Kathryn Hulick is a freelance writer, editor and former Peace Corps volunteer. She writes regularly for Science News for Students and Muse magazine. She has also published numerous nonfiction books on topics such as video games, artificial intelligence, energy technology and dinosaurs. Hulick's favorite part of writing about science is getting to speak with researchers in many different fields. Once, she spoke with an expert on parallel universes while he was shoveling snow from his driveway. Another time, she called a biologist who was out in the field in Africa, watching a herd of elephants. In addition to writing, she enjoys hiking, gardening, painting and reading. Hulick lives in Massachusetts with her husband, son and dog.
