Stella Fragki joins esqLABS

Stella Fragki, an experienced human toxicologist, joined esqLABs on 1st January.



Stella Fragki joins esqLABS

Stella will support esqLABS in toxicology and regulatory risk assessment.

Styliani (Stella) Fragki is a human toxicologist who is passionate about promoting the use of alternatives to animal testing in chemical safety. She has several years of experience in toxicological risk assessment and she has provided support to the (agro)chemical industry with regard to their dossier preparation for plant protection products, biocides, and substances falling within REACH since 2010. She also worked for the Dutch government (RIVM-National Institute for Public Health and the Environment) as a scientist in the safety of substances entering the food chain (food contaminants, food contact materials, botanicals, etc.), but also in the application of New Approach Methodologies (NAMs) in chemical risk assessment. She joined esqLABS in January 2023 as a Senior Scientist Systems Toxicology. She has studied Biology (Thessaloniki, Greece) and she has an MSc in Food Safety (Wageningen, the Netherlands). Stella recently finalized her Ph.D. thesis in toxicology, specifically on the quantitative in vitro to in vivo extrapolations (QIVIVE) of alternative assays with physiologically based kinetic (PBK) models, parameterized with data based on in vitro and in silico tools. She has completed the full training for a European Registration as a Toxicologist (certification to be obtained soon).
