I use data to power accountability journalism. That means digging through databases and public records to uncover stories about how your identity and zip code can affect the kind of justice you get in Southern California.
As a data reporter, my work spans different beats. I’ve covered the avalanche of outside money in local politics, spiking firearms sales, Los Angeles’ bicycle infrastructure, and police militarization. I helped build a unique database on police shootings in Los Angeles and San Bernardino counties for KPCC’s Officer Involved project.
I attended Macalester College and the UC Berkeley Graduate School of Journalism and got my start in journalism at KFAI Fresh Air Radio in Minneapolis.
