Dr.C. Alejandro Lage Castellanos, director of the Center for Complex Systems of the Faculty of Physics of the University of Havana (UH), spoke with professors and students from research groups of our house of higher studies.

Lage Castellanos gave the conference Population Mobility and Big Data (data intelligence) with the intention of stimulating research and joint collaboration between both centers.

The physicist by profession outlined basic ways to generate and store large amounts of data for analytics, an act of processing that has been around for a long time and that he called "a new kind of science."

He spoke in a short time about the projects they have been working on since the beginning of the COVID-19 pandemic in our country and that were essential for the reduction of cases due to contagion and for epidemiology studies.

He exemplified the models to know the mobility behaviors of people in the country, which are generated in correlation with data from mobile phones and cell signal towers of the Cuban Telecommunications Company (Etecsa).

In this sense, the director assured that with access to telephone records in Cuba, the privacy of the data is guaranteed, since they are kept anonymous.

In summary, the young researcher shared ideas about the statistical analysis of behaviors in which large volumes of data are used and the projects that have the possibility of being developed with institutions such as the National Office of Statistics and Information (Onei) and the Ministry of Transport. (Mitrans), in the latter to investigate transportation flows and the development of GPS and tracking applications for the state and private sectors.

The meeting concluded with an avid exchange between the researchers present, led by Dr.C. Héctor Raúl González Diez, director of Science, Technology and Innovation at this higher education center.
