TESTIMONIALS
“As an editor and reporter, Mark Peplow is fast, accurate, and versatile. He covers science policy and pure research with equal passion, and his writing combines a scientist’s precision with a journalist’s verve.” Tim Appenzeller
Former Chief Magazine Editor at Nature, now News Editor at Science
"Mark guided me through some of the most challenging stories I've written. These are pieces I might not have attempted were it not for his steady editorial hand." Linda Nordling
Freelance Journalist, South Africa
“Working with Mark is never anything other than a pleasure. He is the kind of editor that writers hope for: able to identify what needs fixing and what doesn’t, bringing to bear a wealth of knowledge, always clear, prompt and easy to talk with. Much of that comes from being a splendid writer himself.”
