As people age, sometimes their ability to think and function properly starts to decline; the brain begins to degenerate and the individual’s cognitive abilities become impaired. This process is called neurodegeneration. It is not a normal part of aging, and we are very interested in trying to understand how and why neurodegeneration occurs and people lose cognitive function as they age. Neurodegenerative diseases, such as Alzheimer’s disease and vascular cognitive impairment, represent a huge health burden and are a leading cause of death and disability in the United States. It is thought these diseases include a significant inflammatory component, and epidemiological studies have demonstrated links between the typical Western dietary pattern (containing high quantities of sugar and fat) and chronic inflammation. Whether and how the inflammation that occurs in Alzheimer's and vascular cognitive impairment stems from our daily dietary habits presents an interesting question to investigate. We are particularly keen on investigating the mechanisms of diet-induced inflammation in brain blood vessels and how these processes may contribute to age-related neurodegenerative disorders. Blood vessels of the brain form an intriguing structure called the blood-brain barrier, which consists of endothelial cells, glial cells, and pericytes. This collaboration of cells tightly controls the brain’s environment, and thus is intimately involved in the health and proper functioning of the neurons in the brain.
We use human cell culture models to investigate the cellular pathophysiology underlying Alzheimer's and vascular cognitive impairment. We use molecular biology, biochemical, and imaging techniques to investigate the cellular responses to dietary insult in an effort to understand how the physiology of the cells is altered in the presence of different nutrients. We strive to explore how constituent cells of the blood-brain barrier communicate with each other, and in turn, communicate with neurons of the brain (or negatively alter the brain environment.) Student research interns in the lab will learn basic mammalian cell culture techniques, and will also learn molecular biology, immunocytochemistry, or biochemistry techniques in accordance with the current project aims of the lab.
Other Professional Interests
One of the most important attributes employers and graduate/professional programs look for when evaluating candidates is the ability to work well in a team. Opportunities to develop the collaborative and leadership skills necessary to achieve successful teamwork form a crucial part of the academic experience. Sacramento State hosts the Hornet Leadership Program (HLP,) which offers multiple opportunities for Science, Technology, Engineering, and Mathematics (STEM) students to explore their leadership capacity and develop leadership skills. Check out the ways to get involved with HLP here!
