Prof. J. Montoya-Cardona received his B.S. degree in telecommunications engineering from the Instituto Tecnológico Metropolitano (ITM), Medellín, Colombia, and his M.Sc. degree in physics (optics) from the Center for Scientific Research and Higher Education of Ensenada (CICESE), Baja California, Mexico. He is currently a full-time adjunct professor at the ITM, where he teaches programming, logic, and optics-related courses. His research interests focus on the modeling, simulation, and experimental validation of fiber optic devices, including long-period fiber gratings, photonic crystal fibers, microring resonators, and terahertz waveguides, with applications in optical sensing, communications, and quantum optics. He has co-authored more than 18 publications, including peer-reviewed journal articles and conference papers. Recent works address topics such as optical parametric amplification in microstructured fibers, machine learning approaches for the inverse design of photonic devices, deep learning-based optical sensing, and the development of porous-core photonic crystal fibers for terahertz applications. He supervises research projects on photonics, sensing, and terahertz technologies.
