Magdalena Migalska defended her PhD entitled “MHC genes copy number and TCR repertoire size in the bank vole: diversity, selection and the optimal hypothesis”. The thesis was submitted as a collection of three peer-reviewed articles published in Heredity (link), Scientific Reports (link) and PNAS (link). She will next come back to her beloved Krakow, to continue work on MHC genes at the Jagiellonian University. We feel that Krakow is so lucky to have her and we will certainly miss her in the lab. Congratulations Magda!
