I am a postdoctoral researcher at the University of Murcia (UMU), where I work under the guidance of Prof. Antonio Skarmeta. My research interests lie at the intersection of communication system analysis, design and network optimization, with a strong emphasis on energy efficiency, reliability, and practical deployment evaluations. Before joining UMU, I completed my Ph.D. in Telematics Engineering at Universidad Carlos III de Madrid (UC3M), where I was advised by Prof. Pablo Serrano. Throughout my academic journey, I have actively bridged research and real-world impact, visiting and collaborating with institutions such as IMDEA Networks, NEC Laboratories Europe, and Fraunhofer FHR. Additionally, I have worked on several EU-funded research projects addressing a range of topics including network orchestration, energy-efficient architectures, and intelligent automation for 5G and 6G systems.
