Dr David Eccles completed his postgraduate degree in biomedical science at Victoria University of Wellington in 2011. Dr Eccles is a Postdoctoral Research Fellow and Bioinformatics Research Analyst at The Malaghan Institute. He began his work at the Institute in late 2013 but also collaborates with various scientists around the world.
My main interest is exploring the biological code (DNA) that instructs our bodies how to work and how to respond to our environment. I am particularly fascinated by looking for patterns in DNA (or the absence of patterns), and investigating how those patterns describe organisms and influence biological systems.
The treasure and curse of bioinformatics is that almost every project opens up a new and unexpected area of research. I am excited by the discoveries we make, and have a constant battle with myself to clear my head of finished projects, and concentrate on new tasks and projects that await me.
I work as the glue between biologists and computers, helping with project design, data analysis and result presentation. I support researchers by using computer programs and can even develop custom software solutions for their projects. This work is usually called bioinformatics. It can speed up an analysis to be up to 5-10 times faster and allows researchers to explore existing data in more depth than previously possible. When the scientists I work with are no longer shackled to slow data processing, they are free to spend that time getting creative and expanding their research.
I’ve been a part of the Malaghan Institute for about four years now. The nature of my work means I am usually working on one-off and short term projects, lasting anywhere between a few minutes to a few months.
I work best when I have multiple projects on the go. My two “big” projects at present are looking at mitochondrial transfer in human cells and sequencing the genome of Nippostrongylus brasiliensis (a roundworm parasite important to many biomedical studies).
It is important that I participate in a diverse range of projects like this because I’ve often found that the same programs and methods can be used across quite different areas of research. It is common in science to almost start from scratch when a new project is conceived, but I liken that to collecting more haystacks in the search for needles. With specialised analysis, we can carry out research faster, cheaper and better and fully reap the benefits of our open and accessible research community.
