As of today, a new face has joined the team of Development editors, and a familiar one is soon to be leaving us. After 6 very successful years at the journal, Ken Zaret has decided to step down: we will miss him, but we’re sure the extra time he’ll have will be put to great use – both for his research and his other activities. Replacing Ken, and complementing particularly his expertise in epigenetics, we are delighted to have recruited Professor Haruhiko Koseki to the Development editorial team. Haruhiko is Group Director at the RIKEN Center for Allergy and Immunology in Yokohama, Japan. His lab is interested in understanding the molecular basis of epigenetic inheritance, and its consequences on haematopoiesis, stem cell identity and various other aspects of development. We’re excited to have Haruhiko on board, and we wish him luck for his first days and weeks in his new job!
