Our lab studies aging and Alzheimer’s disease.

We are interested in understanding the interplay of factors that contribute to healthy or pathological brain aging. In particular, the effect of factors that contribute to or protect against the development of Alzheimer’s disease.

We use a number of tools in our research, including cognitive testing, MRIPET, and CSF analysis, to determine how risk factors for Alzheimer’s affect the brain, particularly in mid-life.

13 bacterial genera identified as differentially abundant in AD were correlated with CSF biomarkers of AD including the Aβ42/Aβ40 ratio (with lower CSF levels reflecting greater amyloid deposition in the brain), phosphorylated tau (p-tau), and the p-tau/Aβ42 ratio. From Vogt et al., 2017 published in Scientific Reports.

Our NIA funded research program is focused on characterizing the early effects of Alzheimer’s disease on brain myelin and axons, in addition to determining the role of preclinical inflammation in cell and dendritic damage.

Together with collaborators both on and off of the UW campus, the lab is also studying the impact of modifiable factors that may affect trajectories of aging. These include the effect of mid-life metabolic disorders (obesity and insulin resistance), sleep, diet, and microbial influences.

Understanding early brain changes in people who may go on to develop cognitive decline is expected to lead to earlier diagnosis, prevention, and the development of new therapies for Alzheimer’s disease.
