I am a researcher in the fields of operations research and computational social science.
For development I mostly use Julia language.
I am one of the maintainers of DataFrames.jl.
DataFrames.jl provides a comprehensive set of functions that allow performing transformations of tabular data using an operation specification language. This language lets users pass columns from a source data frame, a function to apply to them, and column names to store the result in the target data frame. In this workshop, I will explain the functionalities that it provides. Here you can find workshop materials.
