Analysis of detained child migrant data
As a data science fellow at the Human Rights Data Analysis Group, I analyzed a leaked dataset about children held in detention centers between 2013 and 2018. I found that childrens’ dates of entry into detention are generally positively correlated with their assigned alien numbers. I wrote about the implications of this finding for population estimation and the security of sensitive data about children. I also conducted a modeling project about the codes of categories that detention centers use to classify incidents that occur to chilren, from trauma from border crossings to physical assaults. I used latent Dirichlet allocation to identify topics in the incident descriptions, and random forest classification to predict the category codes when they were missing in the original data.
The Tracker is a landmark data and news website that aims to document every press freedom violation in the United States, from border stops to physical attacks and subpoenas for sources. I produced reporting on these incidents, conducting interviews with journalists, law enforcement, prosecutors, and witnesses when relevant, and often used court records in my reporting. I also contributed to the development of the Tracker website. I spoke with my colleague Alexanda Ellerbeck (Committee to Protect Journalists) at Hackers on Planet Earth (HOPE) about the Tracker in the summer of 2018.
A database of law enforcement officers in Chicago, the East Bay, and New York City built using public records and crowdsourced data. I brought the project to the East Bay and to New York City, and contribute code, documentation, obtain rosters through FOIA requests, and assist in populating the database with officers, photographs, and incidents. I spoke with my colleague Jennifer Helsby at OpenOversight at Hackers on Planet Earth (HOPE) in the summer of 2018.
