Josh joined the Cai lab group in 2019 as a PhD student, shortly after graduating with a Biology MSci from the University of Bristol. His work involves using CRISPR and adeno-associated virus (AAV) to develop tools for rewriting human genomes. These will allow analysis of the functionalities of genetic sequences at a previously unattained resolution. This project is in collaboration with the Chew Lab (Genome Institute of Singapore). Outside of the lab, Josh enjoys travel, SCUBA diving and climbing.
