I’m Noah Greifer (pronounced gree-fur; pronouns: he/him), a statistical consultant and programmer at Harvard University. I provide statistical consulting services as a member of the Data Science Services team at the Institute for Quantitative Social Science (IQSS) at Harvard. I also develop R packages, both as part of my job and in my personal time. Some of these packages include MatchIt, WeightIt, and cobalt, which facilitate the use of propensity score methods. See my other packages at the Software link above. I post on my blog about R programming, statistical analysis, and R package development. I am active on Bluesky and CrossValidated.

I currently reside in Cambridge, MA, but I grew up in Los Angeles, CA, and have lived in San Diego, CA, Portland, OR, and Durham, NC.
