While he often approaches questions from an experimentalist\u2019s perspective, work in his lab relies on a mixture of computational, mathematical, and microbial systems. He is predominantly drawn to understanding host-parasite coevolution because the constant push-and-pull of antagonistic interactions emphasizes the dynamic and interdependent nature of biological evolution. These antagonistic interactions have been implicated in large-scale evolutionary patterns, such as diversification, sexual reproduction, and increasing organismal complexity. How coevolution is further influenced by such large-scale patterns presents problems that orient the lab\u2019s long-term goals.", "occurrence_notes":null, "guid":"150652-21909760@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/150652", "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":["Basic Science","Evolutionary Biology","Biology","Bioinformatics"], "website":"https:\/\/umich.zoom.us\/j\/93929606089?pwd=SHh6R1FOQm8xMThRemdxTEFMWWpVdz09", "sponsors":[ { "group_name":"DCMB Seminar Series", "group_id":"3754", "website":"" }, { "group_name":"Department of Computational Medicine and Bioinformatics DCMB", "group_id":"5384", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/08\/event_150652_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/08\/event_150652_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/08\/event_150652_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/08\/event_150652_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/08\/event_150652_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/08\/event_150652_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/08\/event_150652_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/08\/event_150652_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/08\/event_150652_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/08\/event_150652_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/08\/event_150652_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/08\/event_150652_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/08\/event_150652_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/08\/event_150652_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/08\/event_150652_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/08\/event_150652_original-1.png" }, "occurrence_count":1, "first_occurrence":21909760 } , "153344-21915672": { "datetime_modified":"20261006T103517", "datetime_start":"20261014T160000", "datetime_end":"20261014T170000", "has_end_time":1, "date_start":"2026-10-14", "date_end":"2026-10-14", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"Exponential Rank Bounds for Random Matrices", "occurrence_title":"", "combined_title":"Exponential Rank Bounds for Random Matrices: Achintya Polavarapu", "event_subtitle":"Achintya Polavarapu", "event_type":"Lecture \/ Discussion", "event_type_id":"13", "description":"A basic question in random matrix theory is how likely a matrix is to have a large rank.
