Software

Complex data and complex processes call for complex statistical methodology. Complex statistical methodology requires complex tools. As a part of the Statnet Project and otherwise, I seek to put sophisticated network analysis methodology into the hands of subject-matter researchers by providing robust, flexible, user-friendly, and well-documented software packages.

To facilitate reproducibility and validation of results, I aim to not only implement methodology that I have developed or co-developed but also state-of-the-art methodology developed by others.

My software work has been recognised with a number of awards. Most of these packages have introductory workshops.

I am also a co-creator and co-maintainer of the CRAN Task View on Network Analysis, with Fabio Ashtar Telarico, James Hollway.
