HAL's Curriculum Vitae
Bioinformatics is a new subject of genetic data collection,
analysis and dissemination to the research community.
Since the coining of the word "bioinformatics" (See also
Bioinformation and Rise of Bioinformatics ;
Turbocharging Bioinformation)
and the convening of the first international conference on
the subject by HAL in the late 1980s, bioinformatics has undergone several
stages of rebirths. In certain respects, the definition overlaps with that of
computational biology and bioinformation infrastructure. In
general, bioinformatics, computational biology, and ancillary
computer supports (e.g., networking, hypertext, etc) taken together cover the
whole spectrum of use of computers in biology-related sciences. There is really
no sharp division between the two. However, there are two common distinctive
features of bioinformatics and computational biology:
Even though the three terms: bioinformatics,
computational biology and bioinformation infrastructure are often
times used interchangeably, broadly, the three may be defined as follows:
Thus, the latter may be viewed as a computational scaffold of the former two.
Since its humble beginning, the definition for bioinformatics has metamorphosized from the original and in many ways, naive, definition of data collection, analysis and dissemination to a current more encompassing definition. Its domain of application has also widened from being a special niche tool to that of an essential corporate technology. The scope has widened from a laboratory-based tool to an integrated corporate infrastructure.
Bioinformatics is currently defined as the study of
information content and information flow in biological systems and processes. It
has evolved to serve as the bridge between observations (data) in diverse
biologically-related disciplines and the derivations of understanding
(information) about how the systems or processes function, and subsequently the
application (knowledge). A more pragmatic definition in the case of diseases is
the understanding of dysfunction (diagnostics) and the subsequent applications
of the knowledge for therapeutics and prognosis.
Bioinformatics has become a mainstay of genomics, proteomics, and all other *.omics (such as phenomics) that many information technology companies have entered the business or are considering entering the business (see Computer Giants invest in Bioinformatics world), creating an IT (information technology) and BT (biotechnology) convergence. Because of this unprecedented phenomenon, HAL is regularly approached by consultants who are evaluating the market for companies considering entering the bioinformatics sector.
In almost all discussions and interviews, it became extremely
clear that a distinction has to be made between a bioinformaticist and a
bioinformatician.
A bioinformaticist is an expert who not only knows how to
use bioinformatics tools, but also knows how to write interfaces for effective
use of the tools.
A bioinformatician, on the other hand, is a trained
individual who only knows to use bioinformatics tools without a deeper
understanding.
Thus, a bioinformaticist is to *.omics as a mechanical
engineer is to an automobile. A bioinformatician is to *.omics as a technician
is to an automobile.
It has been argued that the professional categorization of bioinformatician and bioinformaticist may lead to some confusion. It is undeniable this may be the case. For example, a mathematician is an expert. However, we note that a physicist is an expert, so is a physician, except that they are in very different professions.
An issue that regularly pops up is the definition of bioinformatics, particularly from individuals who are trying to get into the field. Most lament that there are too many definitions of bioinformatics.
This should be taken as an indication of the ubiquity of the subject. Bioinformatics, as both an enabling and enabled technology, will be defined differently depending on the domain of the person who is giving the definition. A computer scientist will give one definition, a biologist another, a biotechnologist yet another, and an individual from a pharmaceutical company will provide yet another definition.
Each definition is as good as the other. This is just the nature of the beast.
An important point to note is that bioinformatics is an enabling and an enabled tool, as such it will never replace the bench work and wet lab experiments of the biological, biochemical, health and clinical sciences. It only helps the areas it is being applied
Thus it would be unwise, particularly for bioinformaticists, to just write the best computer programs, or to just integrate the most sophisticated integrated packages to churn out numbers and beautiful graphics. The bottom line is still the biology, the biochemsitry, the healthcare system. Nothing, not the best software, nor the most sophisticated package, can replace real life systems.
