High Energy Theory seminar: "An EFT approach to black hole perturbations in scalar tensor theories"
Riccardo Penco (Carnegie Mellon University)
In this talk, I will introduce an effective field theory (EFT) for perturbations around spherically symmetric spacetimes with a non-trivial scalar field profile. I will then apply this framework to study…
Mathematical Biology seminar: "Ultrastructural 3D simulations of electrical and calcium dynamics in neurons and networks"
Gillian Queisser (Temple University)
Neurons make use of their complex cellular and intracellular architecture to process and guide electrical and biochemical signals. To study this structure-function interplay, computational methods…
Astronomy seminar: "Exploring the Connection between Galaxies and their Supermassive Black Holes"
Vicki Sarajedini (Florida Atlantic University)
Active Galactic Nuclei (AGNs) are galaxies currently accreting significant amounts of material onto their central super massive black holes and may mark an important phase of galaxy evolution…
Advances in Biomedical Optics seminar series: "Human Brain Interferometers for Better Blood Flow Monitoring"
Vivek Srinivasan (University of California Davis)
Physics and Astronomy Colloquium: "Quantifying Hidden Order Out of Equilibrium"
Paul Chaikin (New York University)
We introduce a simple idea enabling the quantification of organization in non-equilibrium and equilibrium systems, even when the form of order is unknown: 'It takes less information to describe an ordered…
Condensed and Living Matter Seminar: "Bacterial swimming: internal clock and fluid environment"
Nuris Figueroa-Morales (Penn State University)
Bacterial suspensions are ubiquitous in naturally occurring and man-made scenarios. Their transport determines how infections spread and microbiota organize in guts or in soils. In addition, bacteria can turn common…
High Energy Theory seminar
Simon Ross (Durham University)
Condensed and Living Matter Seminar: "Fluid-structure interactions for energy and climate"
Ching-Yao Lai (Columbia University)
Understanding the interactions between soft structures and fluid flows is critical for a broad range of applications including energy, biotechnology, geophysics, and climate science. When fluid flows through a…
Mathematical Biology seminar: "Making Bayesian phylogenetics like training a neural network"
Erick Matsen (Fred Hutchinson Cancer Research Center)
Bayesian posterior distributions on phylogenetic trees remain difficult to sample despite decades of effort. The complex discrete and continuous model structure of trees means that recent inference…
Condensed and Living Matter Seminar: "Deconstructing how cellular interactions ensure robust morphogenesis"
Hannah Yevick (Massachusetts Institute of Technology)
Correct tissue shape is essential for its proper function. It is therefore crucial that a developing tissue robustly assembles into its target structure. To change shape, cells within a tissue must exert…
