My interests are tapping into the gold mine of novel compounds in the ocean. These can be used for medicine to making clothes and I am thus very much an applied scientist dedicated to delivering science that has quick and long-lasting impacts.

I am motivated by finding and filling gaps in the market and enhancing products that already exist.

During past jobs, I have completed work in genetic engineering, industrial protein production and scientific business. I have worked with and for individuals, companies and governments with products and my research being utilised and presented across four continents.

Novel sugar compound discovery for industry

There is huge demand for new sugar compounds from industry, including biomedicine, oil, textiles, food and cosmetics. Discovering such compounds is, therefore, highly important.

Marine bacteria are excellent producers of these compounds and as the marine environment is the least explored ecosystem, it presents a gold mine for discovery.

I focus on discovering and refining these compounds for application within industry; taking a bacterial sample from the marine environment to application.

Initially I look for tell-tale signs of industrially relevant compounds based on their physical characteristics (stickiness, gloopiness, stringiness). Each application requires a very different compound, thus I make an assessment for each.

I then look for novelty through assessing the DNA of relevant bacteria, identifying parts of DNA that make them likely to produce novel, industrially relevant compounds. I further back up this assessment using fancy equipment that can tell me what the compound is made of.

My aims are to expand the amount of industrially relevant compounds available on the market, further the understanding of the DNA used to create these compounds and work out how I can genetically engineer bacteria to produce tailor-made sugar compounds.
