He is currently engaged in pioneering research on next-generation advanced neural interfaces at Jia Liu's Lab. His primary area of focus is brain-machine interfaces, with a special emphasis on harmonizing artificial and natural intelligence. His efforts are directed towards enhancing the long-term stability and efficiency of these biological interfaces, integrating techniques from signal processing, artificial intelligence, and bioelectronics. Currently, Arnau is developing novel neural models tailored for processing extensive brain recordings data.
