Why experts are calling data
science the sexiest job in the world
It’s not often that an occupation is
crowned “sexiest job of the century” only
a few years after it pops up. But data
scientists have bucked the trend and are
reigning supreme in the job market –
and they’re reaping some impressive
benets as a result.
Procient at navigating vast oceans of
information to sh out hidden trends and
patterns, data scientists are at the
forefront of computer science and
articial intelligence. They develop
software and algorithms to target the
information they’re seeking and then,
from that mind-numbingly massive
coalface of big data, they extract
invaluable insights for their clients.
Now, less than a decade since LinkedIn
and Facebook analysts popularised the
term “data scientist”, it’s become one of
the most coveted roles for ambitious,
tech-savvy individuals, with some of the
world’s most successful companies like
Google and Walmart scrambling to snap
them up.
And that’s why back in 2012, the
esteemed Harvard Business Review
bestowed the title of “Sexiest job of the
21st century” on data scientists.
“Think of him or her as a hybrid of data
hacker, analyst, communicator, and
trusted adviser,” write The Review’s
Thomas H. Davenport and D.J. Patil.
“The combination is extremely powerful
– and rare.”
Leading a healthcare revolution
In the healthcare sector, data scientists
are now coming into their own -
particularly with the recent opening of
UNSW’s world-leading Centre for Big
Data Research in Health.
Using large-scale electronic data that
spans the biomedical, clinical and
health services domains, the Centre
brings together more than 60 research
staff and students to tackle critical
health issues facing Australian and
global communities.
“I love it because it’s so stimulating,”
says Professor Sallie-Anne Pearson,
head of the Centre’s Medicines Policy
Research Unit, which uses big data to
determine how medicines are being
used locally and internationally.
“It’s science, but there’s a lot of art in
this.”
Data scientists in the health sector can’t
rely on their technical skill alone, says
Peter Cronin, co-founder and managing
director of Prospection, a Sydney-
based health insights company. They
also need people skills, communication
skills, and an inquiring mind.
“Being a good data scientist in this
sector means rst being able to
understand what is the question that
someone wants to ask. Then you need
to understand the data you’re working
with, including the limitations of that
data,” Cronin explains.
Big data scientists are entering the world of
healthcare, and the impact is set to be revolutionary.

“Thirdly, you have to be able to develop
algorithms. And the fourth component
is knowing how to communicate or
visualise the answer to be able to
present it to the client.”
“Within healthcare there are a lot of
nuances to the data, and healthcare
can be complex,” he says. “It really
helps to understand disease and that
sort of thing.”
Centre researcher Associate Professor
Georgina Chambers of the National
Perinatal Epidemiology and Statistics
Unit says the exponentially growing
area of big data in health is enthralling,
but it’s in desperate need of more data
scientists to grapple with the issues
that come from accessing such data.
“I’m excited by it, but what I sense is
that, like a lot of medical science, the
science is going to move a lot faster
than individuals’ and society’s ability to
digest it,” she says.
And because data science is cross-
disciplinary, Pearson adds, there are
opportunities for everyone.
“What I love about this eld is it’s so
diverse,” she says. “I’m a behavioural
scientist – I’m not a doctor, I’m not a
pharmacist. But I’ve been able to
establish a research career. Data
science welcomes everyone.”
