Marshall Brennan manages ChemRxiv, the preprint server for chemistry. He has overseen the development of the service in its first year and worked to increase chemists' understanding of what open science can do for their research. He has personally handled the 800+ preprints on the server and runs the social media accounts @ChemRxiv and @Organometallica. Before coming to ChemRxiv, Marshall was a physical organometallic chemist specializing in making first-row metals contort into odd shapes in order to imitate noble metals and served as an associate editor for Nature Chemistry. He lives in the Washington, D.C., metro area and is not-so-secretly obsessed with movies and technology!
