Research Interests and Project Expertise

Methods Development; Data Management and Visualization; R Language for Statistical Computing; Human Variation


I am a biological anthropologist broadly interested in human evolution and human variation. Throughout my career I've developed a quantitative focus developing tools (usually in R) to facilitate and streamline data analysis. I have contributed to research labs studying growth and development, comparative anatomy, the menstrual cycle, baboon evolution, and fossil reconstruction. When not coding, I enjoy spending time with my cats, cooking, and hiking. I joined IPUMS in 2021 to help improve the data intake pipeline by developing new tools and programing using R to facilitate data processing and reformatting.
