+The workshop will be a great opportunity to discuss and exchange ideas, share ROOT usage experiences, learn about new features and shape the future of the project together. In particular, we will focus on the following topics: Analysis, I/O & Storage, Math and Stats, and Scientific Python Ecosystem.
