I am a data scientist and finance "quant" with extensive experience in research, development and trading, and work at TileDB. I am also an (adjunct) Clinical Professor of Statistics at the University of Illinois teaching a topics course on Data Science Programming Methods.
Besides looking after a number of Debian packages, I write and/or maintain code for a number of projects: Rcpp and RInside; RQuantLib and several dozen more packages on CRAN. See the code link below for some more details.
