Postdoctoral research fellows

Rogelio Rodríguez González


Dr. Rogelio received his Ph.D. in physics in 2018 from the Autonomous University of Zacatecas (UAZ), México. He obtained his B.S. and M.S. degrees in physics from UAZ, in 2011 and 2013, respectively. After receiving his Ph.D., he joined Centro de Investigación en Ingeniería y Ciencias Aplicadas (CIICAp) from the Universidad Autónoma del Estado de Morelos as a postdoctoral fellow in August 2019. He joined 2D Materials Research Group as a postdoctoral research in September 2020. His current research project is focused on the transport properties in 2D materials such as graphene and silicene in complex structures, where he explored novel exotic effects in the physical properties like the self-similar quantum transport. He also joined National System of Researches (SNI) as national research Level C in January 2020.

José Alberto Briones Torres

Dr. José Alberto Briones Torres, is a Postdoctoral Researcher at LUMAT-UAZ, SNI Candidate, received his Doctorate in Basic Sciences from the Autonomous University of Zacatecas, his area of ​​specialty is Physics, particularly he studies the propagation of electrons through periodic and aperiodic systems based on two-dimensional and novel materials such as graphene and the graphene bilayer. Currently it seeks to establish and consolidate a line of research that involves Fano resonances, two-dimensional novel materials and alternative energies, especially low-dimensional thermoelectricity.

During his Master’s studies he implemented an unusual method for the propagation of electrons through bilayer graphene-based systems, the hybrid matrix method, this method manages to avoid numerical instabilities that occur in the transfer matrix method (the common method). This was achieved thanks to the mathematical formalism of Sturm-Liouville.

He has been Co-director of a bachelor’s thesis and a master’s thesis, both of which worked on bilayer graphene. He is the author of 5 publications in specialized journals with rigorous arbitration and also of a book chapter. He has more than 25 participations in national and international congresses and with 10 talks in seminars and / or conferences at the state, national and international level.

For almost 5 years he was a Teacher-Mentor helping students with academic lag at the UAZ Student Learning and Services Center. He has teaching experience at a higher level teaching subjects such as Linear Algebra, Classical Mechanics, Probability and Statistics, Differential Equations and Solid State Physics.

During his Doctorate, he obtained the 2018 Zacatecas Youth State Award in the area of ​​science and Technology and the Award for the Best Average of his Generation.


José Guadalupe Rojas Briseño 


Dr. Rojas-Briseño got his Ph. D from the “Instituto de Investigación en Ciencias Básicas y Aplicadas, Universidad Autónoma del Estado de Morelos (UAEM)”, working in excitonic states in cubic nitride alloys. His bachelor and master in physics were obtained at “Unidad Académica de Física, Universidad Autónoma de Zacatecas (UAZ)”, studying the Frobenius Formulae for the inversion of large matrices and nonlinear optics on AlGaAs/GaAs delta quantum wells, respectively. He has been in two postdoctoral research stays at UAZ. 

He joined the 2DMRG in 2020, studying the conductance, spin-valley polarization and magnetoresistance in silicene structures. The main goal of his project within the 2DMRG is to assess low-dimensional structures that can the basis to improve the spin-valley polarization and magnetoresistive properties of 2D materials. Moreover, temperature, disorder and non-collinear magnetization effects than can limit the performance of spin-valley polarization and magnetoressitive low-dimensional devices. 

Eric Jovani Guzman 


Dr. Guzman obtained his PH.D in Physics Sciences at the University of the Michoacan State (UMSNH), Mexico, with honorific recognition in 2019. He did his doctoral thesis on the topic of spintronic and ferromagnetic materials under the guidance (supervision) tutorial of Dr. Oracio Navarro Chávez prestigious researcher at Institute of Materials of UNAM, and Dr. Outmane Oubram researcher at Institute of Chemical Sciences of UAEM, Mexico. In particular, he studied the temperature of Curie of double perosvkite Sr2FeMoO6 and the thermoelectric effect in gated silicene superlattices. 

Recently, in 2020, Dr. Guzmán got a postdoctoral position to work with Dr. Isaac Rodríguez Vargas at LUMAT of the University of Zacatecas State (UAZ), Mexico. During this residency, he was carried out a profound study of the thermoelectric effect in aperiodic gated superlattices both in silicene and graphene and in collaboration with Dr. Sergio Molina Valdovinos researcher at LUMAT.

His area of research focuses on Materials Physics and Solid State topics. Especially in the study of the electronic and magnetic properties in 2-D materials for potential applications such as spintronic, ferromagnetic and thermoelectric devices. His experience as a professional researcher has been reflected through the publication of articles (papers) in high-impact scientific journals, as well as through the participation in national and international conferences.
