I have studied responses to injury in a variety of different organisms. The inflammatory response, needed for defense and healing, is of particular interest to me since excessive or prolonged inflammation is damaging. Cytotoxic chemotherapy is known to induce peripheral inflammation. In my research I have found that it also induces inflammatory signaling in the brain stem and in the hypothalamus, regions critical for signaling wakefulness and activity. I have found that cytotoxic chemotherapy suppresses hypothalamic orexin neuron signaling and this suppression is associated with lethargy/fatigue. Orexin agonists are in the final steps of FDA approval to treat narcolepsy, a disorder characterized by disrupted wakefulness and disrupted sleep. This therapy might be useful to treat persistent fatigue and disrupted sleep associated with cytotoxic chemotherapy, traumatic brain injury, or stroke. As a neuro nurse, my long term goal is to improve functional recovery from disorders affecting brain function. When I am not pursuing inflammation , brain function, and related symptoms, I enjoy yoga, bike commuting, running, gardening, and generating electricity with my solar panels..
