SUMMARY:Workshop / Seminar:HEP-Astro Seminar | A frequentist view on cosmological neutrinos and dark-energy constraints
DESCRIPTION:The DESI galaxy survey has recently placed the tightest constraint on the sum of neutrino masses to date. For such effects “below the detection limit”\, where data can only infer upper bounds\, Bayesian and frequentist methods can give important complimentary information. I will begin with an overview of the frequentist profile-likelihood method\, its advantages and limitations. Using a frequentist and Bayesian toolbox\, I will discuss neutrino mass constraints from Planck and DESI data. In particular\, I will focus on the impact of different assumptions about the neutrino mass hierarchy on the inferred mass bounds. Further\, I will compare Bayesian and frequentist constraints on evolving dark energy from recent cosmological data.

SUMMARY:Lecture / Discussion:Intersections of AI\, Photonics\, and Scientific Discovery
DESCRIPTION:Abstract: Artificial intelligence is beginning to transform the way we do science and engineering—not only by analyzing data\, but increasingly by generating hypotheses\, designing experiments\, and even running them. Photonics plays a dual role in this story: it provides some of the most promising physical platforms for AI hardware\, while also serving as a rich testbed for applying AI itself. I will discuss how conventional “black box” AI and more interpretable approaches can both uncover structure in complex systems\, and how large language models point toward a future where significant parts of scientific discovery may be automated. I will also highlight how robotics\, combined with AI\, is moving us closer to self-driving laboratories. While my examples will often come from photonics\, the broader message is that these developments foreshadow a profound shift in how science is practiced across disciplines.\n\nBio: Marin Soljačić is a Professor of Physics at MIT.

SUMMARY:Workshop / Seminar:MCDB Seminar> Microenvironmental sensing by intestinal stem cells promotes adult Drosophila intestinal regeneration
DESCRIPTION:A failure to properly maintain or regenerate an epithelium results in the loss of its integrity\, architecture and function\, and thus also organismal homeostasis. In many adult epithelia\, stem cells divide to replace damaged or lost tissue cell types. Stem cells are coaxed to proliferate by signalling cues produced by cells in the regenerative microenvironment that forms shortly after injury. Cells within this microenvironment can include other epithelial cells as well as other cell types and tissues associated with the organ. While much is known about how signalling cues from the regenerative microenvironment promotes stem cell proliferation in several adult epithelia\, we know less about how stem cells sense damage or even damage-causing pathogens and how they translate this information to modify their behaviour for regeneration. Furthermore\, even less is understood about how stem cells modulate their microenvironment after tissue damage to support regeneration. \n\nUsing the adult Drosophila intestine (or midgut)\, we have uncovered mechanisms that allow intestinal stem cells (ISCs) to recognise tissue damage as well as invading pathogens and translate this into their proliferation for regeneration. Moreover\, we have found that after damage\, these same ISC pathways can shape the regenerative microenvironment.\n\nHost: Laura Buttitta

SUMMARY:Workshop / Seminar:Perturbation of mixed characteristics test ideal
DESCRIPTION:Given a normal domain R of finite type over a mixed characteristic complete DVR or a perfect field of characteristic p\, one can define the notion of a test ideal. In equal characteristic p\, it is well known that test ideals are stable under small perturbations. The proof of this fact boils down to a fundamental result in Smith's thesis on tight closure\, which states that there are no nonzero almost zero elements in the top local cohomology of R^+.In this talk\, I will explain how to extend this result to the mixed characteristic setting\, along with its applications to mixed characteristic test ideals. Time permitting\, I will also outline the key ideas behind the proof. This is joint work in progress with Bhargav Bhatt and Linquan Ma.

SUMMARY:Workshop / Seminar:RCGD Seminar Series on Social Connection: Kristina Smiley
DESCRIPTION:Kristina Smiley\nUniversity of Michigan\nHow Hormones and Sensory Cues Shape the Parental Brain\nMarch 9\, 2026\n\nABOUT THE SERIES\n\nThe Winter 2026 RCGD Seminar Series: The Ties that Bond: Interdisciplinary Perspectives on Social Connection\n\nThis seminar series brings together senior and early-career scholars to explore fundamental questions about how we connect\, protect\, and care. Talks will highlight lifespan and comparative approaches to understanding social connection\, physiological implications of social and race-related stressors\, and diverse conceptualizations of what it means to belong—from romantic and parent–child relationships to group and societal dynamics to technology-mediated interactions.\n\nRobin Edelstein\, Professor of Psychology at the University of Michigan and an affiliate of the Research Center for Group Dynamics\, has organized this series. She will introduce the series at this kick-off event that doubles as a faculty meeting.\n\nThe first seminar in the series will be Jan. 26. Join us on Mondays to learn about the biological\, social\, and developmental pathways that shape human connection.\n\nThese events are held Mondays from 3:30 to 5.\nIn person: ISR Thompson 1430\, unless otherwise specified.\nOrganized by Robin Edelstein\nAs permissions allow\, seminars are later posted to our YouTube playlist.

SUMMARY:Livestream / Virtual:An introduction to Dirac geometry and reduction schemes for concurrent Dirac structures.
DESCRIPTION:I will provide first a gentle introduction to Dirac geometry\, which is a way to unify pre-symplectic and Poisson geometry\, as well as turning possibly singular Poisson structures into a perfectly smooth object. \n\nAfter this\, I will consider a particular situation of transferring Dirac structures which is the following:\ngiven an embedded submanifold X of a Dirac manifold (M\, L_M) and given p: X -> Y a smooth surjective submersion\, we want to derive the minimal set of conditions to transfer the Dirac structure L_M on M to a Dirac structure L_Y on Y. These conditions are however not compatible with concurrence\, which is a generalization for Dirac structures of the notion of commuting Poisson pairs. \n\nThen I will characterize a geometric structure\, more precisely a vector bundle E\subset TM|_X that is a \emph{witness} for concurrence: it allows to transfer weakly concurrent Dirac structures on M to weakly concurrent Dirac structures on Y. We show that the Marsden-Ratiu reduction in Poisson geometry is exactly a special case of this construction. Furthermore\, in the presence of a Hamiltonian action of a Lie group G on L_M\, there is a natural candidate for a witness E. \n\nThe main results carry over to the case of complex Dirac structures. This allows us to give an extension of the bi-Hamiltonian reduction of Casati\, Magri e Pedroni in terms of our framework and provide a (conjectural) interpretation of it in terms of complex Dirac structures. \n\nThis talk is based on a joint work with Dan Aguero\, Pedro Frejlich and Igor Mencattini.
