Born and raised in Jamaica, Whyte completed a BFA from Bennington College and earned an MFA from the University of Michigan. He is currently a faculty member at the School of the Arts and Architecture, UCLA.\n\nThis exhibition brings together two central concerns that animate Whyte\u2019s artistic practice: the archive, both personal and public, as a site of disturbance; and migration as a lived experience of refuge, refusal, and reinvention. In Whyte\u2019s work, the archive is never static or neutral. Rather, it is a contested space where official histories encounter memory, inheritance, and the fragments of stories carried across generations. His practice moves within this charged interstitial terrain, between what has been recorded and what has been remembered, between institutional knowledge and embodied experience. Whyte invites the viewer to consider the fluidity of geographic borders and layered cultural identities that have persisted despite societal unrest caused by racial and socio-economic hierarchies across generations. In an era of intensified border politics and renewed debates over national identity, Whyte\u2019s work offers a timely meditation on memory, movement, and belonging.\n\nPresented with support from the U-M Institute for Humanities, the U-M LSA Center for Latin American and Caribbean Studies, and the U-M Library.", "occurrence_notes":null, "guid":"149541-21906623@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/149541", "building_id":"null", "building_name":"Off Campus Location", "campus_maps_id":"1", "room":"", "location_name":"Stamps Gallery, 201 South Division Street Ann Arbor, Michigan 48104", "has_livestream":0, "cost":"", "tags":["Art"], "website":"https:\/\/stamps.umich.edu\/events\/cosmo-whyte-under-the-quiet-beyond-the-eye", "sponsors":[ { "group_name":"Penny W Stamps School of Art & Design", "group_id":"3157", "website":"http:\/\/stamps.umich.edu\/" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/09\/event_149541_original-4.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/09\/event_149541_original-4.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/09\/event_149541_original-4.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/09\/event_149541_original-4.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/09\/event_149541_original-4.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/09\/event_149541_original-4.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/09\/event_149541_original-4.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/09\/event_149541_original-4.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/09\/event_149541_original-4.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/09\/event_149541_original-4.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/09\/event_149541_original-4.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/09\/event_149541_original-4.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/09\/event_149541_original-4.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/09\/event_149541_original-4.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/09\/event_149541_original-4.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/09\/event_149541_original-4.jpg" }, "occurrence_count":67, "first_occurrence":21906594 } , "152812-21914560": { "datetime_modified":"20260924T105357", "datetime_start":"20261022T120000", "datetime_end":"20261022T130000", "has_end_time":1, "date_start":"2026-10-22", "date_end":"2026-10-22", "time_start":"12:00:00", "time_end":"13:00:00", "time_zone":"America\/Detroit", "event_title":"DCMB Tools and Technology Seminar by Abhirath Anand (Computational Medicine & Bioinformatics)", "occurrence_title":"", "combined_title":"DCMB Tools and Technology Seminar by Abhirath Anand (Computational Medicine & Bioinformatics): \"hospitraceR: An R Package for WGS-Based Genomic Epidemiological Analysis of Healthcare-Associated Infections\u201d", "event_subtitle":"\"hospitraceR: An R Package for WGS-Based Genomic Epidemiological Analysis of Healthcare-Associated Infections\u201d", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Join us for the DCMB Tools & Technology Seminar Series featuring a presentation by Abhirath Anand from the Department of Computational Medicine & Bioinformatics.

As high-throughput WGS becomes more affordable, software that facilitates the analysis of this genomic data along with patient metadata becomes crucial to generate timely insights. Prior studies have shown that there can be many different approaches to detect transmission clusters with genomic epidemiology data, and oftentimes these approaches will have tradeoffs more or less suitable for a certain dataset. We present hospitraceR, an R package designed to facilitate such analyses. hospitraceR includes functions for detecting transmission clusters with two different methods, the standard SNV threshold approach and a threshold-free approach. It also includes functions that can use patient movement information through the facility to suggest potential transmission explanations for the clusters. hospitraceR seeks to enable users to use multiple methods of transmission cluster detection and compare them easily using cluster comparison metrics. Metrics like the adjusted Rand Index (ARI) and adjusted mutual information (AMI) have been included for this purpose, as has fraction of converts with shared source (FSS), a custom metric designed specifically for comparing transmission clusters. A companion package, hospitraceRvisualize, also includes opinionated plotting functions for certain commonplace visualizations that aid in epidemiological interpretations. We apply hospitraceR to a dataset consisting of 4 long-term acute care hospitals (LTACHs) from Chicago sampled for different periods of time as part of an intervention study and evaluate the two different approaches for cluster detection. We find distinct patterns exhibited by the transmission clusters in different locations and also compare the different clusters obtained with different SNV thresholds and linkage criterion for hierarchical clustering. The hospitraceR package proves to be helpful in facilitating such comparisons and makes it easy to use WGS data to aid epidemiological investigation.", "occurrence_notes":"MS1 B-Wing", "guid":"152812-21914560@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/152812", "building_id":"1000190", "building_name":"Medical Science Unit I", "campus_maps_id":"104", "room":"4B700", "location_name":"Medical Science Unit I", "has_livestream":0, "cost":"", "tags":["Bioinformatics","Biology","Biosciences","Genome","Life Science","Precision Health"], "website":"https:\/\/medschool.umich.edu\/events\/tools-technology-seminar-series\/dcmb-tools-technology-seminar-abhirath-anand\/2026-10-22", "sponsors":[ { "group_name":"Department of Computational Medicine and Bioinformatics DCMB", "group_id":"5384", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/09\/event_152812_original-1.webp", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/09\/event_152812_original-1.webp", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/09\/event_152812_original-1.webp", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/09\/event_152812_original-1.webp", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/09\/event_152812_original-1.webp", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/09\/event_152812_original-1.webp", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/09\/event_152812_original-1.webp", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/09\/event_152812_original-1.webp", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/09\/event_152812_original-1.webp", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/09\/event_152812_original-1.webp", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/09\/event_152812_original-1.webp", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/09\/event_152812_original-1.webp", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/09\/event_152812_original-1.webp", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/09\/event_152812_original-1.webp", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/09\/event_152812_original-1.webp", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/09\/event_152812_original-1.webp" }, "occurrence_count":1, "first_occurrence":21914560 } }
