Contributions to Science
Since receiving my PhD, I have published over 300 papers primarily on the physiology of the cerebral. My major contributions are in many different areas, five of which are detailed below. In each area, I have summarized my studies and placed them into context by writing review articles. I was able to be successful in these areas due to interactions with excellent collaborators, with whom I share credit for our contributions to the advancement of science. Furthermore, I have trained many students, postdoctoral fellows, and visiting scientists in the area of the cerebral vasculature and they have done well.
1. Development of the cerebral circulation field. I was fortunate to have been present during the early days of development of studies on the cerebral circulation in which very little was known concerning regulatory mechanisms, and new approaches and methods were being developed. Since the field was wide open at the time, our studies were novel and broke new ground. Furthermore, together with colleagues, we were among the first investigators to extend studies of the cerebral circulation to the neonate in addition to adult animals. Finally, I have sustained my productivity in this field for almost 40 years and continue to receive invitations to speak during symposia and departmental seminars as well as to write comprehensive review articles.

2. Establishing an important role of eicosanoids in cerebral vascular control. Together with collaborators such as Dr. Charles Leffler at the University of Tennessee – Memphis, I was able to establish for the first time an important role — especially in the neonate — for eicosanoids, including prostaglandins, leukotrienes, and other metabolites of arachidonic acid, in regulation of the cerebral circulation during health and injury.

3. Elucidating mechanisms of protection of the brain. My laboratory was the first to demonstrate that selective targeting of mitochondria could protect the brain against anoxic/ischemic injury. In these pioneering studies, we first defined the consequences to the brain parenchyma and cerebral vasculature of ischemic injury and then developed novel approaches to prevent or remediate injury both in vivo and in cultured neurons, astroglia and endothelium.

4. Defining and preventing adverse effects of insulin resistance on the cerebral vasculature. Insulin resistance is an early stage in the development of the metabolic syndrome and previously was considered to be a “quiet” phase of the disease. In our studies, we showed for the first time in a comprehensive manner the adverse consequences of insulin resistance on the cerebral, mesenteric, and coronary arteries and developed new approaches for treatment and alleviation.

5. Establishing an important role of mitochondria in cerebral vascular control. My laboratory was among the first to show that mitochondrial mechanisms are important in the regulation of the cerebral circulation under normal conditions. Furthermore, we were able to show that mitochondrial influences from diverse cell types of the neurovascular unit, including neurons, endothelium, and vascular smooth muscle, are able to contribute to an integrated vascular response. We believe that mitochondrial influences are the elusive link coupling brain metabolism to blood flow. Lastly, we were the first laboratory to show that disease states such as insulin resistance and experimental strokes have complex effects on mitochondrial-derived vascular responses.
