I have over 20 years' experience writing about science, technology and business, currently a freelance journalist and book author. My most recent book is "One Click: Jeff Bezos and the Rise of Amazon.com (Portfolio/Penguin, October 27, 2011.) It's the story of how Jeff Bezos got started, his impact on retailers, and what he's like as an entrepreneur and a manager (tough!) I'm also author of "Inside Larry and Sergey's Brain" (Portfolio/Penguin, 2009) which was released in paperback as "The Google Guys: Inside the Brilliant Minds of Larry Page and Sergey Brin." (Do you know how few people recognize the names "Larry and Sergey" without additional info? We found out.) I'm also co-author of "Capital Instincts: Life as an Entrepreneur, Financier and Athlete" (John Wiley & Sons, 2003.)

Having written two books in which the subjects would not give me interviews (interesting that the founder of a book-selling site does not give interviews for books) and one book in which the subject had too much control over the manuscript, my next book will be one in which I have direct access to the subject AND complete control over the content.

Not that it's impossible to write a biography without the cooperation of the subject -- it just takes a lot of research and interviews with people who know him or her well -- but I want to be able to really dig into the psyche of the subject. I'd like to ask Jeff Bezos, for example, why he never gives interviews any more unless he hits the talk shows with a product to sell, like a movie star hawking his new picture. I'd like to draw Larry and Sergey into a thoughtful discussion of privacy issues, their deep thoughts on the importance of Web search engines with honest results and how they maintain it.

Executives at public companies whose policies create controversy should get out into the world and explain themselves. They shape our society and affect our lives. I mean, come on! I've interviewed Bill Gates, Andy Grove, Michael Dell, Larry Ellison, scientists and top academics extensively over the years, and I don't do hatchet jobs.

Still, the book of which I'm most proud is "The Google Guys." I spent four years on it, off and on, most often on. One blogger claimed it was a hagiography, but that's just because I refuse to attack Larry and Sergey simply because that's a popular thing to do these days. I stand behind everything in the book. Most of the reviews were terrific.

Before the internet (temporarily) destroyed the business of journalism, I was editor-in-chief and columnist for technology/business magazine Upside from 1995 to 2001. From 1981 to 1995 I was a technology correspondent for Business Week Magazine. My freelance articles have appeared in CNBC.com, L'Express, Science magazine, Technology Review, Science/Business magazine, Stanford magazine and Working Woman. The Wall Street Journal did an excerpt of "One Click."

My awards include a National Magazine Award, Deadline Club Award; Washington Monthly Award; Atlantic Monthly Award; Computer Press Association Award; Acer/Boston Computer Museum Awards; I was a Knight Science and Technology Journalism Fellow at the Massachusetts Institute of Technology in 1991, and a Science Journalism Fellow from the American Association for the Advancement of Science in 1981. I've been a speaker on programs for BBC, CNN, NPR and industry events.

I studied engineering and journalism at the University of Delaware, received a BA in biology at the University of California, Santa Barbara, and studied mathematics at Harvey Mudd college.

I live in San Francisco with my wife and daughter, dog and two cats. My hobbies include carpentry, ocean kayaking, scuba diving, gardening and running. I re-roofed my own house.
