Relatively permanent changes to the nervous system occur in response to environmental conditions imposed upon an organism, including stimulus characteristics, behavioral processes, or neural insult. I am interested in the response of the central nervous system to insult specifically traumatic brain injury or stroke. These types of injury are two of the leading causes of death and disability in the United States, for which there are few effective treatments.

One of the major consequences of neural insult is neuroinflammation. This cascade can be both beneficial and detrimental, and there is much to be learned about the dynamics of this complicated response. It is characterized by increases in pro and anti-inflammatory cytokines, leukocyte invasion, blood-brain barrier permeability, and glial activation. Astrocytes and microglia are glial cells that are activated following injury and have been shown to regulate the immune response. I am interested in elucidating the multicellular neuroinflammatory response in hopes of developing therapeutic treatments for central nervous system damage.

In particular, I am interested in studying the neuroinflammatory response to stroke, which is exacerbated following stroke. Obesity is a serious chronic inflammatory disease. People who are obese are 65% more likely to have a stroke. The interaction between this peripheral inflammatory condition and the neuroinflammatory response following stroke has not been well studied. I am interested in defining the underlying mechanistic underpinnings of the increased neuroinflammatory response seen in the obese. Shedding light on this process will lead to potential therapeutic treatments for stroke in the obese.

I grew up in the Midwest, but I have quickly been adapting to the beach lifestyle. When I am not working vigorously in the laboratory, I enjoy many sports including long distance running, volleyball, snowboarding, and most water sports (wakeboarding, kiteboarding, and surfing).
