I joined Puzzler in 2006 as editor of the recently launched Sudoku magazine – a magazine dedicated to a new and unusual number-logic puzzle. I also edit Killer Sudoku, Kakuro, Fundoku, Sudoku Puzzles and foreign-language versions of these and other sudoku related publications.

When not scratching my head over a sudoku, I can be found curled up in front of my fire, reading a good book or watching a DVD. I'm a devotee of Ashtanga Yoga; love skiing, travelling and four-wheel driving; and I have recently taken up bouldering – clinging to a rock by your fingertips: it gives you a sense of proportion.
