Research Interests

  • Neural Mechanisms of Pain Modulation
  • Animal models of opioid withdrawal

Pain is the most costly medical problem in the United States. Pain treatments are limited by poor analgesic efficacy or severe side effects (e.g., opioid dependence). My lab uses behavioral pharmacological approaches to address this problem in three ways: First, we are developing new ways to assess pain in animals such as measuring depression of activity (e.g., decreases in wheel running) to more closely mimic the effects of pain in people. Second, we are studying how the midbrain periaqueductal gray contributes to opioid analgesia and tolerance. Third, we are developing novel methods to assess spontaneous opioid withdrawal in rats in order to create a better model of opioid withdrawal in humans. Our primary goal is to lay the groundwork for the development of more effective treatments for pain and opioid withdrawal.
