Viologens

Paul M. S. Monk received his PhD in the electrochemistry of novel electrochromic viologen species at Exeter University in 1989. A postdoctoral research fellow position (1989-91) at the University of Aberdeen, in Scotland, was followed by lecturing positions in Physical Chemistry at Manchester Polytechnic (1991-2) then Manchester Metropolitan University (1992-2007). He is currently employed as a Vicar in an inner-city parish in Oldham, Greater Manchester, UK.
