This dissertation studies several mathematical problems that arise from this demand, with an emphasis on sequential decision making, sparse high-dimensional inference, differential privacy, and global testing. \n\nThe first part of the dissertation concerns stochastic convex hull membership, a pure-exploration problem in which one sequentially samples from a finite collection of distributions in order to decide whether a target point belongs to the convex hull of their unknown means. We first give a complete solution in one dimension, deriving the information-theoretic characteristic time and developing Thompson-CHM, an asymptotically optimal sampling algorithm whose allocation matches the lower bound. We then further extend the whole theory to the higher-dimensional Gaussian setting, where Euclidean geometry makes the least favorable alternatives explicit. \n\nThe second part develops differentially private procedures for the Dantzig selector in high-dimensional linear regression. We start by proposing a private sparse-regression method based on a noisy iterative hard-thresholding oracle tailored to the Dantzig selector's score geometry. The algorithm preserves sparsity by construction and satisfies privacy, parameter-error, and population excess-risk guarantees, with the main error rate matching the known differentially private minimax benchmark up to logarithmic factors. We then introduce a complementary active-set method that privatizes the Dantzig score more directly: it privately identifies violated score coordinates, refits on a restricted support, and prunes to exact sparsity. This second approach is closer to the defining feasibility constraint of the Dantzig selector and provides an alternative route to private sparse estimation under stronger sparse-design conditions.\n\nThe final part studies sparse-signal detection in high-dimensional regression by combining two classical ideas: knockoffs and higher criticism. Knockoffs provide dependence-adaptive negative controls, while higher criticism is designed to detect rare and weak alternatives near the sharp sparse-mixture boundary. We introduce a multi-knockoff higher-criticism statistic based on Lasso entry times in an augmented design containing multiple knockoff copies per feature. In the orthogonal-design regime, the proposed statistic attains the classical higher-criticism detection boundary for sparse alternatives against the global null. This result suggests a new way to use knockoff constructions beyond false discovery rate control: as a mechanism for calibrating global tests in high-dimensional models with structured dependence.", "occurrence_notes":null, "guid":"148514-21904393@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/148514", "building_id":"null", "building_name":"Off Campus Location", "campus_maps_id":"1", "room":"", "location_name":"Virtual", "has_livestream":1, "livestream_type":"other", "livetream_require_login":0, "livestream_id":"", "livestream_link":"https:\/\/umich.zoom.us\/j\/96950417537?jst=2", "cost":"", "tags":["Dissertation"], "website":"", "sponsors":[ { "group_name":"Department of Statistics Dissertation Defenses", "group_id":"4045", "website":"" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21904393 } , "147994-21902679": { "datetime_modified":"20260603T062021", "datetime_start":"20260603T103000", "datetime_end":"20260603T114500", "has_end_time":1, "date_start":"2026-06-03", "date_end":"2026-06-03", "time_start":"10:30:00", "time_end":"11:45:00", "time_zone":"America\/Detroit", "event_title":"Prompt Writing", "occurrence_title":"", "combined_title":"Prompt Writing", "event_subtitle":"", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"A 75-minute, in-person workshop for LSA Staff to learn about Prompt Writing.

For this project, Byrne, Clegg, and Narula have been commissioned to reimagine the pillars on Division Street that flank the gallery. In response, they\u2019ve curated six artists to create new work for the pillars over three cycles:\n\nPhase 1 (September 12 - December 12) artists: Amelia Burns (Cranbrook MFA \u201923) and Erin McKenna (MFA \u201920)\nPhase 2 (January 12 - August 12) artists: Sally Clegg (MFA \u201920) and Kim Karlsrud (MFA \u201920)\nPhase 3 (September 12 - November 12) artists: Abhishek Narula (MFA \u201920) and Nathan Byrne (MFA \u201921)\nPhase 2 Curatorial Statement\n\nCurated by Sometimes Space: Sally Clegg (entry pillar)\nCurated by CYNK Studios: Kim Karlsrud (courtyard pillar)\n\nArtists Sally Clegg and Kim Karlsrud wrap the Division Street pillars in highly site-specific ornament unearthed from the overlooked margins of Ann Arbor. On the Courtyard pillar, Karlsrud scales up photographs of objects found in liminal spaces surrounding campus buildings on Green Road, which the artist has encrusted in road salt. On the entryway pillar, Clegg zooms in on tiny fragments of found material from UMich\u2019s famous \u201crock\u201d to celebrate nearly seven decades of student art and activism. Both artists uplift aggregate of local human activity to reveal tiny worlds of found form. \n\nSally Clegg: Sentimentary Rock\nSentimentary Rock is a composition of paint slag collected from the UMich rock monument at the corner of Washtenaw Avenue and Hill Street. This colorful composite material has been accumulating at the base of the iconic limestone boulder since the mid 1950\u2019s, when students began a tradition of painting it in acts of protest, creativity, and ritual, sometimes multiple times per week. Akin to byproducts of industry such as \u201cFordite\u201d (collectable chunks of automotive overspray sometimes called \u2018Detroit agate\u2019), Sentimentary Rock includes thousands of layers, each dripped from a palimpsestic public proclamation. When processed, sculpted, sealed, assembled, and macro-photographed, the result is this enlarged array of tiny gems, intended to celebrate the indissoluble student voice. \n\nKim Karlsrud: What Amasses\nWhat Amasses is an assemblage of everyday found objects collected within the Miller Creek watershed, an urbanized drainage system that encompasses much of the city of Ann Arbor and the University of Michigan campus. Selected objects were immersed in a road salt solution, allowing delicate crystalline formations to emerge. Road salt is a common material input into these hydrological networks during the winter months and exists in multiple states of refinement, expression, coherence, and fragmentation. Each object was then arranged, photographed, and enlarged to recontextualize these materials in ways that invite deeper reflections on how infrastructure and human agency blur notions of the natural and the artificial. \nArtist Statements\/Bios\n\nSally Clegg \nSally Clegg is an artist and educator from Pelham, Massachusetts. Her studio practice is rooted in sculpture and expanded printmaking, stemming from a fascination with human efforts to make meaning from our relationships to objects. Clegg integrates history, popular culture, literature and philosophy as material for artmaking, leveraging personal anecdote and humor to reveal the complexity, absurdity, and theoretical richness at play in our connections to things and to ourselves. \n\nClegg holds an MFA in Art from The University of Michigan Stamps School of Art & Design, and a BA in Art & English from Goucher College. She has exhibited nationally and internationally, and her work can be found in permanent collections at Yale University, The New York Public Library, and elsewhere. Her artwork and writing has appeared in ASAP\/Journal, BOMB Magazine, Sculpture Magazine, and Hyperallergic. She is a lecturer in Art & Design at the University of Michigan. Website \/ Instagram\n\n\nKim Karlsrud \nKim Karlsrud is the co-founder of Commonstudio, a collaborative creative practice that develops socio-ecological and spatial interventions, installations, and initiatives working with and within urban landscapes. Her work explores the space between art and design, and is grounded in the concept of the \u201ccommons,\u201d that which is shared, as well as that which is ordinary, banal, and commonplace.\n\nKarlsrud completed her undergraduate degree in Product Design from Otis College of Art and Design and an MFA in Art from the University of Michigan. She is currently an Assistant Visiting Professor in the College of Design at the University of Oregon, teaching across Art and Landscape Architecture departments. She jointly received the 2014-15 Prince Charitable Trust Rome Prize in Landscape Architecture, was a 2017 resident at the Headlands Center for the Arts, and is the 2025-26 Fuller Fieldscape Fellow.
