Felix Bubeck successfully defended his PhD entitled: “Searching the hairpin in the haystack: Engineering the replication origin of AAV vectors” researching the use of synthetic AAV ITRs for enhanced vector persistence. Felix completed his PhD at the Heidelberg University, Germany and is pictured with his PhD supervisor and fellow ARDAT colleague Professor Dirk Grimm wearing his “PhD hat” depicting two ITR’s protruding from the hat. Congratulations Felix!
