In the eyes of every author, I fancy, his past work falls into four classes. First, the pure rubbish which he regrets ever having conceived; second — for him the most painful — the good ideas which his incompetence or impatience prevented from coming to much... third, the pieces he had nothing against except their lack of importance; these must inevitably form the bulk of any collection since, were he to limit it to the fourth class alone, to those poems for which he is honestly grateful, his volume would be too depressingly slim.
— W. H. Auden, preface to The Collected Poetry of W. H. Auden (1945).

It's all fake bs to make you think they're really clever.

Below is an approximately up-to-date list of papers and other articles which I've been involved in writing. If you believe in citation records and the associated metrics, you may find mine on ResearcherID and on Google Scholar. My ORCID profile number is 0000-0002-9235-7052. I do not record peer reviews via Publons, so any nonsense they publish about my peer-review record is entirely fictional.

Where possible, I've provided a link to the DOI (digital object identifier) of the paper: this will take you to a summary of the paper on the publishers' website, from which you may be able to download the paper itself. Where a paper is marked "Open Access" you should be able to download it from the publisher for free; in some other cases I've provided a link to a preprint on the University's repository.

Popular and expository pieces

As well as curating the unofficial department blog, I've written a fair number of articles for it. They tend to be at most loosely associated with my research interests, which may be why they're fun to write. Here are a few that I think have more interesting content than the rest.

Also listed here, because I can't think of a better place for it, is my sole and extremely self-indulgent foray into local history: The loss of the Vivid: the biography of a shipwreck. It's probably the definitive account of the sinking in 1913 of the Royal Technical College's training ship less than a day into her first cruise, if only because I don't think anybody else has bothered to write one. A brief outline of the story, with an emphasis on the Helensburgh connections, can be found on the excellent Helensburgh Heritage website.

My PhD thesis

My PhD thesis is no longer available in full online, but if you're curious you can have a look at the Abstract or the Introduction. (Be warned: the abstract is ridiculously short in order to comply with some daft rules made up by a form-filler who's never had to summarize three hundred pages of maths in under 300 words, while the introduction was written very late at night and possibly says more about the effects of CafeDirect Rich Roast than it does about the thesis. You might find it interesting anyway.)
