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.

SUMMARY:Workshop / Seminar:Explaining the Historical Rise and Recent Decline in Social Security Disability Insurance Enrollment (joint with Maxwell Kellogg\, Magne Mogstad\, and Kuan-Ju Tseng)
DESCRIPTION:After substantial growth in the 1990s and 2000s\, enrollment in the U.S. Social Security Disability Insurance (SSDI) program has been declining since 2013. We use detailed administrative data to quantify the contributions of various factors to trends in SSDI enrollment\, focusing especially on the decline in the 2010s. A statistical decomposition suggests that the vast majority of the decline in SSDI enrollment since 2013 is attributable to declines in application rates -- and\, to a lesser extent\, award rates -- within demographic groups. There is very little contribution from changes over time in demographic characteristics\, eligibility\, or exit from SSDI. The decline in SSDI enrollment rates is disproportionately driven by older low-to-middle-skilled men with relatively severe health conditions who\, over time\, have become less likely to apply for SSDI and more likely to work. Consistent with this descriptive evidence\, we present results from a causal analysis suggesting that improved labor market opportunity for less-skilled workers is a key explanation of the decline in SSDI enrollment. We also investigate several other popular hypotheses for the decline in SSDI applications\, including lower award rates at the appeals level\, and find evidence at odds with them.

SUMMARY:Workshop / Seminar:GLNT: Eigenvarieties over CM fields and Galois representations
DESCRIPTION:Eigenvarieties are parameter spaces for certain p-adic automorphic forms of varying weight. These objects have become increasingly popular for studying the Fontaine—Mazur conjecture\, which leads us to ask what kinds of Galois representations appear on eigenvarieties. Our main result shows that for eigenvarieties for the group GL_n over a CM field\, the associated Galois representations are trianguline at all p-adic places\, resolving a conjecture of Hansen (following Kisin\, Colmez\, Bellaiche—Chenevier). The strategy of proof (which could be of independent interest) is to embed eigenvarieties for GL_n into an eigenvariety for a 2n-variable unitary group.

SUMMARY:Workshop / Seminar:Gomberg Lecture with Xiaoyang Zhu \"Exciton Sensing of Correlated Electrons\, Spins\, and Dipoles\"
DESCRIPTION:Correlation plays a central role in emergent phenomena\, such as quantum ground states and collective excitations. Here\, I will discuss what we can learn from time-domain sensing of correlation in two dimensional (2D) van der Waals (vdW) semiconductors\, where excitonic transitions are intimately related to bandgap modulation\, effectively dielectric constant\, and Pauli repulsion. In the 2D vdW magnetic semiconductor\, CrSBr\, excitonic transition is found to strongly couple to magnetic order and this allows the easy detection of low energy (GHz-THz) magnons by visible-NIR light. In the 2D vdW magnetic semiconductor\, NbOI2\, we report the experimental discovery of a quasi-particle\, the ferron\, which may form the basis for new modes of information processing and control. In twisted bilayer MoTe2\, we demonstrate exciton sensing as hitherto the most sensitive probe of electron correlation in moiré quantum matter\, including signatures for a coveted quantum phase - the fractional topological insulator.

SUMMARY:Workshop / Seminar:Student combinatorics seminar: Standard Monomials for the Grassmannian
DESCRIPTION:Given a subvariety of the Grassmannian\, a standard monomial is a monomial which does not lie in the associated initial ideal. This simple definition has proved a powerful tool for proving certain algebro-geometric properties of the subvariety. In this talk\, we'll first consider the standard monomials for the Grassmannian. We'll then look at recent work by Almousa\, Gao\, and Huang which gives a description of the standard monomials for a positroid variety in terms of a special type of semistandard tableaux. \n\nThis talk is based on the delightful paper Standard Monomials for Positroid Varieties by Almousa\, Gao\, and Huang from 2024.

SUMMARY:Lecture / Discussion:2026 Thomas Spencer Jerome Lecture Series
DESCRIPTION:Presented by Professor Edward Watts\, the Alkiviadis Vassiliadis Endowed Chair and Distinguished Professor of History at UC San Diego\, received his BA in Classics from Brown University in 1997 and his PhD in History from Yale University in 2002. His research centers on the intellectual\, political\, and religious history of the Roman Empire and the early Byzantine Empire. He is the author of seven books and the editor of five more\, including The Final Pagan Generation (UC Press\, 2015)\,  Hypatia: The Life and Legend of an Ancient Philosopher\, (Oxford University Press\, 2017)\, Mortal Republic: How Rome Fell into Tyranny (Basic Books\, 2018)\, and The Eternal Decline and Fall of Rome: The History of a Dangerous Idea (Oxford University Press\, 2021). His most recent book\, The Romans: A 2000 Year History (Basic Books\, 2025)\, traces the history of the Roman state from the 8th century BC through 1204 AD. His work has also been featured in Time\, Vox\, Smithsonian\, the Economist\, the Wall Street Journal\, the San Francisco Chronicle\, British Museum Magazine\, and the New York Times. Before coming to UCSD in 2012\, Professor Watts taught for ten years at Indiana University. He teaches courses on Byzantine History\, Roman History\, Late Antique Christianity\, Roman numismatics\, and the history of the Medieval Mediterranean. \n\nThe Roman citizen body lived an almost inconceivably long life. Between the 8th century BC and the 15thcentury AD\, nearly 100 generations of Romans superintended a political legacy they had inherited from their ancestors and handed down to their children. Nearly every element of Roman life changed during those two millennia. The state expanded from a hilltop settlement into a massive empire. Its center moved from Italy to Constantinople. Its dominant language changed from Latin to Greek. Its weaponry evolved from iron swords and bronze spears to Greek fire and gunpowder. It incorporated countless new gods before ultimately becoming Christian. And yet the thread linking the Roman present to its past never snapped. For all of their history\, Romans used this past to help understand their world and determine the contours of its future. Tradition served as a governor on the pace of necessary change.\n\nThis Thomas Spencer Jerome lecture series introduces the idea of Roman interchronological history to explain how Romans found and maintained this balance between innovation and tradition. Interchronological history recognizes that Roman scholastic\, social\, familial\, and religious traditions created situations in which Romans in the present spoke the words and felt the feelings of figures from the real or imagined past. These ancient situations encouraged people to connect personally and emotionally with figures from the past and made it natural to see in the past a set of frameworks that allowed one to both understand the present and imagine possible futures that might result from it. \n\nThese lectures explain how Roman educational\, family\, religious\, and literary culture produced this way of interpreting the present and imagining the future through deep engagement with the past. They will then show how an interchronological approach to Roman history expands our understanding of everything from the political power of Roman women to the nature of Iconoclasm and the surprising durability of the Roman bond market. By their conclusion\, the lectures will point to new ways to answer questions about the Roman past and suggest non-Roman contexts in which this historical method can also be applied.\n \nProfessor Watts will present four lectures and one seminar between March 9 and 19\, 2026: \n\n• What is Interchronological Roman History? Monday\, March 9\, 5:30 pm\, Hussey Room\, Michigan League\nThis lecture reconstructs an interchronological historical method based on how Romans were educated and socialized to connect with the words\, experiences\, and feelings of people in their shared past in a fashion that ensured their reactions in the moment and plans for the future remained connected to the traditions of the past.\n\n• Interchronological History and the Political Power of Roman Women\, Thursday\, March 12\, 5:30 pm\, Hussey Room\, Michigan League\nUsing an interchronological approach\, this lecture shows how literature\, public commemorations\, and monuments encouraged Romans of both genders to recognize the political power of Roman women by speaking the words of female political exemplars\, feeling their emotions\, and understanding the circumstances surrounding their political interventions.  \n\n• Classical Studies Graduate Student Seminar: Containerization and the Creation of Interchronological Spaces in Imperial Rome\, Friday\, March 13\, 12:00 pm \nThis seminar will look at how the creators and sponsors of a series of monuments in Rome curated space to generate an experience that joined the present in which the monument was unveiled with elements of the past to define a transition to a promised future. Using the theory of artistic containerization\, we will see how each space was designed to showcase elements of the Roman past in a way that channeled specific themes important to both the present identity of the monument’s sponsor and a future they were promising to deliver.\n\n• An Interchronological Approach to Roman Religion and Political History  Monday\, March 16\, 5\;30 pm\, Vandenberg Room\, Michigan League\nThis lecture explains how an interchronological history of Roman religion and politics can help us understand why this basic understanding of the role of the divine in shaping the tangible realities of Roman life persisted as Roman religion evolved from the practices of a small pagan city state into those of a large Christian empire.\n\n• The Failures of Justin II and the Case for Interchronological Roman Macroeconomic History\, Thursday\, March 19\, 5:30 pm\, Hussey Room\, Michigan League \nThis uses an interchronological comparative framework to reconstruct the institutional history of Roman finance and macroeconomics in order to explain how the sixth century emperor Justin II inadvertently crippled Rome's nearly 800-year-old financial system.
