My programming environment of choice is R, because it is a high level software and it automatically does memory management when creating objects. It is the sort of language where users can focus on substantive issues, rather than pure programming.

The most important R package I’ve created is called QCA, which does Qualitative Comparative Analysis for all types of input data: binary crisp, multi-value crisp and fuzzy sets. This package is now used in many universities and summer schools all over the world.

I am currently working with Ciprian Păduraru on producing a parallel version of the minimization algorithm, which has the potential of increasing the execution speed function of the number of cores from the machine where the package is installed.

Linked to QCA is an independent package called venn, that creates Venn diagrams for up to 7 sets. It is specifically written for graphing entire sets or any other custom intersection, specified as a SOP (sum of products) expression.

Interpreting SOP expressions, as well as a good number of useful miscellanea functions, are tasks perfored by the admisc package.

Another incipient package that has a lot of potential is called DDIwR, with a number of useful functions based on the Data Documentation Initiative standard.

Together with Emilian Hossu, I currently develop an new type of Graphical User Interface generator for R, creating custom dialogs that are imported in a main application, employing ElectronJS from the node.js environment. It uses webkit as a standard environment, so the created dialogs look exactly the same on the users’ machines. As an added bonus, this is achieved irrespective of their operating systems, because the dialog objects are created from scratch using the magic of Scalable Vector Graphics provided by the RaphaëlJS library.

At the Department of Sociology, I teach the following classes:

• Descriptive Statistics
• Inferential Statistics
• Measurement in the social sciences

My preferred e-learning platform is Moodle, where students complete quizzes and build their final grade throughout the entire semester.

In my limited spare time I offer consultancy on topics related to sampling, basic statistical analysis and social research methodology. A significant part of my current training is dedicated to the R environment for statistical analysis and data management.
