Science as a career
Science as a Career
Interesting
Use your brain
Continue learning
Discover the unknown, and pursue it
Expert in your field
Freedom of research
Flexible work
Variety within work
Active
Not a traditional job for life
You can travel with jobs
You can travel with conferences
South Africa - Kruger
Zimbabwe – Victoria Falls
South Africa – Cape Town
Puerto Rico
Young and varied people
- casual
Further personal development
You don’t do it for the money
Science has geeks
But other professions have issues too
Career structure in science
Career Structure in Science(not that you have to decide early on)
Postdoctoral position
Undergraduatedegree
Ph.D.Lectureship
(Professorship)
Second postdoc...
Undergraduate degree
– Natural Sciences for choice of subjects•First year: cell biology, physiology, chemistry, maths
•Second year: molecular cell biology, biochemistry,
history and philosophy of science•Third year: Genetics
– Can lead to a number of careers
– Need 2.1 or above for PhD
– Format: lectures and practicals
Ph.D.
– Format: research (papers and lab work)– Choose a subject you are interested in– Autonomy : planning– Social life, sport, teaching ... – Produce a MAJOR piece of work (STRESS!!)– Useful skills for other jobs
Postdoctoral position
– Continue in same field or choose to learn another
–Location, location, location
–2-3 years to do publishable research
Second postdoc...
– Ditto– And maybe ditto again– Find your own niche / area of interest– Or move into industrial science
Lectureship
– Own research group
and teaching– Permanent post– More permanent location– Fewer women
(Professorship)
– Highest level in academia– Head of Department
My Ph.D. Project:Microbial Degradation of RDX
Bacteria eating explosives
Explosives are dangerous...
...to our
health
Explosive polluted sites
Explosives in bombs

RDXRoyal demolition explosive
Seeing bacteria eating explosives
RDX makes the
agar on the plate
look white and
grainy
Where RDX has been eaten and removed, agar is clear

The gene I discovered
Gene..... makes... Protein
Gene in plants
Normal, wild type plants - get sicker as they are grown with more explosive
Plants with my gene in - healthy when grown with explosive
more explosive in the soil

Comparing bacteria
Nice bacterium
Nasty, infectious bacterium Very similar to nice bacterium What are the differences? Can the genes tell us about infection?
Name a bug after yourself!
