SUMMARY:Physics Colloquium: Shashank Shekhar
DESCRIPTION:Title: Self-assembly Across Scales: From Cytoskeletal Dynamics to Evolution of Multicellularity \nAbstract: Self-assembly is a fundamental process that drives organization and function across biological systems\, from molecular complexes to multicellular structures. In this talk\, I will present our recent research on the role of self-assembly in actin cytoskeletal dynamics and the evolution of multicellularity. At the molecular scale\, our work challenges the classical model of actin treadmilling through advanced single-molecule and microfluidics-assisted TIRF imaging. We have uncovered a multicomponent ecosystem at actin filament ends\, where depolymerases\, polymerases\, and blockers interact to achieve precise spatial and temporal control of filament assembly and remodeling\, reshaping our understanding of cytoskeletal self-organization. At the organismal level\, I will discuss our study on the unicellular protist Stentor coeruleus\, which illustrates how self-assembly may have contributed to early multicellular organization. Our findings indicate that hydrodynamic coupling between neighboring cells enhances feeding efficiency\, with asymmetric benefits favoring specific individuals—a potential mechanism shedding light on the selective forces driving multicellularity. Together\, these studies demonstrate how self-assembly fosters complexity and functional adaptability across scales in biological systems. \nHost: Julio Monti Belmonte

SUMMARY:CMB Seminar: Hangjie Ji
DESCRIPTION:Title: Modeling\, analysis\, and control of droplet dynamics \nAbstract: Thin liquid films flowing down vertical fibers spontaneously exhibit complex interfacial dynamics\, leading to irregular wavy patterns and traveling liquid droplets. Such droplet dynamics are fundamental components in many engineering applications\, including mass and heat exchangers for thermal desalination\, as well as water vapor and particle capture. Recent experiments demonstrate that critical flow regime transitions can be triggered by varying inlet geometries and external fields. Similar interacting droplet dynamics have also been observed on hydrophobic substrates\, arising from interfacial instabilities in volatile liquid films. In this talk\, I will describe lubrication theory and weighted residual models for falling droplets. The coarsening dynamics of condensing droplets will be described by a simplified dynamical system. I will also present our recent results on developing optimal boundary control and mean-field control for droplet dynamics.

SUMMARY:Physics Colloquium: Anna Simon-Robertson
DESCRIPTION:Title: Direct Measurements of Capture Reactions \nAbstract: Capture cross sections (both for charged particles and neutrons) are required not only for nuclear astrophysics modeling\, but also for a variety of applications ranging from nuclear energy\, stockpile stewardship to national security. A variety of techniques have been utilized to perform such measurements to ensure low uncertainty in the measured cross sections over a wide energy range. In this talk\, an overview of my group’s efforts in measurements of capture-reactions cross sections will be presented. Investigations of the charged-particle capture reactions using the gamma-summing technique will be discussed\, followed by direct methods to measure neutron capture cross sections using a newly established Neutron Irradiation Station at Notre Dame. \nHost: Richard Longland
