By combining high-speed imaging, micro-CT imaging, kinematic analyses, and fluid property measurements, \u003Cstrong\u003EAim 1\u003C\/strong\u003E\u0026nbsp;will seek to uncover how biological morphology and rapid actuation enable droplet detachment in the spotted lanternfly (\u003Cem\u003ELycorma delicatula\u003C\/em\u003E), revealing a developmental mechanism switch from a capillary ratchet in nymphs to an elastic catapult in adults. \u003Cstrong\u003EAim 2\u003C\/strong\u003E\u0026nbsp;will develop reduced-order mathematical models to capture the underlying physics of these distinct ejection strategies and integrates these models into a scaling framework using dimensionless parameters across organisms. Finally, \u003Cstrong\u003EAim 3\u003C\/strong\u003E\u0026nbsp;will map the actuator and droplet response phase spaces to establish the theoretical kinematic limits of these ultrafast rotational movements and analyze divergent post-launch spinning droplet dynamics. Together, this work will fill critical gaps in our understanding of fluid-ejecting biological systems and provide general design principles for novel bioinspired fluid transport and antifouling devices.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cstrong\u003EUltrafast Fluid Ejection in Biological Systems: The Spotted Lanternfly as a Dual-Mechanism Honeydew Removal Machine\u003C\/strong\u003E\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Ultrafast Fluid Ejection in Biological Systems: The Spotted Lanternfly as a Dual-Mechanism Honeydew Removal Machine"}],"uid":"27707","created_gmt":"2026-03-31 17:42:04","changed_gmt":"2026-03-31 17:42:35","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-04-03T15:00:00-04:00","event_time_end":"2026-04-03T16:00:00-04:00","event_time_end_last":"2026-04-03T16:00:00-04:00","gmt_time_start":"2026-04-03 19:00:00","gmt_time_end":"2026-04-03 20:00:00","gmt_time_end_last":"2026-04-03 20:00:00","rrule":null,"timezone":"America\/New_York"},"location":"MRDC Conference Room 4211","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
