I will share lessons learned about\nleadership, collaboration, resilience, and the importance of remaining open to unexpected opportunities.\n\nI hope to encourage students to build a strong foundation, stay curious, embrace opportunities, and recognize that a meaningful career does not always follow a predictable path.\n\nBiography \nDr. Irina Dolinskaya is the Directorate Head for Computer and Information Science and Engineering at the U.S. National Science Foundation (NSF). Previously, she served as Deputy Division Director and Program Director at NSF and as a faculty member in Industrial Engineering and Management Sciences at Northwestern University.\n\nA proud Michigan alumna, Dr. Dolinskaya earned her M.S. and Ph.D. in Industrial and Operations Engineering from the University of Michigan and her B.S. in Industrial Engineering from the University of Florida. Her research focuses on transportation science and logistics, including humanitarian logistics, vessel performance, and electric vehicle routing. She credits her education at Michigan as an important foundation for her academic and professional journey.", "occurrence_notes":null, "guid":"150647-21909755@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/150647", "building_id":"1000397", "building_name":"Lurie Robert H.

Indeed, just as M_{1,1} = A_1 is the quotient H\/SL_2(Z), one can show that A_g, the space of principally polarized abelian varieties of dimension g, is isomorphic to H_g\/Sp_{2g}(Z). More generally, one can consider spaces H_g\/Gamma for any arithmetic subgroup Gamma in Sp_{2g}(Q). Unlike M_g, which admits the canonical Deligne-Mumford compactification, these spaces admit many natural compactifications with different geometric properties. In this talk, we introduce H_g\/Gamma, the Siegel modular varieties, and discuss various compactifications such as the Baily\u2013Borel compactification and toroidal compactifications. We then focus on the specific case of g = 2 to showcase the beautiful arithmetic that occurs even in this small case.", "occurrence_notes":null, "guid":"154655-21918147@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/154655", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"2866", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics"], "website":"", "sponsors":[ { "group_name":"Student Algebraic Geometry Seminar - Department of Mathematics", "group_id":"4904", "website":"" }, { "group_name":"Department of Mathematics", "group_id":"3791", "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":21918147 } }
