Current projects:

1) Investigation of Neural Mechanisms Underlying Seeking Behavior

Goal: Identify underlying mechanisms involved in sodium-induced cross-sensitization of reward systems and seeking behaviors


Public health relevance: Salt is perhaps the most frequently abused substance in modern society. Because emerging evidence implicates the endogenous opioid system in salt appetite and need-free sodium intake, an unmet need exists for the identification of opioid-mediated mechanisms that prime reward circuits to support salt addiction. This project will use the primal need that mammals have for salt as a novel means to access and reinforce the circuit elements, as well as neurochemical and synaptic mechanisms, that promote addiction and seeking behavior for a variety of rewarding substances, especially illicit drugs.

2) Sleep Apnea & Opioid-induced Respiratory Complications

Goal: Investigate neurocircuitry underlying the propagation of sleep apnea-related opioid-induced respiratory depression


Public health relevance: There is an important interrelationship between opioids, sleep apnea, and overdose. Given that chronic opioid use dose-dependently increases sleep apnea in humans and that sleep apnea increases opioid sensitivity, patients with sleep apnea have a high risk in the clinic for opioid-induced respiratory depression and subsequent overdose. Thus, an unmet need exists to identify the neurocircuitry that underlies the propagation of sleep apnea-related opioid-induced respiratory complications. Understanding these neurochemical and synaptic mechanisms may lead to identification of safer therapeutic options for this patient population.
