I am a senior data scientist / engineer and "quant" with extensive experience in research, development and trading, and work at TileDB (and we're hiring). I am also an (adjunct) Clinical Professor in Statistics at the University of Illinois Urbana-Champaign where I created and teach STAT 447: Data Science Programming Methods.

I have been contributing to open source, mostly Debian and R, since the 1990s. Besides looking after numerous Debian packages, I develop and/or maintain a number of projects, many around R, often involving C++ and making use of Rcpp, a package I started and project I head. The code link has more details. I am also a co-creator of the Rocker Project bringing Docker to R.

The work on Rcpp led to a book in Springer's useR! series. Links to other publications are below (or see Google Scholar), as are slides from talks, workshops or lectures.
