After publishing several articles in leading toxicology and ecotoxicology journals, he held several regulatory roles in the industry focusing on biocides, plant protection, REACH, and CLP with a proven track of successful registrations. He has experience with the endocrine disruptors assessment of plant protection and biocidal active substances under the current EFSA and ECHA guidance. He also helped design and study monitored numerous toxicological and ecotoxicological studies very often with very specific and difficult to be tested substances. Currently, he is at REGARTIS focusing on assessing the new CLP hazard classes.
