Hello! I am a biostatistician and R developer in the Department of Biostatistics at Vanderbilt University Medical Center. My primary collaboration is with the Vanderbilt Memory & Alzheimer’s Center, a team of clinicians and scientists committed to uncovering how cardiovascular health affects Alzheimer’s disease pathology and cognitive decline in older adults. I use the R programming language to conduct statistical analyses that employ a modern approach. Methods I commonly use include mixed-effects regression models, nonparametric bootstrap resampling, and mediation analysis. I like using R because I’m able to combine R code with Markdown, $\mathrm{\LaTeX}$, and JavaScript to create dynamic, reproducible reports; it has an active community of open-source developers that I love participating in; and it is a functional programming language that is fun to use.

In addition to conducting statistical analyses, I create software tools that address unique challenges arising from collaborations between statisticians and other scientists. Examples of these tools include a research package that automates the highly complex process of generating a master dataset, a package that allows the user to create a codebook to accompany the sharing of a dataset, and a web app that lets users perform basic exploratory data analysis without needing to write any code or submit a statistical request.

Outside of my work, I like to study languages, cook, and play video games. Please feel free to shoot me an email if you would like to chat!
