Professor María Victoria Fonseca is chair of the MAGIC Collaboration Board, and Professor José Luis Contreras coordinates the MAGIC telescope’s Onsite Analysis pipeline. Meanwhile, Professor Marcos López is a convener of the Galactic Physics group and responsible for its Monte Carlo simulation software.

Regarding the involvement in CTA, Professor Juan Abel Barrio coordinates the Trigger & Clock working package in the CTA MST-NectarCAM project. Simultaneously, Professor Contreras has been responsible for the Data Model working group in the Data Management team.

Daniel Nieto, an associated professor and research scientist in the group, is the convener of the Machine Learning effort in the Analysis and Simulation working group.
Finally, Alberto Domínguez, a Ramón y Cajal fellow, is coordinating the activities of the AGN Science group of the Fermi-LAT collaboration.
Collaborations
The GAE collaborates with other Astroparticle Physics groups both nationally and internationally. As mentioned before, there is a long history of experience in extensive collaborations such as HEGRA, AUGER, MAGIC and CTA.
Examples of such cooperation include, among others: the work in the Data Group in collaboration with the observatory of Paris, LAPP Annecy and MPKI Heidelberg, the development of a Trigger System for CTA Cameras along with CIEMAT, IFAE and ICC-UB researchers, and the work in Machine Learning for CTA with Columbia University.
