  • Condensed Matter Seminar: Design of Biotic-Abiotic Interfaces using Liquid Crystals

    A4

    Professor Nicholas Abbott, University of Wisconsin

    Many biological molecules form liquid crystalline phases.  The unique combination of long-range molecular ordering and mobility found in liquid crystals has been exploited by nature to create a range of functional and living systems.  We are pursuing studies that seek to create synthetic liquid crystalline materials that recapitulate biological design principles and can be used to couple biotic and abiotic systems in useful ways.

  • Condensed Matter Seminar: Microfluidic Pathways towards Topological Defect Templates

    A4

    Professor Anupam Sengupta, MIT

    Liquid crystals (LCs) are mesogenic phases of matter which combine liquid fluidity with crystalline solid properties.The material anisotropy allows us to explore LCs as complex functional materials for microfluidics. Harnessing the anisotropic coupling between the flow and the molecular ordering renders a novel perspective to the conventional concepts in microfluidics.

  • Condensed Matter Seminar: “Making Cells with Active Micro-tubule Mixtures”

    A4

    Professor Jennifer Ross, UMass Amherst

    Biology utilizes energy to organize itself from the nanoscale to the macroscopic scale. We seek to determine the universal principles of organization from the molecular scale that gives rise to architecture on the cellular scale. We are specifically interested in the organization of the microtubule cytoskeleton, a rigid, yet versatile network in most cell types. Microtubules in the cell are organized by motor proteins and crosslinkers.

  • Astronomy Seminar: Massive Galaxy Growth since Cosmic Noon

    DRL A6

    Stijn Wuyts (MPE Garching)

    The Hubble Space Telescope and integral-field spectrographs on the
    ground offer us an unprecedented view of the internal physics within
    high-redshift galaxies.  Exploiting the powerful synergy between
    multi-band high-resolution imaging from CANDELS and spectroscopy from
    3D-HST, SINS, and KMOS^3D, I will present new insights on resolved
    stellar populations, bulge growth and quenching since z ~ 2.5, as well
    as dynamical constraints on the mass budget in early disks.  I will
    emphasize the importance of using both stellar and gaseous tracers to
