

Where the work has lived.
PhD in exposure science — risk assessment of chemicals.
European Food Safety Authority — guidance development on chemical exposure risk assessment.
Environmental epidemiology research — PFAS exposure and cardio-metabolic health.
Senior scientific officer at the Dutch National Institute for Public Health and the Environment — advising on the European PFAS restriction.
Exposure science practice inside global industry — where standards meet operations.
Chairing and convening the international human biomonitoring community since 2018.
The network is part of the offer.
Assignments come with access: the right expert, lab, dataset or institution — usually one introduction away.
Notes from the interface.
Short, honest reads on where exposure science, regulation and enterprise are heading — written from inside the files, not above them.
Themes
- The exposome decade
- PFAS & chemical regulation
- FAIR data & AI in risk assessment
- Science as a venture
Three questions worth your time.
Everyone is measuring. Few are measuring comparably. The winners of the next decade will be the ones whose data can talk to everyone else's.
Read the practice RegulationWhat the PFAS restriction really changes — for everyoneBeyond the headlines: how Europe's landmark restriction reshapes product design, supply chains and the evidence companies must hold.
Read the practice AI & trustAI in chemical risk assessment: trust before speedAI will transform risk assessment — but only where transparency, validation and governance are engineered first. Here's the order of operations.
