A Grammar for Hypothesis Testing in the Tidyverse

I work with Andrew Bray Ph.D. on {infer}, a widely used R package providing a framework for hypothesis testing in the R tidyverse setting that emphasizes the underlying intuition behind "statistical significance."

An Alternative to Rankings-Based College Exploration

Newsmagazine college rankings like those provided by U.S. News are both unhelpful for prospective students and reinforce existing status obsession. As an alternative, we developed a data-centered tool that focuses on what makes a college similar to, not better than, another college.

Differentially Private Nonparametric Hypothesis Testing

Proceedings of the 2019 ACM SIGSAC Conference on Computer and Communications Security - London, United Kingdom

Our group developed a new class of privacy-preserving hypothesis tests, largely analogous to the non-parametrics in conventional statistics, that drastically improves on all existing differentially-private tests intended for the same use cases.

Encouraging Equitable Bikeshare

In making use of my R package {gbfs} to scrape latitude/longitudes of over 45,000 bikes across the country and joining that data with census demographic data, this project set out to determine the characteristics of a community that are most salient in understanding the spatial distribution of bikes, and how these interact with different operating models of bikeshare programs. A preliminary report on this research tied for second place in the ASA-sponsored “Undergraduate Statistics Research Competition.”

Gendering Code Documentation

Through interviews with women in statistical computing, as well as quantitative analyses utilizing web scraping and text mining methods, I argue that code documentation in the tidyverse is written more effectively and inclusively than other R code documentation, and that this is meaningful for understanding gender representation in the user community.

Social Divisions in Data

I argue that, rather than viewing datasets as unargumentative, sterile, or “raw,” datasets express and reinforce the social conceptualizations held by their authors. More specifically, in this paper, I examine how sex, gender, race, and ethnicity are named and encoded as variables in data, and how this process is patterned by identities held by the datasets’ authors.

Race, Differential Privacy, and the 2020 U.S. Census

This project examines the racialized implications of the U.S. Census Bureau's decision to implement differentially private count estimation algorithms to estimate subpopulation sizes in the 2020 U.S. Census.
