Bio

Javier Villanueva‑Valle is a researcher in Behavioral Neuroscience and holds a PhD in Psychology from UNAM. His work inhabits the intersection between psychopathology, human ethology, and data science, with the purpose of listening to what manifests between the lines in human emotional experience.

During more than a decade at the National Institute of Psychiatry Ramón de la Fuente Muñiz, he studied the dissonance between declared emotion and non-verbal expression in patients with Borderline Personality Disorder, coining the concept of expressive paradox. His methodological approach integrates computational voice analysis (PRAAT) and facial expression analysis (FaceReader), articulated with Python for data synchronization, processing, and interpretation.

His trajectory defends a science that does not shy away from ambiguity and a clinical practice in which measurement assists—without eclipsing—the irreducible complexity of the human being.

He currently serves as an expert psychologist in high-impact contexts, applying his knowledge of behavior and emotion to the technical clarification of complex cases with methodological rigor and ethical sensitivity.
