Title: Applying Modern Geometry in Neuroimaging Research

Presenter:Yalin Wang

Time:2017 June 13 1500(Tuesday)

Place: Lecture Hall 406

 

AbstractWe live in a 3D environment. Many daily computing tasks, such as searching a route viaGoogle Maps or playing a game with Microsoft's Kinect, all involve geometry processing. Geometry knowledge has been used in almost every computer science field, such as pathplanning in robotics, sensory network, manifold learning, etc.Biologically, a mapping from retina to brain cortical surface has been proved to be conformal on animal models but remains an open problem for human brains.

 

At ASU, my students and I are focusing on developing modern geometry-based software to address challenging neuroimaging research problems. Rooted in the Riemann geometry, conformal geometry and hyperbolic geometry, a series of algorithms, including multivariate tensor-based morphometry, surface conformal parameterization, volumetric Laplace-Beltrami operator, hyperbolic Wasserstein distance, have been developed and applied to human brain imaging research problems relating to Alzheimer’s disease, child development, and human retinotopic mapping studies. In this talk, I will present our recent work and some exciting geometry theories involved.

 

Bio: Yalin Wang received his bachelor’s and master’s degrees fromTsinghua University, and his PhD from University of Washington. During his postdoc period, he has been working with some world-class mathematicians, including the fields medalist, Prof. Shing-Tung Yau and the member of National Academy of Engineering, Prof. Tony F. Chan. Currently, he is an associate professor with tenure in School of Computing,Informatics, and Decision Systems Engineering (CIDSE) at Arizona State University (ASU), where he directs theresearch laboratory of Geometry Systems Laboratory (GSLhttp://gsl.lab.asu.edu). His research is in the areas of brain imaging, computer vision and statistical pattern recognition. His work has been funded by a total of 7 grants from the National ScienceFoundation (NSF), National Institutes of Health (NIH) and Arizona Alzheimer’s consortium. He has published a text book and over 200 papers in a variety of technical conferences and journals.He received the “2016 Best Junior Faculty Researcher Award” from ASU CIDSE.
