KPCC's Science Reporter
Jacob's time in journalism began when he was 16, when he'd skip high school to spend his days working on the mid-day newscast at KPFK in Los Angeles.
Since then he's worked at NPR in Washington, D.C., as a producer on "The Madeleine Brand Show" and "Take Two" at KPCC and as a reporter, covering the political and social impact of California's new marijuana industry.
Now, he's the science reporter for the station.
