Meghan Rosen

Senior Writer

Meghan Rosen is a senior writer who reports on the life sciences for Science News. She earned a Ph.D. in biochemistry and molecular biology with an emphasis in biotechnology from the University of California, Davis. Her dissertation work involved studying mutated proteins in liver and kidney cancer. She later graduated from the science communication program at UC Santa Cruz. Prior to joining Science News in 2022, she was a media relations manager at the Howard Hughes Medical Institute. Her work has appeared in Wired, Science, and The Washington Post, among other outlets. Once for McSweeney’s, she wrote about her kids’ habit of handing her trash, a story that still makes her (and them) laugh.
