Systems Genomics Summit 2021 is organized by a committee of PhD students from five Irish universities (NUIG, RCSI, TCD, UCC and UCD). We are supported by the PhD programs in SFI Center for Research Training in Genomics Data Science and the UCD Bioinformatics. Having all started our PhDs mid-pandemic, we look forward to welcoming you to a fantastic event online this February! We are Rasha Shraim (TCD), Shane Crinion (NUIG), Cosmin Tudose (UCD), Tembi Fashina (RCSI), Padraic Heneghan (UCD), Donal O'Shea (NUIG), Anjan Venkatesh (UCD), Marina Villacampa Fernandez (UCD), and Sai Ravi Chandra Nori (UCC).
