Dr. Yocheved Yorkovsky

Science Editor — Health, Chemistry & Environment

I earned my PhD in chemistry at the Technion – Israel Institute of Technology, specializing in biochemistry, and I've spent more than four decades as a researcher and lecturer in chemistry and environmental science. My early work was in inorganic biochemistry — metalloenzymes and superoxide dismutase, the chemistry of how living systems defend themselves against oxidative stress — published in journals including the Journal of Inorganic Biochemistry and Inorganica Chimica Acta. Later I turned to environmental science and education, studying pollution, pro-environmental behavior, and how we teach people to live more healthily alongside the technology around them. What ties it all together is a question I care about deeply: how do we make sure the modern, engineered world doesn't quietly harm our bodies? That's the lens I bring to PickGrade. When a product touches your health — the air you breathe, the dust and allergens in your home, the chemistry of what a device actually filters or removes — I review the science behind the claims: what the numbers mean, which standards are real, and where marketing outruns the evidence. To be clear about method: I don't lab-test devices with my own hands, and I don't pretend to. What I do is hold manufacturer claims up against the underlying chemistry and independent research, so you can tell a genuine health benefit from a marketing one.
