Area of Expertise

Steven Levine has a Doctorate in Environmental Toxicology with expertise in ecological risk assessment, mechanistic toxicology, endocrine disruption, and mixtures. Recently, his work focuses on testing and assessing conventional pesticides and biotechnology derived insect-protected crops to support global registrations and re-registrations.

Steven’s initial interests in studying the physiology and ecology of aquatic animals ultimately motivated him to pursue a career in Environmental Toxicology. His experience as a biologist in fisheries led him to take on a larger role working with mammalian and aquatic toxicologists, eventually catalyzing his graduate research degrees and Fellowships through EPA and NIH in Environmental Toxicology. Based on his training and research experience, stewarding the development and commercialization of pest control solutions was an excellent fit for his skill set and interest in contributing his expertise to support sustainable agriculture.

Review and analysis of the potential for glyphosate to interact with the estrogen, androgen and thyroid pathways

Endocrine (AKA: hormone) systems are found in all mammals, birds, fish, and many other organisms. These systems are essential for regulating hormones in the bloodstream to influence growth, development, reproduction, metabolism, and energy production. Scientific research suggests that some environmental contaminants can disrupt the endocrine system leading to adverse consequences. This recent paper consolidates available information analyzing the potential effect of glyphosate on the endocrine system, finding that glyphosate is not an endocrine disruptor.
