Vadim Kuznetsov studied and graduated in Leningrad (now St. Petersburg). In 1993 he came to Amsterdam for a two-year postdoc position with me. After further postdoc positions in Denmark and Canada he settled in Leeds, first in temporary positions obtained by successful grant applications, and eventually in a tenured position as a Reader in Applied Analysis.
Vadim was always very kind and enthusiastic. He had 21 coauthors. He was
very active in organizing meetings, of which two Proceedings edited by him
have appeared. A third volume, the
Proceedings of the Workshop on Jack,
Hall-Littlewood and Macdonald polynomials (Edinburgh, 23-26 September
2003), coedited with Siddharta Sahi, has appeared in 2006 in the AMS
series Contemporary Mathematics.
Vadim is survived by his wife, Olga, and son, Simon.
