Profesores Actuales

Como docente de la carrera de Pedagogía en Física y Matemática/Licenciatura en Educación de Física y Matemática, mi principal objetivo es formar y preparar a nuevos profesores con las habilidades y herramientas necesarias para enseñar de manera efectiva y contribuir al desarrollo académico y social de la sociedad. Para lograr esto, proporciono a mis estudiantes una educación de calidad, con una sólida base teórica y práctica, que puedan aplicar en su futura labor docente. Además, desarrollo labores de investigación en Física de la Materia Condensada, con el objetivo de obtener nuevos conocimientos que puedan tener aplicaciones tecnológicas en el futuro, como el almacenamiento de información en equipos tecnológicos, la arquitectura de ordenadores neuromórficos y los sensores magnéticos. De esta manera, espero seguir aportando al avance y desarrollo de la ciencia y la tecnología en la sociedad.

Mi trabajo en la Universidad contempla labores de docencia en pre y postgrado, investigación y administración. La investigación la desarrollo en el área de los ultrasonidos de potencia y señal, tanto en investigación básica como aplicada, destacando trabajos aplicados en la industria minera y de procesos. Trabajo en temas de protección de la propiedad intelectual por mi formación en las oficinas de patentes de Europa y Japón. ​Publicaciones:
