Research Interests

My research interests focus on understanding and developing treatments for the adaptive plasticity and maladaptive plasticity that occur following central and peripheral nervous system inflammation, damage, and disease. In particular, central nervous system mechanisms of pain and the therapeutic effects on them of combinatorial treatments that include manual therapy are to be investigated. Translating this information clinically so that pain's devastating impact on quality of life can be attenuated or alleviated is my ultimate goal.
