Outline of the outline lecture

Bioinformatics as hypothesis generator for
biomedical research in the postgenomic era
 Bioinformatics at the University of Cincinnati
& Children’s Hospital Research Foundation:
research and resources
 Introduction to Bioinformatics course:
problems and case studies, web and Protein
Modeling Lab resources, syllabus and some
practical issues
JM - http://folding.chmcc.org
2
Bioinformatics as hypotheses generator
Making sense of massive amounts of genomic,
proteomic etc. information in order to facilitate
further experiments by data mining and
inference, modeling and computer simulations.

Some more “precise” definitions
“Roughly, bioinformatics describes any use of
computers to handle biological information”
 “In practice the definition used by most people is
narrower; bioinformatics to them is a synonym for
"computational molecular biology“ -- the use of
computers to characterize the molecular components
of living things.”
 “The mathematical, statistical and computing methods
that aim to solve biological problems using DNA and
amino acid sequences and related information.”

Other “definitions”




Subject or body of research – e.g. google
bioinformatics and simply digest the 2 ML (1 ML= 106
Links) or so …
Methods and approaches: computational paradigm in
molecular biology and biomedical research
Institutional boundaries – take a body of research
from all the scientific institutions having
“bioinformatics” in their name
Let us have look at local bioinformatics resources
