Research Program:

My research program follows two main paths. The first is the interplay between addiction and pain. I use animal models to explore and dissociate the analgesic (pain-relieving) from the addictive (reinforcing) properties of drugs. The second major focus is the role of the immune system in pain sensitivity. Using genetically-modified animals, it is possible to determine the contribution of discrete aspects of the immune system to pain and sensitivity.
