Chialvo Awarded Fulbright

September 27, 2005

Dante R. Chialvo, M.D., research associate professor of physiology at the Feinberg School of Medicine, has been awarded a Fulbright Scholar grant to lecture and conduct research at the University of Cordoba, Argentina. He will work with the faculty of mathematics, astronomy and physics in the department of physics.

Recipients of Fulbright Scholar awards are selected on the basis of academic achievement and for demonstrating extraordinary leadership potential in their fields.

Chialvo's research is dedicated to understanding natural phenomena from the point of view of nonlinear dynamics of complex systems. His work covers a wide range of topics, including the mathematical modeling of cardiac arrhythmias; the study of molecular motors as stochastic ratchets; neural coding; and self-organization and collective phenomena in ant colonies, the brain and human communities.

In their research of the human brain, Chialvo and an international group of colleagues have shown that tens of thousands of discrete brain regions form a network that has the same qualitative features as other complex networks, such as the Internet and social and metabolic networks. Two fundamental features in each of these are the "small world" property whereby few jumps are necessary for connecting any two nodes, and in-homogeneity, or selected "super-connected" nodes which act as hubs providing fast transmission of information.

Chialvo has visited at major institutions worldwide, including in Spain, Argentina and Denmark (the Niels Bohr Institute) and in the United States (University of California at Los Angeles, Rockefeller University and Cornell University).
