A particular focus of my work is devising efficient, in terms of computational complexity and implementation, algorithms and tools for applying the methods I develop to prominent data-analytic scenarios. I also engage in designing and implementing principled data analysis pipelines for application domains (e.g. sports).

Below is a list of the software I have (co-)developed and (co-)maintain in these directions.

cranly directives network for my R packages

Below, I am using my R package cranly to quickly build the directives network for my R packages.
