I grew up in Sunnyvale, California, in the heart of Silicon Valley, raised by two computer geeks and surrounded by many more. This was my first portable computer, made by the company my mom worked for.

My father is from Norway, so my surname is pronounced like “Lawrencen,” with the accent on the first syllable, not with the accent on the second syllable, like “Lorenzo.” Had my father not gotten enmeshed in the world of computing and moved to the US, I would probably be a grocer. My sister was a physicist who studied the aurora.  Female physics undergrads should apply to the scholarship established in her memory.

I am a proud product of California’s public education system, a graduate of Wilcox High School in Santa Clara.  After high school I lived in China, Hong Kong, and Taiwan for several years, including two in an old house behind this building in what was once Shanghai’s French Concession. I have also lived in London, New Hampshire, and Palo Alto.

Currently I live in San Francisco’s under-appreciated Glen Park neighborhood with my wife and sons.  One of them, Milo, has a very rare (as yet unnamed) congenital disorder. You can read more about him here.
