I have worked at Enviresearch since graduating from my PhD studies in 2003. My role within the company is to perform standard and higher tier environmental risk assessments to support pesticide registrations. Computer modelling forms a central part of my day-to-day work, and I am familiar with the use of pesticide fate models both within the FOCUS framework and in the context of individual member state requirements. I lead the technical editing services offered by Enviresearch and am involved in preparing and delivering training to clients.
