Jonathan Kerr has resurfaced!
He's working at Nuffield Health's Exeter Hospital, a small (47 bed) hospital in Devon. He is one of 3 haematologists employed there. The other 2 work there part-time.
That sounds like a huge come-down, in the sense that he's moved from a highly prestigious appointment at a prestigious London hospital, where he ran his own lab, to a dead end job in regional oblivion. Before this move, he'd spent more than 20 years climbing the career ladder. Maybe he likes the rural life, or has family reasons to be there; but it sounds like his decision to work on ME/CFS ruined his career.
