  • Litter effects in multigenerational perinatal exposure studies

Rodent Toxicity Studies

  • Optimal design of dose range finding studies
  • Nonlinear dose-response models
  • Estimation of toxic equivalency factors (TEFs)
  • Analysis of chemical mixtures
  • Physiologically based pharmacokinetic (PBPK) models
  • Estrous cyclicity analyses

High Throughput Screening (HTS)
