Speaker: Dr. Anand A. Joshi, Postdoctoral Associate, Signal and Image Processing Institute, USC
Talk Title: âGeometric Methods for Brain Image Registration and Signal Analysisâ
Abstract: My talk will focus on applications of techniques from Riemannian geometry to signal and image processing, with the emphasis on human brain imaging. Studies of anatomical changes in the brain over time or of differences between populations are often performed to understand changes in disease and development. Such studies require that the imaging data first be registered to a common coordinate system. Registration and analysis of neuroimaging data presents a challenging problem due to the complex folding patterns in the human brain. Specifically, the anatomical and functional brain data is often modeled as a highly convoluted 2D curved image. Since it is non-flat, the non-Euclidean geometry of this data needs to be accounted for performing registration and subsequent signal processing. Techniques from differential geometry offer a powerful set of tools to deal with the convoluted nature of the cortex. I will present a method based on p-harmonic mapping when performing cortical surface parameterization as well as surface and volumetric registration techniques for inter-subject alignment of brains. Furthermore, I will present techniques for filtering, pattern classification and spectral analysis that use the heat kernel and the eigenspectrum of the Laplace-Beltrami operator that forms a basis for analysis on the cortical surface. I will conclude the talk with a description of recent work on the use of brain imaging data to elucidate structural and functional connectivity in the human brain.
Biography: Bio: Dr. Anand Joshi received his B.E. degree in Electronics from Shivaji University and MTech in electrical engineering from Indian Institute of Technology, Kanpur. He also worked for Siemens and later for Sasken. Dr. Joshi received his Ph.D degree in electrical engineering from USC in 2008 followed by postdoctoral training in the Laboratory of Neuro Imaging at UCLA. Dr. Joshi's research interests lie in the area of brain imaging, geometric methods and brain connectivity.

Academic Spotlight: Professor Willner
Tue, Nov 01, 2011 @ 06:00 PM - 07:00 PM

Student Activity
What: Academic Spotlight Series talk by Professor Willner
Where: SLH 102
Date: 11/1, 6pm
Join us for one of our Academic Spotlight Series talks with Professor Willner.
The topic of this talk is: "Optical Communication Systems: Innovations (and Their Needs) Abound"
ABSTRACT: The optical communications revolution continues, as the 10-year-horizon capacity needs are expected to grow by 2-3 orders-of-magnitude and the "Terabit/s Ethernet" might be reached. Importantly, optics might be a powerful enabler for additional transformative functions, including:
(a) stable and reconfigurable networking,
(b) high-speed signal processing, and
(c) low-power interconnections.
It is quite possible that optics will follow trends of the RF world, such that robustness, spectral-efficiency and functionality will increase dramatically. Some challenges in achieving this vision include:
(i) high-bandwidth and tunable technologies,
(ii) linear and nonlinear elements, and
(iii) maintenance of signal integrity.

There will of course be free food!Location: John Stauffer Science Lecture Hall (SLH) - 102
