Umberto Melia

UmbertoMelia_B2SLab Welcome to my site. My name is Umberto Melia. I was a PhD student at the B2SLab. This lab belongs to the Biomedical Engineering Research Center (CREB) at the Universitat Politècnica de Catalunya (UPC), in the city of Barcelona. I am from Italy, but thanks to the ERASMUS program, I could make my master thesis in Barcelona where I decided to start my PhD.

My Research Activities at B2SLab

My history at B2Slab began with the development of the final project of my Master in Biomedical Engineering. In this work I applied Time-Frequency representation onto DNA sequences converted in numerical sequences. After that, I worked as a junior researcher for the development of an algorithm that automatically evaluates the quality of spirometry curves. Now I am almost finishing my PhD. My activities as a PhD students dealt with the application of linear and nonlinear techniques to EEG and RR signals for the characterization and prediction of the responses to nociceptive stimuli in healthy subjects or during sedation and for the characterization of drowsiness levels.
