Cristian Velasco

Graduated in Physics at the Universidad de Valladolid. M. Sc. Degree in Instrumentation of physics during the academic course 2014-2015. He has a PTA (Personal Técnico de Apoyo) contract partly supported by the MINECO and GOA, the group support a 20% with his salary. His mission into the group is to attend the work of calibration and maintenance (repair, cleaning, etc.) of RIMA Cimel sun photometers, what also means maintenance of the field calibration platform at Science Faculty (University of Valladolid) and the Optics laboratory.
