Tsukruk received his MS degree in physics from the National University of Ukraine, PhD in polymers and DSc in chemistry and polymer science from the National Academy of Sciences of Ukraine. He carried out his post-doc research at the U. Marburg, Darmstadt TU, and U. Akron. He is currently a Professor at the School of Materials Science and Engineering, Georgia Institute of Technology and a Director of Microanalysis Center. He serves on the editorial advisory boards of seven professional journals, has co-authored around 390 refereed articles in archival journals, as well as five books, has organized ten professional symposia, and trained about 60 students and post-docs. His research in the field of surfaces, interfaces, and molecular assembly of synthetic and natural polymers, nano- and bioinspired hybrid nanomaterials has been recognized by the Humboldt Research Award (2009) and the NSF Special Creativity Award (2006), among others. He was elected as an APS Fellow in 2010, a MRS Fellow in 2011, and an ACS Fellow in 2014. His recent book (V. V. Tsukruk, S. Singamaneni: \u003Cem\u003EScanning Probe Microscopy of Soft Matter: Fundamentals and Practices\u003C\/em\u003E, Wiley, 2012) is a popular comprehensive textbook on SPM applications of synthetic and biological materials.\u003Cstrong\u003E\u003Cbr \/\u003E\u003C\/strong\u003E\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Please join us as we welcome Professor Vladimir Tsukruk of the School of Materials Science and Engineering at the Georgia Institute of Technology."}],"uid":"27863","created_gmt":"2014-10-31 13:34:24","changed_gmt":"2017-04-13 21:21:17","author":"Christa Ernst","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2015-03-10T13:00:00-04:00","event_time_end":"2015-03-10T14:00:00-04:00","event_time_end_last":"2015-03-10T14:00:00-04:00","gmt_time_start":"2015-03-10 17:00:00","gmt_time_end":"2015-03-10 18:00:00","gmt_time_end_last":"2015-03-10 18:00:00","rrule":null,"timezone":"America\/New_York"},"extras":["free_food"],"hg_media":{"366561":{"id":"366561","type":"image","title":"Tsukruk","body":null,"created":"1449245817","gmt_created":"2015-12-04 16:16:57","changed":"1475895103","gmt_changed":"2016-10-08 02:51:43","alt":"Tsukruk","file":{"fid":"201702","name":"tsukruk_bio_2015.jpg","image_path":"\/sites\/default\/files\/images\/tsukruk_bio_2015_0.jpg","image_full_path":"http:\/\/tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/tsukruk_bio_2015_0.jpg","mime":"image\/jpeg","size":23199,"path_740":"http:\/\/tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/tsukruk_bio_2015_0.jpg?itok=SQzD0Mf3"}}},"media_ids":["366561"],"groups":[{"id":"1271","name":"NanoTECH"},{"id":"197261","name":"Institute for Electronics and Nanotechnology"},{"id":"198081","name":"Georgia Electronic Design Center (GEDC)"},{"id":"213771","name":"The Center for MEMS and Microsystems Technologies"},{"id":"213791","name":"3D Systems Packaging Research Center"}],"categories":[],"keywords":[{"id":"115341","name":"bioelectronics"},{"id":"10677","name":"biosensing"},{"id":"12701","name":"Institute for Electronics and Nanotechnology"},{"id":"66381","name":"Nano@Tech; nanotechnolgy"},{"id":"1785","name":"nanomaterials"},{"id":"8239","name":"Vladimir Tsukruk"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78751","name":"Undergraduate students"},{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003E\u003Ca href=\u0022mailto:david.gottfried@ien.gatech.edu\u0022\u003Edavid.gottfried@ien.gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
