SUMMARY:Workshop / Seminar:Fe-mediated N2-fixation and lessons for other metals: Bridging catalysis\, electrocatalysis\, and photocatalysis
DESCRIPTION:Nitrogen reduction to ammonia is a requisite transformation for life and there is growing interest in developing sustainable technologies for ammonia synthesis using renewably sourced energy. Such approaches may some day lead to distributed on-demand fertilizer production and enable ammonia to be used as a zero-carbon alternative fuel. Our group has had an ongoing interest in fundamental studies of well-defined synthetic catalysts that mediate nitrogen reduction (N2R) to ammonia (or hydrazine). We are especially interested in the operative mechanisms by which these catalysts operate. Most recently\, we have been pursuing the idea that proton-coupled electron transfer (PCET) pathways for N2R can be more thermally efficient than step-wise ET/PT pathways and have tested this hypothesis via the development of electrochemical PCET (ePCET) mediators driven at potentials sufficiently anodic that the competing hydrogen evolution reaction (HER) is mitigated. We have also designed related electrocatalytic strategies that exploit an ET instead of a PCET mediator. Relatedly\, we are studying catalytic systems that mediate photodriven and (photo)electrochemical N2R. Here\, visible light rather than temperature\, pressure\, or electrochemical potential\, provides the primary driving force needed for catalytic ammonia generation. Again\, we are especially interested in the intimate mechanisms by which these various systems operate.

SUMMARY:Workshop / Seminar:GLNT: A local sign decomposition for symplectic self-dual Galois representations of rank two
DESCRIPTION:We present a new structure on the first Galois cohomology of families of symplectic self-dual p-adic representations of $G_Qp$ of rank two. This is a functorial decomposition into free rank one Lagrangian submodules encoding Bloch-Kato subgroups and epsilon factors\, mirroring an underlying symplectic structure.\n\nThis local sign decomposition has local as well as global applications\, including compatibility of the Mazur-Rubin arithmetic local constants and epsilon factors\, and new cases of the parity conjecture. It also leads to a formulation and proof of an analogue of Rubin's conjecture over ramified quadratic extensions of Qp\, which initiates an integral Iwasawa theory for CM elliptic curves at primes of additive reduction. (Joint with S. Kobayashi\, K. Nakamura\, and K. Ota.)

SUMMARY:Workshop / Seminar:Local cohomology modules supported at determinantal nullcones
DESCRIPTION:Abstract: We will discuss the local cohomology modules supported at the nullcone ideal for the classical actions of the linear algebraic groups. We calculate the arithmetic rank of the nullcone ideals in every characteristic and establish sharp vanishing results for local cohomology modules supported at these ideals over any commutative Notherian ring which mirror the corresponding results for determinantal ideals. This is joint work with Jack Jeffries\, Anurag Singh\, and Uli Walther.

SUMMARY:Lecture / Discussion:Relational Technologies and Indigenous STEM (Science\, Trickers\, Ecology\, and Matriarchs)
DESCRIPTION:This talk explores how Anishinaabe (Neshnabe) philosophies of futurity offer alternative frameworks for science\, technology\, engineering\, and mathematics—reimagined here as Science\, Trickers\, Ecology\, and Matriarchs (STEM). Drawing from my book\, Mapping Neshnabe Futurity\, I examine how Indigenous knowledge systems—rooted in land-based ethics\, intergenerational responsibility\, and reciprocal relationships—function as sophisticated technologies for sustaining ecosystems and communities. Central to this approach are both women-led political movements and trickster methodologies. Figures like Nanabozho embody creativity\, misdirection\, and transformation\, showing how experimentation\, surprise\, and humor can drive innovation. Trickster thinking unsettles linear notions of progress\, inviting scientific practices that are adaptive\, relational\, and open to unexpected outcomes.\n\nRather than treating “technology” as merely mechanical or digital\, I highlight how Indigenous worldviews understand technology as relational: practices for maintaining balance between human and more-than-human worlds. Examples include sustainable water stewardship\, climate adaptation\, and culturally grounded mapping projects that foreground Anishinaabe languages and histories. By bringing Indigenous studies into conversation with STEM fields\, this talk argues for futures where scientific inquiry is inseparable from ethics of care and responsibility. Through Indigenous futurisms and trickster methodologies\, we can envision and build worlds that are innovative\, just\, and ecologically thriving.\n\nBlaire Morseau is a citizen of the Pokagon Band of Potawatomi Indians and Assistant Professor in the Department of Religious Studies at Michigan State University where she is also affiliate faculty in Digital Humanities and American Indian and Indigenous Studies. Before becoming a professor\, she worked as her tribe's first full-time archivist\, launching an online collections and dictionary website called Wiwkwébthëgen (We-oh-kweb-jug-gin) using Potawatomi cultural protocols of access and traditional knowledge labels. \n\nAs Co-Director of The Indigenous Chicago Project\, Blaire also helped shape the project's components which include oral histories\, digital maps\, curricular materials and more\, that explore the histories of the region\, centering Indigenous voices\, laying bare stories of settler-colonial harm\, and gesturing toward Indigenous futures. She recently released an edited volume featuring the collection of antique birch bark books written by nineteenth century Potawatomi author\, Simon Pokagon\, titled\, As Sacred to Us: Simon Pokagon’s Birch Bark Stories in their Contexts\, published by Michigan State University Press.\n\nDr. Morseau consults on various exhibitions and collaborative programming for archives\, libraries\, and museums around the country including the Field Museum of Natural History\, The Newberry Library\, and The Indiana University Museum of Archaeology and Anthropology. Her research interests are in Indigenous science fiction and futurisms\, traditional cultural and ecological knowledge\, digital heritage\, and Native counter-mapping. Her newest book project published in May 2025 with the University of Arizona Press\, is titled Mapping Neshnabé Futurity: Celestial Currents of Sovereignty in Potawatomi Skies\, Lands\, and Waters. The monograph investigates how Native peoples in the Great Lakes region leverage their traditional knowledge in environmental activism and in creative works of speculative fiction to reclaim Indigenous space and tribal sovereignty.

SUMMARY:Workshop / Seminar:Student Combinatorics Seminar: McMullen's g-conjecture
DESCRIPTION:A simplicial polytope P is the convex hull of finitely many points in R^d such that all the faces of P are simplices. To each such polytope\, we can associate its f-vector\, which is the integer vector recording the number of faces of each dimension. McMullen conjectured that the f-vectors of simplicial polytopes are completely characterized by three strikingly simple conditions. The sufficiency of these conditions was proved by Billera and Lee\, and the necessity was proved by Stanley using Hodge theory.\nIn this talk\, we will review the construction of toric varieties from polytopes and intersection cohomology. We will then give a brief account of Stanley's proof of the necessity part of the g-conjecture.

SUMMARY:Workshop / Seminar:The Impact of Privatization: Evidence from the Hospital Sector
DESCRIPTION:Government ownership in the U.S. hospital sector\, which accounts for 5.3% of U.S. GDP\, has steadily declined for decades.  A key driver has been the privatization of hospitals owned by local governments. Theory predicts that privatization will improve hospital profitability\, but may be socially inefficient. We test these predictions empirically by leveraging all 254 privatizations that occurred between 2001 and 2018. Privatization increases hospital profitability\,  eliminating the need for subsidies. However\, we also find a reduction in access for Medicaid patients and an increase in mortality among elderly Medicare patients. On average\, privatization generates $0.6 million in savings per additional death.
