Mark Andersen makes stuff up. Fortunately for everyone who knows him, he restricts his fancy to writing fiction. He's the author of a contemporary fantasy series, Merlin's Thread.
He started writing professionally in 1999. For eleven years, he wrote science articles for Oilfield Review; for nine of those years he was the journal's executive editor. Sadly, he couldn't make things up during that part of his writing career. He has a PhD in physics from the Johns Hopkins University and worked in the oil industry for thirty-four years as a research scientist, domain expert, and writer. Now, Mark writes full time. No, really ... he wouldn't make that up.
