Courses biologists might consider taking:
- UNIX
-
Of all the computing courses available it is most important
that you have a proper introduction to the UNIX operating
system(s). Most current bioinformatics software (especially the
free stuff) runs on "open" platforms like Linux and the Web. The UNIX
philosophy is elegant, powerful, and frustrating. Master it and
you will save a lot of time.
- Mathematics
-
Learn some maths. Basic statistics, logic/set theory and a
little calculus would be my recommendation. Many practising
biologists have little or no grasp of elementary concepts like
statistical significance, permutations and combinations and the
principles of good experimental design. Logic will come in handy
at the very least if you want to query databases in an intelligent
way.
- Programming
-
If you're interested in development, learn a real programming
language: Pascal, C(++), Java or Fortran.
Perl and HTML are the stuff that holds the Web together. A
grasp of these is essential for a lot of the Web/database work
being done by many bioinformaticians at the moment.
Good old BASIC can be very useful as an introduction to
programming or as a tool in its own right, but none of these
latter languages is built to crunch numbers and tackle real world
biological problems---which isn't to say people don't try...
How can I get involved?---I am a
computational/quantitative scientist
One thing that I will emphasise repeatedly in this section is the
simple value of doing some "proper" biological laboratory science. I
have sat through many talks during which a bioinformatics
"scientist" describes in great detail how his---it's usually
"his"---application of a trendy mathematical tool offers a supposed
insight into a (sometimes supposed) biological problem. Nine times
out of ten I know that this method will never be so much as sneezed
on by a practising biologist.
Quantitative scientists sometimes talk about their interest in
studying some aspect of "God's mind". Biologists, in contrast, are
interested in "Mother Nature". You might meditate on God in the hope
of some revelation, but to understand Nature you have to meet her in
the flesh. You are as likely to be useful to biologists working in
isolation at the keyboard as you are to conceive with your clothes
on. Desk-bound bioinformaticians have written code that has
turned out to be popular with biologists, but almost always because
they have collaborated with biologists.
Courses quantitative scientists might consider taking:
- Molecular biology
-
"MoBi" was the bioinformatics of its day; desperately
fashionable, the province of new, higher-paid practitioners and
considered with slight suspicion by more traditional biologists.
It was once a great achievement to sequence a modest stretch of
DNA, now it's a job for robots. Today the technology of molecular
biology is very well established. Scientists can buy kits to
perform the sort of genetic manipulations that would make your
parents' jaws drop. Some of the kits are so simple your small
children could use them (with a modest amount of training and
supervision).
Despite the profusion of commercial kits, there is still a
requirement for real skill in molecular biology and the general
level of scientific understanding required to be a good biological
scientist---rather than just completing a practical
class---doesn't come easy. Living matter, the stuff you have to
work with is unpredictable and responds slowly---except when it's
dying. Even supposedly fast-growing bacteria can take a long time
to yield up their secrets.
Now, fashions in biomedical research are shifting from
molecular biology back to cell biology and protein biochemistry,
but it's well worth offering yourself up as a volunteer for some
vacation work in a molecular biology lab. The term is now more
often used to refer to the technological tools provided by MoBi to
biology in general, rather than to fundamental research in the
field itself. Those tools are common to a vast array of different
kinds of research, from archaeology to zoology.
