Trials Officer

My role is very varied and sees me working closely with lots of other teams here at Wisley in order to manage the trials effectively

I started working in the Wisley Trials Office in 2007 and, as a Trials Officer, I'm responsible for the project management of a range of trials from one to three years in length. 

I'm currently managing the following trials based at RHS Garden Wisley: blackberries and hybrid berries; dahlias; Digitalis; Euphorbia; and sweet peas. 

In addition, I look after an offsite Sarracenia trial. My role is very varied and sees me working closely with lots of other teams here at Wisley in order to manage the trials effectively.
