Lauren Lipuma works in AGU’s public information department. She communicates new AGU Earth and space science research to journalists and the public through press releases, blog posts, photos, videos and more. Before focusing on science communication, Lauren worked at Memorial Sloan-Kettering Cancer Center in New York, where she studied the immune response to infectious diseases and did extensive research on the bacteria that make up our poop. She worked as a staff writer for a monthly medical magazine and in wildlife conservation prior to joining AGU in 2015. Lauren is a past president of the DC Science Writers Association.

Olivia V. Ambrogio is the manager of the Sharing Science program at AGU, where she does her best to help other scientists connect with wider audiences. She is a biologist by training who got her Ph.D. studying the sex lives of marine snails. In spite of the surprising allure of this research, she eventually shifted into the field of science communication. In her spare time she writes and takes nature photos, often frustrating her partner and friends (who just wanted to take a walk) by crouching on the ground to photograph an insect.
