Summary of the Workshop:
The Workshop took place at the sixth floor seminar room ACES 6.304 of the Institute for Computational Engineering and Science on the campus of the University of Texas at Austin.
It consisted of 28 plenary lectures delivered by well-known specialists in central areas of non linear science from participating universities in Portugal, Carnegie Mellon University, Rice University. University of Houston, Texas A&M University, and the University of Texas at Austin. These talks included multiscale modeling of complex systems, metamodels for oil reservoir parameter estimation, derivative-free optimization of expensive models, seismic inverse scattering, topology optimization of structure and materials, cancerigenous cells, multiphase problems and related topics in computational science.
Lectures were heavily attended (on the order of fifty to sixty participants), and they were very lively with scientific exchanges during and after the lectures.
Assistant professors that will spend the spring semester at UT Austin made contact with the research groups of their interest and established contact with their mentors (Luis Caffarelli, Misha Vishik and Mary Wheeler).
Scientific exchanges were initiated (F. Chalub and I. Gamba), and detailed mathematical consultation on problems in biomathematics and medical imaging occurred between Isabel Figueiredo from the University of Coimbra and Omar Ghattas, Chandrajit Bajaj, Richard Tsai and Bjorn Engquist from Texas. Tentative exchanges were discussed, including a visits to UT to start collaboration with Luis Caffarelli, and the possibility for Caffarelli and Gamba to spend a month in Lisbon on 2009.
There was also the opportunity that students and faculty from the four Portuguese universities will attend the course that P-L Lions (College de France) will deliver in Austin this winter.
Among the participants were Irene Fonseca, David Kinderlehrer and Robert Pego from the CMU program, and the opportunity was used to discuss ways to improve the programs and enhance cooperation between the two CoLab initiatives.
