Everyone is born a scientist. I've always thought that. Children are full of
curiosity: I never made a conscious decision to become a scientist, but at school
it was science that seemed to ask the questions I was interested in. I realised
a career in science would never be boring, and that's how it has turned out.
I got a degree in biochemistry and have worked in molecular biology ever since.
I still run a research lab one day a week - that's important for my role as Chief
Scientific Adviser because it gives me credibility in the broad scientific community
I try to represent.
I work on microbial diversity in the environment. The work took a huge step forward
a few years ago when a research student and I were in Portugal and went swimming
in the sea at night. She emerged shimmering with light, and we suddenly realised
we could make the microbes we worked with
bioluminescent. We modify bacteria in the lab, and use the glow to track where they are and
monitor how happy they are. If there is pollution, the lights go out. We commercialised
that knowledge, which was a new experience for me. We now apply the same technology
to other areas of research such as human health.
I became involved in strategic work when I was appointed to the governing body
of the
Natural Environment Research Council, which has a very large research budget. It was a big insight. I thought it
might be a chore, deciding on priorities and expenditure. Instead, I found it
incredibly stimulating. And I was meeting and working with talented people from
a much wider range of backgrounds than I usually met through work.
So I've sat on various committees and taken on extra roles such as lecturing
for the
UK Research Councils and being a judge on their
Business Plan Competition. I do a lot of mentoring as well - men and women. The men surprise me because
they go for things that are several rungs higher up the ladder. They are more
confident, more aspirational. My advice to women is always be bold - appreciate
your worth, don't wait for others to suggest you do something, and don't let fear
of rejection set you back.
I became Scotland's first Chief Scientific Adviser in 2006, through application
and interview. I co-ordinate science evidence and advice across the Scottish Government,
and make sure politicians and staff are connected to live science issues. There
are challenges like climate change that many departments have to address and where
I can make a significant contribution. Outside government, I try to promote science
as a career choice. I do a lot of public speaking and media interviews, and I
liaise with business. I promote Scotland as a science nation. The work means I
travel a lot.
Its another opportunity to raise important issues, including providing flexible,
family-friendly working environments. What matters is quality and efficiency,
not long hours. Government must take a responsibility here - its hard for small
businesses to carry all the costs. But we are losing talented people in whom we've
invested a lot. I hate to see waste like that.

I'm pleased to be a role model. I hope women see me in my role as Chief Scientific
Adviser and think 'a woman's doing that job, so I could do it too'. Finally, I
thought I'd use a photo of me sailing - without a work-life balance, none of this
would light up for me.
