PhD student

I am utterly passionate about discovering and refining molecules from nature for specific applications and this is reflected in my PhD research focusing on glycobiotechnology.

Previously, I have created technology to detect novel fluorescent proteins in coral reefs, conducted industrial-scale protein production, genetic engineering with an emphasis on cloning and expression and scientific business. I have been involved in international collaborations and worked across academia and industry, fulfilling contracts from philanthropists to governments.

Novel sugar compound discovery for industry

My work focuses on bioprospecting, biochemistry and the genetics of novel exopolysaccharides (EPS) from marine bacteria alongside my industrial partner.

There is a huge demand for novel EPS from the medical industry to replace and enhance existing products used in surgeries.

Marine bacteria often have unique structures and confer increased biocompatibility with humans compared to terrestrial bacteria, making the ocean a gold mine for novelty.

Using a range of techniques, including microbiological, GC-FID, cloning, expression and rheological, amongst others, the goal is to develop a toolbox of novel polysaccharides for use within the surgical field and to understand the requirements for synthetic carbohydrate chemistry.
