Josh Van Dongen

Josh Van Dongen

Doctoral Researcher

More about Josh...

Josh is part of the technical team working in the laboratory to produce our Cellusphere surfactant. Initially joining as a Summer assistant at the end of 2023, he started learning the ins and outs of the Cellusphere process, he has since continued to help optimise our procedures and solve any problems we run into as a team. He is responsible for producing Spherelose, contributing at all parts of the process.

Josh has a BSc in Chemistry and Geoscience from AUT and has started studying towards his BSc (Honours). His Honours research project will incorporate our Cellusphere technology and investigate how stimuli-responsive materials can be introduced to our particles to turn them into stimuli-responsive surfactants. 

In his spare time, Josh enjoys all things sports and science along with spending time with family. He loves to get out and about to explore nature and his photography skills but also enjoys his time at home listening to all types of music and watching anything non-fiction. He’s also an avid cat and dog lover!
