Wald, Chelsea: - Chelsea Wald has repeatedly plunged into the topic of toilets since 2013, when editors first approached her to write about the latent potential in our stagnating infrastructure. Since then she has traveled to Italy, South Africa, Indonesia, and Haiti, as well as throughout the Netherlands and the United States, in search of the past and future of toilet systems. With a degree in astronomy from Columbia University and a master's in journalism from Indiana University, Chelsea has more than fifteen years of experience in writing about science and the environment. She has won several awards and reporting grants, including from the Society of Environmental Journalists, the European Geosciences Union, and the European Journalism Centre. She cofounded and continues to help coordinate the DC Science Writers Association Newsbrief Awards for short science writing. She lives with her family in the Netherlands, in a region renowned for its water-related innovations.
