Erin Garcia de Jesús is a staff writer at Science News. She holds a Ph.D. in microbiology from the University of Washington, where she studied virus/host co-evolution. After deciding science as a whole was too fascinating to spend a career studying one topic, she went on to earn a master’s in science communication from the University of California, Santa Cruz. Her writing has appeared in Nature News, Science, Eos, Smithsonian Voices and more, and she was the winter 2019 science writing intern at Science News.
