Computing

Within the computing press I write primarily about Macintosh software, ranging from in-depth reviews of big productivity applications like Microsoft Office and Freeway Pro through to shareware goodies and system add-ons. I also write tutorials and occasionally opinion pieces.

Fishkeeping

My articles in this field are mostly about freshwater community species and systems and aimed at beginner and intermediate-level aquarists. Topics covered include water chemistry, species selection, healthcare, troubleshooting and breeding. I also like to cover the so-called ‘oddball’ species frequently kept by more advanced aquarists such as pufferfish, rare livebearers, spiny eels and brackish water fish.

Geology

As a geologist my expertise is based firmly within palaeontology rather than hard rock geology; as such my articles tend to be about fossils, fossil collecting, and how scientists use evidence from the fossil record to advance our understanding of the natural world.

Astronomy

Deep sky observing, specifically galaxies visible from suburban locations.
