Biography

Cristian Vacacela Gomez obtained his PhD in Physics & Quantum Technologies in the field of Condensed Matter Physics and Quantum Mechanical simulations from the University of Calabria, Italy, in 2017. For his PhD studies, he was the winner of one SENESCYT scholarship in 2012. In 2017, Cristian became a Research Professor at Escuela Superior Politécnica de Chimborazo for two years, teaching Computational Physics and Quantum Mechanics. Finally, in 2019 Cristian joined the School of Physical Sciences and Nanotechnology at Yachay Tech University as Research Professor.
