Dr Nathaniel Clark

Post-Doctoral Research Fellow

Weekend Technician for Fish and Rodent Facilities

Qualifications

BSc. (Hons) Marine Biology and Oceanography

MRes. Marine Biology

Ph.D. in Toxicology (2019). My thesis had three aims:

1. Investigate the dietary bioavailability and bioaccumulation of nanomaterials in fish using ex vivo and in vivo experiments.

2. Development of a suitable extraction protocol for nano silver from tissues, with subsequent quantification using single particle ICP-MS. 

3. An assessment of the bioavailability of nano silver to the mammalian gut.
