If possible all PIs and PhD students should participate at the round table discussions. This event should give the possibility to discuss PhD projects, specific data, problems or methods in small groups of PIs and PhD students. We will set up 5-6 discussion groups. For the online edition of our B Cell Winter School we would like to have the doctoral students work on certain research questions during the round table discussion e.g. „How to isolate Ag-specific plasma cells for the fast production of neutralizing antibodies." We would appreciate it very much if you have further suggestions.
