Tim is a plant pathologist with over 25 years practical experience
in microbiology and epidemiology and special interests in soil and
water borne plant pathogens as well as developing alternative
pest and disease control strategies.

Before joining NPARU, Tim worked at the Eden Project for 10 years looking at detection, diagnosis and troubleshooting disease problems in the Eden living collections as well as carrying out quarantine work and disease risk assessments on imported plant material. Prior to this, Tim led a research group at Horticulture Research International investigating and developing practical solutions to a wide range of plant disease problems and supporting their implementation in nurseries.
