Nicholas St. Fleur

Award-Winning Science Journalist

and Children's STEM Author


About Me


Nicholas St. Fleur is an award-winning freelance science journalist and a children's STEM author based on Long Island, New York. He is also a Knight-Wallace Reporting Fellow with STAT covering the intersection of race, medicine, and the life sciences.


He has written more than 350 stories for The New York Times and is a regular contributor to the science desk's Trilobites column. He reports on archaeology, paleontology, human evolution, natural history, space, and other curiosities of the cosmos. His other areas of interest include citizen science, K-12 STEM education, and diversity in science.


In March of 2020, he published his first children's book, "Did You Know? Dinosaurs" (DK Publishing and the Smithsonian).

Mr. St. Fleur joined The New York Times in 2015 and worked as a staff reporter on the science desk for three years before moving to California. As a freelancer, he continues to write for the science section, as well as for The New York Times for Kids and other publications.

While at the Times, he was a lead reporter covering the 2017 Great American Eclipse. In 2018 he received the Gene S. Stuart Award from the Society for American Archaeology for the feature story “Medical Tales from a Crypt in Lithuania,” and for his coverage of mummies, pyramids, and shipwrecks. He also received an honorable mention from the D.C. Science Writers Association's 2017 Newsbrief Award for his story "Newly Discovered Gecko Escapes Danger Naked and Alive."

Prior to joining The Times, he reported for The Atlantic, where he covered everything from space probes on comets to protests on the New York City streets. He has also written for Scientific American, Science Magazine, NPR, and The San Jose Mercury News.

Mr. St. Fleur graduated from Cornell University, where he studied biology, minored in communication, and served as the science editor of The Cornell Daily Sun. He completed his graduate work in science communication at the University of California, Santa Cruz.

Video, Speaking, and Virtual Visits


I am always looking for opportunities to share science stories through multimedia.

For The New York Times, I have filmed more than a dozen Facebook Live science videos. Several of those videos were shot aboard a research vessel 100 miles off the coast of Maine. There, I documented marine scientists as they ventured to the seafloor in the Alvin submersible. I have also helped craft scripts for The NYT's science video series, ScienceTake about brewing homemade explosive lava, and a cockroach's karate kick.


I also enjoy speaking with classrooms and other groups about being a science reporter and the craft of science writing. If you would like to have me virtually speak with your classroom or group, please send me an email at for more information.
