During the last few years, I have hardly shown any activity on this website. This is because they have coincided with periods of considerable intensity, especially in terms of work. I already wrote about one of the main reasons, and today I would like to write about another other one: Accessible Zaragoza, the collaborative mapping project of aspects related to urban mobility and disability that I devised in the academic year 2015-16 within a chair at the Universidad San Jorge and in which I have been working as a principal investigator since then.
