Goñi to present at Mediterranean School of Complex Networks
On Sept. 6, Goñi, assistant professor of industrial engineering, will lead a seminar on Advances in Network Neuroscience, and give a talk on "On the quest of fingerprints in brain networks: identifiability and beyond".
Abstract
In the 17th century, physician Marcello Malpighi observed the existence of patterns of ridges and sweat glands on fingertips. This was a major breakthrough and originated a long and continuing quest for ways to uniquely identify individuals based on fingerprints. In the modern era, the concept of fingerprinting has expanded to other sources of data, such us voice recognition and retinal scans. It is only in the last few years that technologies and methodologies have achieved high-quality data for individual human brain imaging, and the subsequent estimation of structural and functional connectivity. In this context, the next challenge for human identifiability is posed on brain data, particularly on brain networks, both structural and functional.
Goñi will present how the individual fingerprint of a connectome (as represented by a network) can be maximized from a reconstruction procedure based on group-wise decomposition in a finite number of brain connectivity modes. By using data from the Human Connectome Project, Goñi will introduce different extensions of this work, including subject identifiability, heritability analysis of brain networks, as well as identifiability when assessing inter-task brain functional networks. Lastly, he will discuss results of this framework for inter-scan identifiability based on a second dataset acquired at Purdue University.
Second-year PhD student Duy Duong-Tran will also attend the School. On Sept. 4, he will give a three-minute OneShot Talk titled "A morphospace framework to assess functional networks' flexibility".
About the School: In the last decade, network theory has been revealed to be a perfect instrument to model the structure of complex systems and the dynamical process they are involved into. The wide variety of applications to social sciences, technological networks, biology, transportation and economic, to cite just only some of them, showed that network theory is suitable to provide new insights into many problems. The 5th Mediterranean School of Complex Networks will take place in Salina, Sicily from Sept. 1-8, 2018.
