Ari Sen

I'm a journalist based in Washington, D.C., where I serve as data editor at Scientific American. My reporting uses computational methods to investigate policing, technology and public health.

Previously, I was an investigative data journalist at CBS News, where I spearheaded an investigation into criminal police officers who work off-duty jobs. Before that, I was a computational journalist on the investigative team at The Dallas Morning News, where I was voted Investigative Reporter of the Year in my first year on the job. I started my career as an intern at NBC News, where I co-authored a series that led a senior State Department official to resign.

My work has won an IRE Award, a Livingston Award nomination, an Online Journalism Award and recognition from the National Association of Science Writers. I was a member of the inaugural cohort of Pulitzer Center AI Accountability Fellows.

I have a master's degree in journalism from UC Berkeley and a certificate in applied data science from the UC Berkeley School of Information. I did my undergrad in journalism at UNC-Chapel Hill.
