In order for this `muco-ciliary clearance\u0026#39; to be effective,\u0026nbsp;cilia motion needs to be phase-locked across significant distances, in the form of a travelling wave,\u0026nbsp;and it is not known how this is achieved.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EOur lab is currently approaching this question from two directions:\u0026nbsp; recently we have begun imaging\u0026nbsp;ciliated cell carpets, quantifying the spatial and temporal coherence in the dynamics, and perturbing\u0026nbsp;the system;\u0026nbsp;we aim to match the understanding gained at that level with our previous work on model systems, which informed us of the importance of hydrodynamic coupling between driven\u0026nbsp;oscillators, as a mechanism sufficient to establish collective large-scale dynamical patterns.\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Collective dynamics in motile cilia: waves in the airways"}],"uid":"27664","created_gmt":"2017-02-24 19:30:35","changed_gmt":"2017-04-13 21:12:38","author":"Alison Morain","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2017-03-10T13:00:00-05:00","event_time_end":"2017-03-10T14:00:00-05:00","event_time_end_last":"2017-03-10T14:00:00-05:00","gmt_time_start":"2017-03-10 18:00:00","gmt_time_end":"2017-03-10 19:00:00","gmt_time_end_last":"2017-03-10 19:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"126011","name":"School of Physics"},{"id":"1278","name":"College of Sciences"}],"categories":[],"keywords":[{"id":"960","name":"physics"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78751","name":"Undergraduate students"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003Eamorain@gatech.edu\u003C\/p\u003E\r\n","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
