While the Supreme Court considers the future of Roundup liability, a leading epidemiologist with 20+ years of research says the real issue is that U.S. pesticide policy still hasn’t caught up to decades of scientific evidence.


Dean Perry can speak to:

  • What 20+ years of epidemiological evidence tells us about pesticide exposure and disease risk 
  • Why current regulatory frameworks may not reflect modern science (especially around chronic, low-dose exposure) 
  • How increasing pesticide use and resistance are shaping long-term public health risks 
  • What policy changes could better align regulation with current evidence 

“For more than two decades, the science on pesticide exposure has been consistent and compelling. We can measure exposure in real time, and we have a large and growing body of evidence linking these exposures to cancer, endocrine disruption, and neurological disease. The gap is no longer in the science—it’s in the policy. Regulatory frameworks still rely on outdated models that don’t fully account for chronic, low-dose, and cumulative exposures. It’s time for policy to catch up with what the evidence has been telling us for years,”
