Professor Markos Katsoulakis received a CDI-Type II grant from the National Science Foundation for $1,600,000. The participating institutions are UMass Amherst, University of Delaware, and University of Tennessee. The title of the grant is Collaborative Research CDI-Type II: Hierarchical Stochastic Algorithms for Materials Engineering. That the competition for these grants was extremely keen can be seen from the fact that throughout all the science and engineering divisions of NSF only seven such grants were funded. A new NSF initiative, CDI is an acronym for Cyber-Enabled Discovery and Innovation.

The title of his talks at both the conference and the workshop was Chow, Moduli-Theoretic, and Tropical Quotients of Grassmannians. His paper entitled Elimination Theory for Tropical Varieties, written jointly with Bernd Sturmfels, was published in Mathematical Research Letters, volume 15, number 3 (2008).
During the period June 16ñ27, 2008 Professor Emeritus Floyd Williams presented a Graduate Workshop at the Mathematical Sciences Research Institute (MSRI) at the University of California, Berkeley. The workshop, entitled A Window into Zeta and Modular Physics, was attended by 33 gifted graduate students. It featured two daily lectures and a speakerís seminar in which four invited speakers gave advanced lectures on their current research. The workshop also featured special lectures by graduate students including Floydís two graduate students, Shabnam Beheshti and Jennie DíAmbroise. Shabnamís lecture was entitled How a Soliton Illuminates a Black Hole, and Jennieís lecture was entitled On Relating d-Dimensional Cosmology to Bose-Einstein Condensates. Floydís lecture at the speakerís seminar was entitled Quantum Corrections to Black Hole Entropy Via a Deformation of the Patterson-Selberg Zeta Function. Given the apparent success of the workshop, MSRI invited Floyd to edit a book entitled A Window into Zeta and Modular Physics. To be published by MSRI, the book will feature the daily lectures, the lectures given at the speakerís seminar, and the four special lectures by graduate students.
