I investigate health care.

Have a Tip for a Story?

Please send me tips and information on subjects in need of investigating.

What I Cover

I investigate health care. This includes pharmaceutical and medical device makers; researchers and providers; major hospitals and academic medical centers; and the health insurance industry.

My Background

I joined ProPublica in March 2018, and I have reported on the flawed science employed by experts testifying in child abuse cases, the fundraising practices of St. Jude Children’s Research Hospital and the ways in which health insurers deny care. Previously, I was the senior enterprise reporter for STAT, where I wrote about abuses in the addiction treatment industry, the rise of fentanyl and the recruiting of college football players with histories of concussions. At The Wall Street Journal, I was part of the team awarded the 2002 Pulitzer Prize for breaking news reporting on the attacks of Sept. 11. As a staff reporter at The Boston Globe, my investigation with colleagues of safety flaws in escalators won the George Polk Award and the Investigative Reporters and Editors award.
