Between 2009 and 2020, Ganuza was Research Fellow at the Institute for Advanced Social Studies in the city of Córdoba.
He worked on citizen participation in a broad sense, from the history that favours its implementation, to the analytical elements that allow us to better understand the conditions that favor participatory institutions.

He has taught in the Master of Participatory Methodologies at UCM.

He was the coordinator of the first Deliberative Survey organized in Spain on Water in Andalusia (2008) and advised the City Council of Córdoba to design and organize Participatory Budgeting (2000).
