The creation of large Human Brain Mapping Projects opened the opportunity to explore in vivo brain mechanisms like never before. In this talk, I will present how we have used multimodal neuroimaging datasets, and statistical and machine learning, to find ways to deal with the unfeasibility of some problems present in Electrophysiology across species, to test competing biophysical theories of how the waves of activity are generated in the brain, to create clinically relevant biomarkers of epileptic foci, and to characterize chronic pain-related alterations in brain anatomy and function.

Dr. Valdes-Hernandez Nuclear Physics, and completed his Ph.D. in Physics at the University of Havana in 2016. He specializes in Neuroimaging, specifically, in the disciplines of Neuroinformatics, Medical Image Analysis, Biostatistics, Computational Neuroanatomy, Computational Neurosciences (e.g., modeling of brain dynamics), and the Biophysical Modelling of the Brain (specifically modeling the underlying biophysical mechanisms and signal formation of EEG/MEG and BOLD fMRI). He has worked with large multimodal neuroimaging databases of both clinical and preclinical (rats and monkeys) studies. Using these databases, he has applied statistical learning to test several biophysical theories of the brain. He has more than 16 years of experience performing MRI and EEG experiments. This includes the man in both human and rat studies, as well as the acquisition and analysis of simultaneous and standalone EEG and fMRI data. With a mindset on the betterment of the health and quality of life of society, he has dealt with a variety of pathological populations, covering a wide range of ages (e.g., children with Epilepsy and older adults with and without chronic pain).
