I’m Betsy Ladyzhets, a data journalist and science writer. I currently work as a Senior Research Associate at Stacker, where I do data reporting and manage the publication’s science, health, and lifestyle content. I’m also a volunteer for the COVID Tracking Project at The Atlantic; I’m a Shift Lead on the Data Entry team. My newsletter, the COVID-19 Data Dispatch, brings together my experience from both these roles with news, resources, and original reporting on COVID-19 data sources. I’m also available for additional freelance work. My past work has appeared in outlets including Science News, The Open Notebook, and the communications of Black Rock Forest.
