Biografie (Dawn Griffiths)

Dawn Griffiths started life as a mathematician at a top UK university. She was awarded a First-Class Honours degree in Mathematics, but she turned down a PhD scholarship studying particularly rare breeds of differential equations when she realized people would stop talking to her at parties. Instead she pursued a career in software development, and she currently combines IT consultancy with writing and mathematics.§§When Dawn's not working on Head First books, you'll find her honing her Tai Chi skills, making bobbin lace or cooking. She hasn't yet mastered the art of doing all three at the same time. She also enjoys traveling and spending time with her lovely husband David.
