At Harvard, Carrie Grimes majored in anthropology and
archaeology and ventured to places like Honduras, where she
studied Mayan settlement patterns by mapping where artifacts were
found. But she was drawn to what she calls “all the computer and
math stuff” that was part of the job.
Carrie Grimes, senior staff engineer at Google, uses statistical
analysis of data to help improve the company's search engine.
“People think of field archaeology as Indiana Jones, but much of
what you really do is data analysis,” she said. She uses statistical
analysis of mounds of data to come up with ways to improve its
search engine.

Ms. Grimes is an Internet-age statistician, one of many who are
changing the image of the profession as a place for dronish number
nerds. They are finding themselves increasingly in demand — and
even cool.

“I keep saying that the sexy job in the next 10 years will be
statisticians,” said Hal Varian, chief economist at Google. “And I’m
not kidding.”
The rising stature of statisticians, who can earn $125,000 at
top companies in their first year after getting a doctorate, is a
byproduct of the recent explosion of digital data

In field after field, computing and the Web are creating new
realms of data to explore — sensor signals, surveillance tapes,
social network chatter, public records and more. And the digital
data surge only promises to accelerate, rising fivefold by 2012,
according to a projection by IDC, a research firm.

The new breed of statisticians tackle these problem. They use
powerful computers and sophisticated mathematical models to hunt
for meaningful patterns and insights in vast troves of data. The
applications are as diverse as improving Internet search and online
advertising, culling gene sequencing information for cancer
research and analyzing sensor and location data to optimize the
handling of food shipments.
