We also discuss special cases including provable near-optimal reconstruction guarantees for total-variation minimization and new techniques in super-resolution.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBio:\u003C\/strong\u003E\u003Cbr \/\u003EDeanna Needell is an assistant professor in the Mathematical Sciences Department at Claremont McKenna College. \u0026nbsp;Prior to this, she spent 2009-2011 as a postdoctoral fellow in the Mathematics and Statistics Departments at Stanford University. \u0026nbsp;She recieved her B.S. in mathematics and computer science from the University of Nevada and her M.A. and Ph.D. in mathematics from the University of California, Davis. \u0026nbsp;Her research interests include compressed sensing, randomized algorithms, functional analysis, computational mathematics, probability, and statistics. \u0026nbsp;Prof. Needell has been the recipient of awards including the Simons Foundation Collaboration Grant, 2012 IEEE Signal Processing Society Young Author Best Paper Award, and ScienceWatch Fast-Breaking Paper Award.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":"","uid":"27842","created_gmt":"2013-09-27 14:39:25","changed_gmt":"2016-10-08 02:05:00","author":"Ashlee Gardner","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2013-10-21T16:00:00-04:00","event_time_end":"2013-10-21T16:00:00-04:00","event_time_end_last":"2013-10-21T16:00:00-04:00","gmt_time_start":"2013-10-21 20:00:00","gmt_time_end":"2013-10-21 20:00:00","gmt_time_end_last":"2013-10-21 20:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1255","name":"School of Electrical and Computer Engineering"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EAhmad Beirami\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022mailto:beirami@ece.gatech.edu\u0022\u003Ebeirami@ece.gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
