      This talk will discuss the problem of finding effective laws that the govern the overall evolution of free boundaries propagating in a heterogeneous media.  This is motivated by a number of phenomena in mechanics and materials physics including phase boundaries, peeling of adhesive tape, dislocations, fracture and wetting fronts....

      Thermoacoustic (TAT) and Photoacoustic Tomography (PAT) are examples of multiwave imaging methods allowing to combine the high imaging contrast of one wave (an electromagnetic or a photoacoustic one) with the high resolution of ultrasound. We present recent results obtained in collaboration with Gunther Uhlmann, Jianliang Qian and Hongkai...

    In this talk, which will be will be aimed at a general math audience, we shall overview an approach to analyze coupled slow-fast dynamics via Young measures, namely, via probability measure valued maps. The framework is ordinary differential equations, possibly controlled. We shall address the modeling issue, motivating examples, the mathematical...

    What could be simpler than to study sums and products of integers? Well maybe it is not so simple since there is a major unsolved problem: for arbitrarily large numbers N, can there be sets of N positive integers where both the number of pairwise sums and pairwise product is less than N^{3/2}? No one knows. This talk is directed at another...

    Mathematical modeling, analysis and numerical simulation, combined with imaging and experimental validation, provide a powerful tool for studying various aspects of cardiovascular treatment and diagnosis. This talk will address two examples where such a synergy led to novel results. The first example concerns a mathematical study of fluid-...

    In this talk, I will be discussing various funding and other opportunities for mathematical and statistical sciences at NSF. New programs in computational and data-enabled sciences will be discussed. Also,this is an opportunity to hear feedback from the community regarding future needs.
