I’m a research reporter at ProPublica based in New York.
Have a Tip for a Story?
What I Cover
I cover a wide range of stories as a part of ProPublica’s national team. Most recently, I’ve contributed to investigations of the Supreme Court and the federal judiciary, as well as President Donald Trump’s business dealings.
My Background
I’ve worked with both local and national teams at ProPublica, where I’ve been a research reporter since 2020.
My work alongside colleagues in the newsroom has spurred change, driven news cycles and won awards. In 2024, my colleagues and I received the Pulitzer Prize for public service for our work revealing ties between Supreme Court justices and billionaire benefactors. Our stories helped lead to the court establishing a code of conduct — a first in its history. Our work also won a George Polk Award, the Selden Ring Award and an Investigative Reporters and Editors medal.
Prior to ProPublica I was a post-graduate reporting fellow at the Columbia University Graduate School of Journalism.
