SUMMARY:Workshop / Seminar:Identifying coherent structures and controlling turbulent flows through deep learning
DESCRIPTION:Time and location: February 14\, 2025\, 9:30 - 10:30 am\, 2210 Lurie Engineering Center\nTo join via Zoom: https://umich.zoom.us/j/97823527756?pwd=H01BbvtuG5q02Wzb8LJvhUnvijlAIe.1\n\nAbstract: In this work we first use explainable deep learning based on Shapley explanations to identify the most important regions for predicting the future states of a turbulent channel flow. The explainability framework (based on gradient SHAP) is applied to each grid point in the domain\, and through percolation analysis we identify coherent flow regions of high importance. These regions have around 70% overlap with the intense Reynolds-stress (Q) events in two-dimensional vertical planes. Interestingly\, these importance-based structures have high overlap with classical turbulence structures (Q events\, streaks and vortex clusters) in different wall-normal locations\, suggesting that this new framework provides a more comprehensive way to study turbulence. We also discuss the application of deep reinforcement learning (DRL) to discover active-flow-control strategies for turbulent flows\, including turbulent channels\, three-dimensional cylinders and turbulent separation bubbles. In all the cases\, the discovered DRL-based strategies significantly outperform classical flow-control approaches. We conclude that DRL has tremendous potential for drag reduction in a wide range of complex turbulent-flow configurations.\n\nBio: Dr. Ricardo Vinuesa is joining the Department of Aerospace Engineering at the University of Michigan in the Fall of 2025.

SUMMARY:Well-being:\"Let's Talk\": Informal\, Drop-In Mental Health Counseling
DESCRIPTION:Trained mental health counselors are now available for drop-in conversations at different times and locations across campus\, including at Trotter\, the Spectrum Center\, South Quad\, the International Center\, and Bursley.\n\nThis informal\, confidential “office hours” style can be a great fit for students unsure about formal counseling\; for those with a specific\, time-limited concern they’d like to talk through\; or those seeking information on campus resources. Please note: this is not meant for crisis or emergency support.\n\n\"Let's Talk\" will run from January 20th 2025 to April 25th 2025. There will be no drop-ins the week of Spring Break (March 3rd - 7th). \n\nMonday: 11:00 am - 1:00 pm with Markie Silverman\, Ph.D.\, LP\, Room 2035 in Trotter Multicultural Center\nTuesday: 1:00 pm - 3:00 pm with Marcella A. Beaumont\, Ph.D.\, Room 3032 in The Spectrum Center (Michigan Union)\nWednesday: 1:00 pm - 3:00 pm with Emily Malinowski\, LMSW\, Room 1721A in South Quad Housing\nThursday: 2:00 pm - 4:00 pm with Ling Liu\, Ph.D. & Chunyu Xu\, M.Ed.\, M.S.Ed.\, Conference Room in the International Center\nFriday: 10:00 am - 12:00 pm with Kayla Douglas\, LMSW\, and Emily Powers\, LLMSW\, Room 2329B in Bursley Housing

SUMMARY:Exhibition:A Gathering
DESCRIPTION:Welcome. Make Yourself At Home.\n \nA Gathering brings together the newest works of art to enter UMMA’s collection — many on display here for the first time. \n \nAs a free\, public museum\, UMMA staff takes care of art for the benefit of the community and society at large. The works on view in this exhibition\, all brought into the Museum between 2019 and the present\, shows how institutions like UMMA are becoming more permeable to societal challenges\, and more nimble in responding to them in service to all in their communities. In this exhibition you will find works that reflect on how global migrations\, race\, gender\, and ecological change shape the way we engage with the world and inform our visions for the future.\n \nThis collection of artistic engagements with issues give us tools to envision who we want to be as individuals\, as a museum\, and as a society\, connected to one another across space and experience.\n \nSo gather here to take in these latest works of art brought here for you. Gather here to be engulfed in their forms and meanings\, to discuss their takes\, to learn\, to disagree. Gather to relax\, make a friend\, drink a coffee\, finish the daily Wordle. Gather to feel full\, to be moved and inspired by all the possible imaginations of what is yet to come.\n \nCurated by Félix Zamora Gómez Irving Stenn\, Jr. Fellow in Public Humanities & Museum Pedagogy\n\nLead support for this exhibition is provided by Lizzie and Jonathan Tisch\, the Richard and Rosann Noel Endowment\, and the University of Michigan Office of the Provost.\n

SUMMARY:Other:Leaves Under the Lens
DESCRIPTION:The leaf surface is a dynamic landscape where tiny\, specialized structures help plants interact with the world around them. Let’s bring this world into view! Join us for an exhibit that highlights the complex and often beautiful anatomy of leaves from the Matthaei collection. Plants throughout the conservatory will be paired with microscope photographs and micro-CT scans that illustrate the otherwise invisible structures that protect leaves from chewing insects\, absorb (or repel!) water\, and even recruit “bodyguards”. You won’t look at leaves the same way again! \n\nThis project is a collaboration between MBGNA and the Weber and Vasconcelos labs in the Department of Ecology and Evolutionary Biology\, led by PhD student Rosemary Glos.

SUMMARY:Workshop / Seminar:Statistics Department Seminar Series: Yixin Wang\, Assistant Professor\, Department of Statistics\, University of Michigan.
DESCRIPTION:Abstract: Causal inference traditionally relies on tabular data\, where treatments\, outcomes\, and covariates are manually collected and labeled. However\, many real-world problems involve unstructured data—images\, text\, and videos—where treatments or outcomes are high-dimensional and unstructured\, or all causal variables are hidden within the unstructured observations. This talk explores causal inference in such settings.\n\nWe begin with cases where all causal variables (including treatments\, outcomes\, covariates) are hidden in unstructured observations. These causal problems require a crucial first step\, extracting high-level latent causal factors from raw unstructured inputs. We develop algorithms to identify these factors. While traditional methods often assume statistical independence\, causal factors are often correlated or causally connected. Our key observation is that\, despite correlations\, the causal connections (or the lack of) among factors leave geometric signatures in the latent factors' support - the ranges of values each can take. These signatures allow us to provably identify latent causal factors from passive observations\, interventions\, or multi-domain datasets (up to different transformations).\n\nNext\, we tackle cases where unstructured data itself serves as either the treatment or the outcome. In these cases\, standard causal queries like average treatment effect (ATE) are not suitable—subtracting one text\, image\, or video outcome from another is meaningless. High-dimensional unstructured treatments also challenge the overlap assumption required for causal identification. To address these challenges\, we propose new causal queries: for unstructured outcomes\, we pinpoint outcome features most affected by the treatment\; for unstructured treatments\, we identify influential treatment features driving outcome differences. Finally\, we extend these ideas to decision-making algorithms\, such as optimizing natural language actions for desired outcomes.\n\nhttps://yixinwang.github.io/
