Ricardo Bruña

Soy ingeniero de telecomunicaciones por la Universidad de Valladolid y doctor en ingeniería biomédica por la Universidad Politécnica de Madrid. Trabajo en el Laboratorio de Neurociencia Cognitiva y Computacional desde 2011, y me he dedicado, principalmente, al desarrollo de métodos de limpieza y análisis de señal cerebral para EEG y MEG, y en el estudio de algoritmos de reconstrucción de fuentes.

Durante estos años he trabajado en desarrollo de métodos puros, así como en su aplicación a envejecimiento, temblor y consumo de alcohol. También he participado y participo en la implementación de la herramienta de cálculo de conectividad HERMES.
