Владивосток, Россия, 24 мая 2017 г. с 13:00 до 17:00
Место проведения – Приморский океанариум
Анонс мероприятия
В рамках школы молодых ученых будут проведены лекции и практические занятия на тему молекулярных методов обнаружения токсичных видов микроводорослей с помощью ДНК-хромотографического чипа.
Школу будет проводить ведущий мировой специалист в данной области Доктор Сатоши Нагаи (Prof. Satoshi Nagai), возглавляющий Группу геномики окружающей среды в Национальном научно-исследовательском институте рыбного хозяйства (Иокогама, Япония). В настоящее время он занимается внедрением метагеномного подхода в рутинный мониторинг состава морских микроогранизмов.
Также в составе исследовательских групп С. Нагаи стал известен следующими разработками: молекулярное обнаружение бактерий при пищевых отравлениях, ДНК-ДНК гибридизация для морских бактерий, молекулярное обнаружение и количественное определение токсичных динофлагеллят, еиспользования высокополиморфных генетических маркеров и анализ генетических структур для токсических динофлагеллят.
Сбор студентов и молодых ученых, желающих принять участие в работе школы состоится 24 мая 2017 г. в 12:30, ДВФУ, корпус В.
Доставка участников в Приморский океанариум будет осуществлена автобусом ДВФУ (табличка «Школа молодых ученых – 2017»).
Рабочий язык школы английский.
Dr. Satoshi Nagai
Dr. Satoshi Nagai is working for Japan Fisheries Research and Education Agency, National Reserch Institute of Fisheries Science, Research Center for Bioinformatics and Biosciences as a group lead at the Environmental genomics group. Recently, he has focused on metagenomic approach to introduce this technology to routine monitoring. He has participated a lot of metagenome projects to study not only the biodiversity of marine eukaryote and bacteria, but also feeding habits of sardines, eels, and abalones. He also has collaborated about this with many research institutes oversea, such as Finland, Bulgaria, Singapore, Chile, Australia and Russia.
