“Working at Thomson has furthered my passion for marine biology. By completing benthic surveys and identifying the collected taxa, I know I am contributing to how our marine environment is monitored and used. I especially love having the opportunity to see rarely recorded benthos from our exciting deep-sea projects. Being given training and support from my colleagues, who are highly regarded marine taxonomists, I have been able to develop my taxonomy knowledge and progress in the company. I’m grateful to work along such a fantastic bunch of people and I have formed lasting friendships here, both through working closely with my team on survey and in the lab, as well as on our trips to the pub.” – Joanna G

“My time working at Thomson has been thoroughly enjoyable, the whole team were very welcoming and friendly from the start and I’ve made some great friends here. My taxonomic knowledge has massively improved since I started thanks to the training and support I’ve received from the other staff. Working here has given me opportunities to work with fauna from all over the UK as well as some really exciting deep sea projects from Scotland and Africa. It’s been great working in a positive, friendly environment while developing professionally.” – Dale I
