Hi, I'm Jose Carlos Sanchez Valera
Telecommunications Engineer and AI PhD candidate
Curious and collaborative, I am a Telecommunications Engineer and AI PhD candidate at the
University of Granada. My research lies at the intersection of deep learning and signal
processing, focusing on voice anti-spoofing and audio security.
Outside of research, I am passionate about sports and fitness. Active living helps me
maintain a healthy work-life balance, bringing energy and discipline.
