What is Computational Biology?

Computational molecular biology is conceptualizing

biology in terms of molecules & applying

“informatics” techniques - derived from disciplines

such as mathematics, computer science, and statistics -

to organize and understand information associated

with these molecules, on a large scale

(Gerstein, 2007)

Computational Approaches

Modeling regulatory networks

– Bayesian Networks

Inferring regulatory network models from

experimental data

– microarray data

– computation inference of module networks

Architectural properties of regulatory networks

– modular structure of regulatory networks

•Ask the right questions

•Select/Build the tools

•Learn more about the system and ask new questions

Ultimate goal : to understand all aspects of an

organism and its environment through the

combination of a variety of scientific fields.

Current Trends and Challenges

Overall trend: More people are recognizing that computer science can enable biological discovery

Prof. Stephanie Taylor, Colby College

Grand Challenge:Relating genotype to phenotype in complex environments (iPG2P)

GenotypeThe exact DNA sequence of an individual

PhenotypeThe collection of all observable and measurable traits of that individual

(Zhang et al. BMC Plant Biology 2008)(Wood et al. Science, 2001)

iPG2P:Multi-scale, Dynamic Problem

(ghr.nlm.nih.org; wikitextbook.co.uk; generalhorticulture.tamu.edu; scienceblogs.com)

iPG2P:Multi-scale, Dynamic Solutions

(ghr.nlm.nih.org; wikitextbook.co.uk; generalhorticulture.tamu.edu; scienceblogs.com)

Bioinformatics: learn from the data

Modeling: simulate the dynamical interactions among components

iPG2P:Cyber-infrastructure Challenges

Data management. Relating different data. Learning from the data.

1. Good middleware for virtual, integrated, distributed databases: Pipelining of NextGen sequence data into virtual genotype and molecular phenotype databases.

2. Data integration (adding depth and context to establish relationships and meaning) – relate information from such virtual databases to permit deeper insights, generation of hypotheses, evaluation of models, practical applications, etc

3. Statistically-based tools for use in inferring relationships. Many such tools exist, but the value-added aspect in the current context is to make them smoothly interoperable with the other features of the cyberinfrastructure.


Data and model visualization.

4. Visual analysis tools. It is necessary to present integrated data to users in ways that are both concise and revealing. This includes multi-dimensional data displays.


Modeling and model analysis.

5. Modeling framework tools to support the construction, parameter estimation, sensitivity analysis, and utilization of models. Again, the value added is in interoperablility.
