- 10:00 AM6hInk, Stone, and Silver Light: A Century of Cultural Heritage Preservation in AleppoOn view October 1 -- December 11, 2025This exhibition draws on archival materials from the Aga Khan Documentation Center at MIT (AKDC) to explore a century of cultural heritage preservation in Aleppo, Syria. It takes as its point of departure the work of Kamil al-Ghazzi (1853–1933), the pioneering Aleppine historian whose influential three-volume chronicle, Nahr al-Dhahab fī Tārīkh Ḥalab (The River of Gold in the History of Aleppo), was published between 1924 and 1926.Ink, Stone, and Silver Light presents three modes of documentation—manuscript, built form, and photography—through which Aleppo’s urban memory has been recorded and preserved. Featuring figures such as Michel Écochard and Yasser Tabbaa alongside al-Ghazzi, the exhibition traces overlapping efforts to capture the spirit of a city shaped by commerce, craft, and coexistence. At a time when Syria again confronts upheaval and displacement, these archival fragments offer models for preserving the past while envisioning futures rooted in dignity, knowledge, and place.
- 10:00 AM7hExhibition: Remembering the FutureJanet Echelman's Remembering the Future widens our perspective in time, giving sculptural form to the history of the Earth's climate from the last ice age to the present moment, and then branching out to visualize multiple potential futures.Constructed from colored twines and ropes that are braided, knotted and hand-spliced to create a three-dimensional form, the immersive artwork greets you with its grand scale presiding over the MIT Museum lobby.This large-scale installation by 2022-2024 MIT Distinguished Visiting Artist Janet Echelman, was developed during her residency at the MIT Center for Art, Science & Technology (CAST). Architect, engineer and MIT Associate Professor Caitlin Mueller collaborated on the development of the piece.The title, Remembering the Future was inspired by the writings commonly attributed to Søren Kierkegaard: "The most painful state of being is remembering the future, particularly the one you'll never have."As the culmination of three years of dedicated research and collaboration, this site-specific installation explores Earth's climate timeline, translating historical records and possible futures into sculptural form.Echelman's climate research for this project was guided by Professor Raffaele Ferrari and the MIT Lorenz Center, creators of En-ROADS simulator which uses current climate data and modeling to visualize the impact of environmental policies and actions on energy systems.Learn more about Janet Echelman and the MIT Museum x CAST Collaboration.Learn more about the exhibition at the MIT Museum.
- 12:00 PM1hCog Lunch: Andrea de VardaLocation: 46-3310Zoom: https://mit.zoom.us/j/96224282850Speaker: Andrea de VardaAffiliation: EvLab & Levy LabAbstract: Large language models (LLMs) have recently emerged as powerful candidates for modeling several domains of human cognition. Because they operate over natural language, they provide flexible representations that can be evaluated against human behavior and brain activity. In this talk, I will present two studies that use LLMs to test how far this modeling approach can go—first in the domain of language, and then in higher-level reasoning. In the first part, I ask whether multilingual language models can explain how the human brain processes the extraordinary diversity of the world's languages. Using fMRI data from native speakers of 21 languages spanning 7 language families, we show that model embeddings reliably predict brain responses within languages and, crucially, transfer zero-shot across languages and families. These results point to a shared representational component in the human language network, largely driven by semantic content, that aligns with the representations learned by multilingual models. In the second part, we move beyond language to ask whether LLMs can also serve as models of human reasoning. Here the question is not only whether models arrive at the correct answers, but whether they capture the cognitive cost associated with the reasoning process. Analyzing large reasoning models (LLMs further trained to generate explicit chains of thought), we show that the number of reasoning steps they take predicts human reaction times across seven diverse reasoning tasks, from arithmetic to relational inference. This alignment holds both within tasks, reflecting item difficulty, and across tasks, capturing broad differences in cognitive demand. Together, these studies show that models optimized on language can capture human brain responses to linguistic input across diverse languages, and reasoning-trained variants of these models can mirror the costs of higher-order cognition.

- 2:30 PM1hPhysical Mathematics SeminarSpeaker: Maria Avdeeva (Flatiron Institute)Title: A generative model of the first cell fate decision in mammalian developmentAbstract:The first cell fate bifurcation in mammalian development—the segregation of the trophectoderm (TE) and inner cell mass (ICM)—unfolds across asynchronous cell divisions, making its dynamics extremely challenging to reconstruct from fixed embryos. To overcome this, we developed a framework combining quantitative live imaging of key regulatory proteins with a generative probabilistic model, an approach broadly applicable to non-deterministic systems where live imaging is feasible. Our model fuses partial, pairwise observations of the transcriptional co-activator YAP with its targets, CDX2 (TE) and SOX2 (ICM), to reveal the joint dynamics of the complete regulatory network. This approach uncovered the time-dependent statistics of the cell fate allocation and allowed us to identify specific features of YAP's dynamic behavior necessary or sufficient for downstream gene induction. Notably, we uncovered significant temporal heterogeneity in SOX2 induction among ICM cells. Heterogeneities within the ICM have been linked to the initiation of the second cell fate decision in the embryo. Our work therefore sets the stage for dissecting subsequent lineage decisions and understanding how stochasticity in cell fate allocation leads to robust developmental outcomes, such as precise cell fate proportions and spatial patterning.

- 3:00 PM1hHarvard–MIT Algebraic Geometry SeminarSpeaker: Roberto Svaldi (Università degli Studi di Milano)Title: Boundedness theorems for fibered varieties with trivial canonical bundleAbstract:I will explain ideas and techniques behind recent new results showing that several classes of fibered varieties with trivial canonical bundle are bounded, that is, they are parametrised by finitely many families of deformations. Namely, I will show how abelian or K3 fibered Calabi—Yau varieties are bounded, up to simple birational equivalences, in the algebraic category, and how the same results holds in the analytic category for Lagrangian holomorphic symplectic varieties. This is joint work with Engel, Filipazzi, Greer, Mauri.
- 3:00 PM1hPDE/Analysis SeminarSpeaker: Andreas Wieser (Institute for Advanced Study)Title: Effective equidistribution of periodic orbits of semisimple groupsAbstract: Qualitatively, actions of unipotent groups on homogeneous spaces are very well understood after breakthrough works of Ratner from the 90's. The past two decades have seen dramatic progress in providing rates in these results. In this talk, we will be interested in the distributional properties of periodic orbits of semisimple groups. Here, the desire is to show that such a periodic orbit 'approximates' a periodic orbit of a larger group with a rate that is polynomial in the volume.In joint work with Einsiedler, Lindenstrauss, and Mohammadi, we prove such a result for compact (congruence) quotients with a rate this is explicit in all aspects (including the volume of the ambient space). This relies heavily on a variety of tools including uniformity of the spectral gap for periodic orbits in congruence quotients and polynomial properties of unipotent flows. We will discuss these results with an emphasis on the dynamical methods and mention applications in number theory briefly.

- 4:30 PM1hNumber Theory SeminarSpeaker: Harris Daniels (Amherst College)Title: Near coincidences and nilpotent division fields of elliptic curvesAbstract:A natural question about the division fields of a fixed elliptic curve $E/\mathbb{Q}$ is whether there is a coincidence between the division fields. I.e. Are there distinct integers $m eq n$ such that the $m$-division field equals the $n$-division field. In 2023, Daniels and Lozano-Robledo gave partial answers to this question, using (among other tools) the fact that the $n$-th roots of unity often fail to lie in the $m$-division field, thereby preventing such coincidences.Motivated by this, we consider a broader notion of \emph{near coincidences}: when does there exist $E/\mathbb{Q}$ and distinct $m,n$ such that $$ \mathbb{Q}(E[n]) = \mathbb{Q}(E[m], \zeta_n)? $$ In the first part of this talk, we answer this question completely in the case where $m$ and $n$ are powers of the same prime.In the second part, we turn to a seemingly unrelated but natural problem: classifying all elliptic curves $E/\mathbb{Q}$ and positive integers $n$ such that $$ \operatorname{Gal}(\mathbb{Q}(E[n])/\mathbb{Q}) $$ is a nilpotent group. This question generalizes the classification of abelian division fields obtained by Gonz\'alez-Jim\'enez and Lozano-Robledo (2016). We present a conditionally complete classification of nilpotent division fields, under either a standard conjecture about rational points on modular curves attached to normalizers of non-split Cartan subgroups or a full classification of the Mersenne primes. This is joint work with Jeremy Rouse.

The ensemble has garnered many positive reviews such as Downbeat Editor's Pick, The Boston Globe 2018 Best Jazz Albums, Top Ten Recordings of 2018 (Cadence Magazine) and the Jazz Journalists Association Best of 2018 (Large Ensemble) List. She currently resides in Boston where she is the Assistant Chair of Harmony and Jazz Composition at Berklee College of Music and is a Jazz Composers Present Artist."The bandleader conducts an agile, 17-piece ensemble made up of peers, friends, longtime collaborators and even family... Inserto has crafted a program that feels completely natural as big band music and includes five of her compositions. Some lesser orchestrators nowadays falter when they seize music originally penned for a combo and clumsily rework it with an arrangement that's actually ill-suited for a large ensemble. But Inserto-who studied with Bob Brookmeyer (1929-2011)- delivers a program that gracefully exploits the strengths of big band instrumentation, as evidenced by her two-part suite titled "Part I: Ze Teach" and "Part II: And Me." Elsewhere, Inserto offers a superb arrangement of Jones' "BJ's Tune," providing a showcase for the trumpeter's sumptuous tone. This album strikes the perfect balance between entertaining artistry and finely crafted arrangements that could be studied closely in the classroom."
