The ECS Data Science Showcase will highlight new electrochemical and solid-state research and the open source software and datasets that underpin the work. Research talks will be complemented by a demonstration on how others can access, use, modify, and improve the open-source tools and data associated with the research project. Because data science is a fast moving field, the Showcase will conclude with a "Late Breaking News" session to feature emerging electrochemical and solid state research that embraces open software and open data sets. Especially valued are contributions that feature early-stage research where alpha- and beta-testers can be solicited to improve new open research products. The organizers welcome direct email contact by prospective contributors to the Late Breaking News section, up to four weeks prior to the event.
