A message from the chair

Our faculty and students are uniquely positioned to tackle the profound global challenges posed by environmental contaminants and stressors, including climate change, which threaten public health. Our faculty engage in high-impact and diverse research — from laboratory- and field-based environmental health science to broader big-data-driven and translational sciences. This research recognizes the global environmental burdens that impact people and ecosystems worldwide. We are deeply committed to applying the principles and practices of environmental health to a "One Health" approach to teaching, research and practice. Now more than ever, environmental health researchers and practitioners are needed to address a myriad of environmental challenges that pose health threats in workplaces and communities.
