### Recent Advances in Applied and Computational Mathematics: A Workshop in Memory of Professor Peter Smereka

Peter Smereka was a leading applied mathematician who had tremendous impact on an unusually wide variety of topics in applied and computational mathematics. His work in multiphase flow and interfacial motion (e.g. the level set method) has been particularly influential and is considered among the classics of the field. Just as well known are his papers in material science, where he made many original contributions to the modeling and simulation of faceted crystal growth, epitaxial growth, and to the kinetic…

### 2018 Summer School on Random Matrices

The summer school is the second installation of the highly successful 2016 Summer School on Random Matrices at the same venue (the University of Michigan) and by the same organizers (Baik and Nadakuditi). We plan to establish the summer school as a continuing bi-annual event. Random matrix theory is a study of the eigenvalues and eigenvectors of (typically large) random matrices. See the Event Website for More Details

### Women in Mathematics of Materials (WIMM) Workshop

Materials Science is an interdisciplinary field that focuses on the discovery and design of new materials. Mathematics plays a fundamental role when developing models that describe the processing, structure, and properties of materials. This is a domain that encompasses many fields that include Continuum Mechanics, Partial Differential Equations, Computational Solid Mechanics , etc. These areas have evolved synergistically over the centuries, one field informing the other and together creating a solid foundation for resolving important issues in elasticity of materials,…

### Alexander Ziwet Lectures presents: Gunther Uhlmann

Gunther Uhlmann, Walker Family Endowed Professor of Mathematics, University of Washington Colloquium. Harry Potter's Cloak via Transformation Optics, Room 1360 East Hall @ 5:00 PM Abstract: Can we make objects invisible? This has been a subject of human fascination for millennia in Greek mythology, movies, science fiction, etc. including the legend of Perseus versus Medusa and the more recent Star Trek and Harry Potter. In the last decade or so there have been several scientific proposals to achieve invisibility. We…

Interacting excitatory and inhibitory neuronal populations often generate oscillations in electrical fields in the brain. I will briefly review this mechanism and the reasons to believe that it is important in brain function. Most of the talk will be focused on the effects of recurrent excitation, i.e., of the neurons of a local network in the brain exciting each other. Recurrent excitation can sustain activity in a network that would otherwise be quiescent; this is believed to be the basis…

### Joseph Paulsen: Better living through frustration or: Shaping liquid surfaces with thin elastic sheets

Gauss's Theorema Egregium is the source of many annoyances: flat bandages don't stick as well to curved knuckles or elbows, maps of the earth exaggerate areas near the poles, and automotive metal must be pounded to make a doubly-curved fender. We are investigating such "geometric frustration" in a class of extremely bendable materials that are nonetheless hard to stretch. I will discuss recent experiments in three settings, where we wrap, poke, and squeeze ultrathin polymer films on liquid surfaces. Surprisingly,…

Medical imaging benefits from advances in constructive approximation, orthogonal polynomials, Fourier and numerical analysis, statistics and other branches of mathematics. At the same time, the needs of medical diagnostic technology pose new mathematical challenges. This talk surveys a few problems, some of them related to approximation theory, that have appeared in my collaboration with specialists studying some pathologies of the human eye, in particular, of the cornea, such as: - reconstruction of the shape of the cornea from the data…

Many fundamental phenomena in eukaryotic cells - nuclear migration, spindle positioning, chromosome segregation - involve the interaction of (often transitory) cellular structures with boundaries and fluids. Understanding the consequences of these interactions require specialized numerical methods for their large-scale simulation, as well as mathematical modeling and analysis. In this context, I will discuss the recent interactions of mathematical modeling and large-scale, detailed simulations with experimental measurements of activity-driven biomechanical processes within the cell.

### Eric Keaveny: Linking the micro- and macro-scales in populations of swimming cells

Swimming cells and microorganisms are as diverse in their collective dynamics as they are in their individual shapes and swimming mechanisms. They are able to propel themselves through simple viscous fluids, as well as through more complex environments where they must interact with other microscopic structures. In this talk, I will describe recent simulations that explore the connection between dynamics at the scale of the cell with that of the population in the case where the cells are sperm. In…
