Estrin was the driving force behind Lens, and has been its co-editor since it went online in May 2009. He started at The Times in 1987, and was part of the team that won a Pulitzer Prize in 2001 for the series “How Race is Lived in America.” In 2004, he was the first journalist to photograph an assisted suicide in Oregon, an event which he documented through articles, photographs and an audio slide show. Internationally, he has covered the Israeli-Palestinian conflict several times and chronicled the journey of Mexican immigrants who shuttle between their lives in the United States and Mexico.
