MS and Ph.D. advisor

I advise students from engineering, physics, computer science and equivalent backgrounds in the Electrical Engineering Program of the Escola Politécnica da USP (http://www.pcs.usp.br/~posgrad-eletrica/). These students usually do research on the mathematical modelling of neurons and their networks, synapses, muscles and the complex interactions of all these elements together. One of the goals is to increase knowledge related to motor control at different levels of organization.

I also advise students from biomedical sciences backgrounds in the campus-wide Neurosciences Program (http://www.ip.usp.br/portal/index.php?option=com_content&view=article&id=949%3Aapresentacao-do-programa-de-pos-graduacao-em-neurociencias-e-comportamento&catid=252&Itemid=114&lang=pt). These students do experimental work dealing with human motor control and human spinal cord.

Specific Research Interests

 Spinal cord neurophysiology studied by means of the analysis of  postural and reflex dynamics. Analysis of the electrical activity of muscles, nerves and the brain for research and clinical diagnosis. Mathematical modeling and simulation of neurons, synapses and neuronal networks of the spinal cord.

Some Activities at the University of Sao Paulo

 Teaching undergraduate and graduate courses, e.g.,  Signals and Systems I and II, Fundamentals  of  Neuroscience, Spinal Cord Neurophysiology, Neurophysiology of Motor Control, Digital Signal Processing, Biological Signal Processing. Advising undergraduate and graduate students (from the biomedical and the hard sciences) on human neurophysiology and on neuronal modeling and simulation. Coordinating many of the activities of the lab.

Research Experience

H-reflex, presynaptic and reciprocal inhibition in humans, bilateral reflexes; postural control; evoked brain potentials; human electromyography; digital signal  processing and pattern recognition applied to neuroelectric signals; modeling and simulation of neurons and neuronal networks;  biomedical instrumentation; crayfish inhibitory synapse and stretch receptor dynamics.
