Principal Investigator

Luca Faes

I am a biomedical engineer working in the fields of biomedical signal processing and computational neuroscience and physiology. During both my training and my professional career I have always had a keen interest in the theoretical and methodological aspects of signal processing. Following these interests, my research is directed to the development of techniques for multivariate time series analysis, with emphasis on the use of Information Theory for the characterization of complex network systems. In the BIT lab at Unipa, we apply these techniques to time series derived from multiple biosignals tracking the dynamic activity of the brain, cardiovascular and respiratory systems, and we investigate how the underlying physiological networks evolve across several physiological states and pathological conditions.

Researchers

Riccardo Pernice

I am an Assistant Professor in Biomedical Engineering working in the fields of biomedical signal processing and time series analysis. During my professional career, I have coauthored 44 journal papers and more than 105 international conference papers, attending 13 national/international conferences. My activity has been mainly focused on the acquisition of electrocardiographic and photoplethysmographic signals and their processing, with particular regard to heart rate variability analyses. Other research activities currently carried out encompass electronics and photonics for biomedical applications, time series analysis, network physiology, and interactions between physiological systems (e.g. cardiorespiratory, cardiovascular and brain-heart)

Doctoral Students

Laura Sparacino

I am a PhD student in Information and Communication Technologies (cycle XXXVII). My research activity is focused on the development of novel measures of clinical and general interest for the assessment of bivariate and/or complex high-order interactions among multiple signals originating from different body districts. The study of the collective behavior of these biomedical signals would provide a multi-modal description of the human body as an integrated network, where complex physiological systems dynamically interact and integrate their functions to generate a variety of physiologic states at the organism level. Practically, the main idea behind the framework consists in defining these measures in the information-theoretic domain, exploiting their well-known computation based on linear multivariate parametric models, and in their expansion in the frequency domain. This allows the investigation of the rich oscillatory content of individual physiological signals and the retrieval of amounts of information shared by the observed processes within specific frequency bands.

Chiara Barà

I am a PhD student in Information and Communication Technologies (cycle XXXVIII). The research activity I carry out within the BIT lab is aimed at the development and application of methods and algorithms for the study of pathophysiological states starting from physiological time series. My activity is mainly focused on physiological signal processing, the investigation of cardiovascular and brain-heart interactions, and the study of these processes using model-free approaches to estimate information theory measures.
