Francisco J. Fraga received a Bachelor's and Master's degree in Electronic Engineering from the Polytechnic School of the University of São Paulo (EPUSP), Brazil, in 1987 and 1991, respectively. He obtained the title of Doctor in Electrical Engineering and Computer Science from the Instituto Tecnológico de Aeronáutica (ITA, 1998). From 2000-2004 he worked as an Assistant Professor at the Instituto Nacional de Telecomunicações (INATEL). In 2005 he was Senior Researcher at the Integrated Systems Laboratory at the University of São Paulo, working in the AAC Audio Encoder / Decoder in the Brazilian Digital TV System (SBTVD) project. Since 2006 he has been with Federal University of ABC (UFABC), Brazil, currently as Full Professor. From 2012 to 2013 he was Visiting Scholar at the University of Quebec (Montreal, Canada) and from 2019 to 2020 he was Visiting Researcher at the Sapienza University of Rome (Italy). His research interests include anything related to biosignal processing/classification, and his current line of research is primarily focused on EEG processing and classification for brain disorders and the brain-computer interface.

Alzheimer's disease (AD) is the most common neurodegenerative disease among the elderly, with progressive decline in cognitive function, significantly affecting quality of life. The prevalence and emotional and financial burden of AD on patients, their families and society are predicted to grow significantly in the near future due to the global increase in life expectancy at birth. Thus, …
The main cause of acquired brain injury (ABI), according to the literature, is traumatic brain injury (TBI). TBI is non-degenerative and non-congenital damage caused by external mechanical force. A permanent or temporary impairment of cognitive, physical and psychosocial functions is expected, with a decrease or alteration of the state of consciousness. The most frequent causes of TBI are…
While the overall growth in life expectancy is extremely positive, the aging population has been followed around the world, for it also leads to some disturbing consequences, such as the increasing prevalence of neurodegenerative diseases. Among those, by far the one with highest incidence is Alzheimer's Disease (AD), which early detection is a pressing need, since it allows to start a tr…
Recent experimental evidence has suggested a neuromodulatory deficit in Alzheimer's Disease (AD). In this paper, we present a new electroencephalogram (EEG) based metric to quantitatively characterize neuromodulatory activity. More specifically, the short-term EEG amplitude modulation rate-of-change (i.e., modulation frequency) is computed for five EEG subband signals. To test the perform…
Alzheimer's disease (AD), characterized by the presence of neurofibrillary tangles and senile plaques in the brain, is a dementia affecting great part of the elderly population, with an incidence that has increased significantly in the last decades. Thus, early detection of AD becomes a public health issue, as it allows starting treatment able to significantly delay the disease progressio…
According to the United Nations, the world elderly population is growing at its fastest rate ever. It is expected that by 2050, more than 2 billion people will be aged over 60, with 70% of them living in low or middle-income countries. For many individuals, ageing causes cognitive decline and limited functional capacity, thus placing a burden on the healthcare system. A clear example of t…
