MICDE Seminar: George Biros
George Biros is the W. A. “Tex” Moncrief Chair in Simulation-Based Engineering Sciences in the Institute for Computational Engineering and Sciences and has Full Professor appointments with the departments of Mechanical Engineering and Computer Science at the University of Texas at Austin.
From 2008 to 2011, he was an Associate Professor in the School of Computational Science and Engineering at Georgia Tech and The Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University. From 2003 to 2008, he was an Assistant professor in Mechanical Engineering and Applied Mechanics, Bioengineering and Computer and Information Science at the University of Pennsylvania.
He received his BS in Mechanical Engineering from Aristotle University Greece (1995), his MS in Biomedical Engineering from Carnegie Mellon (1996), and his PhD in Computational Science and Engineering also from Carnegie Mellon University (2000). He was a postdoctoral associate at the Courant Institute of Mathematical Sciences from 2000 to 2003.
Dr. Biros has research interests in Computational Science and Engineering. In particular, he works on numerical methods for integral and differential equations, inverse problems, statistical inference, and parallel algorithms. Applications include blood rheology, soft tissue mechanics, medical image analysis, electrophysiology, and forward and inverse scattering problems. Biros was among a team of researchers that won the IEEE/ACM SC03 and SC10 Gordon Bell Awards for special Achievement. His work has been further recognized for its importance with the IEEE/ACM SC03 best student paper (advisor), the IEEE/ACM SC02 best technical paper, and the IEEE/ACM SC07 best student paper finalist (advisor). In 2005, he received an Early Career Young Investigator Award from the U.S. Department of Energy. He serves as an Associate Editor for the SIAM Journal on Scientific Computing since January 2007 and as an Associate Editor for the ACM Transactions of Mathematical Software since 2011.
Scalable Algorithms for the Evaluation of Volume Potentials
4 p.m., Tuesday, March 11, 2014
Room 1360, East Hall, 530 Church St.
Dr. Biros will consider the problem of evaluating volume potentials in three dimensions. The evaluation of volume potentials is a well understood problem. Such potentials can be used for solving boundary value problems, for example the Laplace, Stokes and Helmholtz problems. Despite the significance of such methods, there exist no scalable efficient implementations and as a result their use from non-experts is somewhat limited.
Dr. Biros will discuss the formulation, numerical challenges and scalability of algorithms for volume potentials and present a new open-source library for such problems. He will compare their performance to other state-of-the art codes and conclude with an example from computational fluid mechanics.
This is joint work with Dhairya Malhotra and Bryan Quaife.
