Ok, this is just a pubmed abstract but i found a few facts interesting. Big names with years of experience are copublishing a paper. And De Ridder is still lead author of a tinnitus paper while using his coordinates in New Zealand. Means he hasn't totally left the ship. In fact i recall an interview where he said he could devote much more of his times to research after he moved.
