Abstract: Broadway in Chicago President and CEO Lou Raizin will visit Northwestern to convene people from across the university to learn more about his vision for the Cultural Stadium in Chicago: where he imagines the possibility of linking art and engineering with a kinetic or robotics-related sculpture to inspire wonder in the Loop.
The Cultural Stadium reimagines downtown Chicago as a vibrant, inclusive arena of cultural life—where every street, bridge, and building becomes a stage. Inspired by the scale and spirit of a stadium, the concept brings culture to the forefront through art, live performances, and creative community spaces. With projects like the LaSalle Street transformation, it blends affordable housing, artist studios, and public exhibitions to make culture accessible and alive. This vision calls for structural shifts—zoning, funding, and public-private collaboration—to turn downtown into a bold, living showcase of Chicago’s creativity and diversity. A place where culture isn’t background—it's center stage.
Co-sponsored by McCormick School of Engineering, Arts + Engagement Initiative and Center for Robotics and Biosystems
Bio: Lou Raizin has over 40 years of experience in the entertainment industry. As a founder and the prime mover behind Broadway In Chicago, a joint theatrical venture formed in 2000, his leadership propelled the transformation of Chicago from a short-term stop on “the road” to the third most important city in the world for theater. Encompassing the five premiere theater stages in the city, Broadway In Chicago has presented over 400 productions, bringing an economic impact of over $750 million annually to the City of Chicago and State of Illinois and supporting more than 9,200 local jobs.
Raizin’s focus on economic development, tourism and the support of culture in our City has led to the creation and continued sponsorship of the annual League of Chicago Theatre’s Emerging Theatre Award and the Illinois High School Musical Theatre Awards. Mr. Raizin has been named one of Chicago Magazine’s 100 Most Powerful Chicagoans and is a tireless advocate for Chicago as a cultural destination, having served as the Board Chair of the Chicago Loop Alliance leading the organization in the creation of Pop Up Art Loop, comprised of over 14 galleries and as well as the installation of a number of major public art projects in the city including the lighting and music display along State Street.
Outside of Broadway In Chicago, Raizin’s focus is often at the intersection of arts, culture and economic development to create jobs in the city. He had long served as Treasurer for Choose Chicago and on the Executive Committee of Choose Chicago and is a Board Member of the Magnificent Mile Association. He previously chaired the Chicago Loop Alliance and the State Street Commission for multiple terms, served as a member of the Economics Club as well as serving as a director of a number of other civic and not-for-profit organizations. He founded and chaired the Board of LUMA8 (Light Up My Arts), the entity that produces the Arts In The Dark Parade and the River Walk Lantern Festival. Raizin also served as the catalyst for both the $12M permanent light art installation on the back wall of the Merchandise Mart and a digital platform for tourism.

ABSTRACT
My research group explores high-resolution optical techniques to investigate elastic wave and heat transport phenomena in condensed matter. In the first half of my talk, I will describe our work on thermal conductivity imaging near single grain boundaries (GBs) in thermoelectric materials. GBs are critical microstructural components that control the performance of thermoelectric materials by reducing the bulk thermal conductivity through the scattering of lattice waves. To date, most GB-thermal conductivity studies have primarily focused on grain size as a fundamental structural property that is important for reducing thermal conductivity. However, it is unclear if the right strategy for optimizing the thermoelectric performance is suppressing the thermal conductivity using small (or nanosized) grains or proliferating thermally resistive GBs. Addressing this fundamental question will be critical to developing next-generation thermoelectric generators for deep space exploration and commercial solid-state refrigerators for mobile phone and electric vehicle applications. In our work, we examine the impact of the GB morphology (e.g., misorientation angle, roughness of the GB plane, nanotwinning, porosity, etc.) on the local thermal conductivity suppression near individual GBs. Our measurements show that the “all GBs are the same” picture adopted in thermal conductivity homogenization modeling is not accurate. Alternatively, each GB is best described as a unique complexion that differs from the surrounding bulk phase. The GB complexion may be controlled by adjusting the thermodynamic parameters of processing methods, leading to complexion transitions similar to those in bulk materials, which can result in drastic changes in bulk transport properties and enhance thermoelectric performance. In the last half of my talk, I will present a dynamic optical coherence elastography (OCE) technique that relies on optical measurement of bulk shear wave propagation for the characterization and mapping of shear viscoelastic properties. My group has adapted the method for viscoelastic characterization of wastewater biofilm membranes and beads. These materials are heterogeneous and may be layered, leading to guided or interfacial elastic waves. I will discuss how we harnessed these wave modes to probe spatial variations in viscoelastic properties, track changes in pH and crosslinking time, and address the influence of stretch-dependent properties.

Abstract:
In this lecture, mass lumped, rate-type C continuous finite element models of arbitrarily higher order using shear deformable beam, plate, and shell elements are discussed. Higher-order elements provide true curvature, improved performance in bending and buckling, and avoid hourglass modes and numerical locking without ad hoc treatments. Historically, first-order shear deformation finite elements have been predominant in explicit finite element codes because of difficulties achieving robust and reliable mass-lumping. We spatially discretize using a standard weak-form 0 Galerkin finite element approximation and optimal C Lagrange shape functions of arbitrarily higher order and integrate throughout time using a central-difference method and a lumped mass matrix. Several numerical examples of nonlinear finite deformation demonstrating the accuracy and utility of the lumped-mass elements developed are presented.

Abstract:
The functioning of Li metal-solid state batteries (LMSSB) requires that interfacial contact between the Li metal anode and the solid electrolyte (SE) be maintained during cycling. A reduction in contact area during Li stripping will increase the local current density during subsequent Li plating, fostering dendrite nucleation. The contact area is influenced by the rate of Li transport within the anode towards the interface. Relevant transport mechanisms include diffusion and creep, with faster rates of these processes resulting in improved performance. Given the importance of these transport modes, predicting them as a function of the anode’s microstructure, stress state, and temperature will be helpful in the design of LMSSB. Here, the rates of diffusion and creep in Li are predicted using atomic scale simulations. A primary goal is to understand if and how Li microstructure impacts the performance of LMSSB. First, molecular dynamics is used to estimate the rate of Li diffusion along dislocations and in grain boundary triple junctions. By combining this data with that from a prior study of grain boundary diffusion, the dominant diffusion mechanisms and overall rates of self-diffusion in Li polycrystals are predicted as a function of grain size, grain shape, dislocation density, and temperature. A 1D continuum model for interfacial contact is parameterized using the computed diffusion data. The model predicts that high dislocation densities (~10 12 /cm 2 ) and/or small grain sizes (~10 m) enable achieving battery performance targets. Secondly, the dominant creep deformation mechanisms are predicted as a function of applied stress, grain size, and temperature. Grain boundary sliding and coble creep are observed to be the primary mechanisms for micron-sized grains. Finally, a kinetic lattice Monte Carlo model is developed to monitor the dynamics of Li voids as a function of interfacial thermodynamics and the presenceof grain boundaries.
