Biography

Cecilia Hillard is a leading expert in endocannabinoid biochemistry and the role of the ECS in stress responses and psychiatric disorders. Her laboratory has made foundational contributions to understanding how stress regulates endocannabinoid signaling, and how disruptions in this system contribute to anxiety, depression, and PTSD. Hillard's work on the relationship between circulating endocannabinoid levels and psychiatric symptoms has opened new biomarker opportunities for cannabinoid-based therapeutics.

Key Contributions

  • 1Characterized the role of endocannabinoid signaling in stress adaptation and resilience
  • 2Demonstrated that circulating 2-AG levels are a biomarker of stress reactivity
  • 3Identified sex differences in endocannabinoid signaling with implications for PTSD treatment
  • 4Developed methods for measuring endocannabinoids in human blood and CSF
  • 5Showed that chronic stress depletes endocannabinoid tone, contributing to anxiety and depression

Selected Publications
