OUTREACH ACTIVITY 1 This outreach event will be coordinated by NUID UCD, and ESRs from our consortium will be in charge of running this outreach programme in their respective organisation. Public: Secondary school 15-year-old pupils from socio-economic disadvantaged backgrounds associated with low progression to third level education. Countries: France, Belgium, Italy and Ireland. Event: 1 day event, in October/November taking place simultaneously in different EU Partners countries once a year, for four years. Delivery: o One week prior our event, participants will answer questionnaire about HIV/AIDS-related issues. o On the day (morning), following a brief Skype session to introduce pupils from each country, classes and their teachers will meet with professional (consultant, nurse, researcher) and HIV positive individuals and patients advocates in question/answer sessions to facilitate their understanding of this infectious disease, its transmission, current treatments efficacity and limitations, and the na
Establish thematic WorkshopsWe will exploit workshops as a tool to transfer of knowledge and know-how of our consortium core research disciplinary skills and expertise. These will be organized during the month of July every year as consortium members will have less commitments. These four-days workshops and their associated themes are listed below • Dissecting the Host-virus interface with system-wide screening approach. Month 8, NUID UCD, Dublin, Ireland. • State of the Art tools for HIV Cure Research. Month 20, Saint Pierre Hospital, Brussels, Belgium. • Epigenetic control of HIV post-integration latency. Month 32, University of Strasbourg, France. Speakers from the consortium will provide expert overviews of their fields, followed by in-depth discussions of their own work. Importantly, secondees will be invited to share their acquired knowledge and experience, with a critical view, as they will beneficiate from expertise from their home-institution and the newly acquired ones. ESR and ER will be invited to submit abstracts an
Implementation of Secondments across the EU4HIVCURE consortiumThe embedded nature of our secondments , which are at the core of our collaborative strategy, will enable us to go beyond the simple association of a clinician with a biomedical researcher. Indeed, the role of the secondee is not only to learn and implement a given technique or experimental approach but to act as the catalyst of the collaboration. Implementation: In order to ensure that the quality of knowledge sharing is maintained at the highest possible level, a number of specific measures will be undertaken: Explicit agreements will be drawn in advance of the secondments, to document the learning and research objectives, to highlight the interdependence, joint ownership, and collective responsibility for the secondment and research project. In addition they will include publication authorships, IPs, Patents and/or non-disclosure agreements. Principal Ivestigators (PI’s) from all consortium members are committed to provide an environment favorable to knowledge transfer and to maximise the outputs of the
Close-out Meeting, organised by ICGEB will take at M46 place in their facility in Trieste, Italy. During our final meeting hosted by ICGEB in Italy, time will be allocated to produce video seminars given by our EU4HIVCURE consortium members on HIV CURE Research. We will benefits from ICGEB facilities to record and edit these video seminars, which will be broadcasted using ICGEB’s own channel on iTunesU.
