Taming Complex Quantitative Systems Pharmacology Models with Model Reduction

Tom Snowden

Quantitative systems pharmacology (QSP) combines computational modeling and experimental data to examine the relationships between a drug, the biological system, and the disease process. This emerging discipline integrates quantitative drug data with knowledge of its mechanism of action. QSP models predict how drugs modify cellular networks in space and time and how they impact and […]

Quantitative Systems Toxicology—Taking the Cue from Aristotle

Maria Saluta

“The whole is greater than the sum of its parts” -Aristotle This quote from the great 4th century BCE Greek philosopher and scientist has become the mantra for many endeavors, sectors, organizations, and disciplines. From biology, chemistry, and physics to agriculture, engineering, and business, it is the foundation for synergy. What is the connection between […]

Using Model Reduction to Bridge the QSP-Pharmacometrics Divide

Tom Snowden

Quantitative systems pharmacology (QSP) models are generally too large to be validated or fit in a traditional sense and they can become intractable to standard methods of analysis or even to the modeler’s own intuition. Model reduction can alleviate these issues of complexity by eliminating portions of a system that have minimal effect upon the […]

Mechanistic Modeling of Genome Scale Molecular Interaction Networks

Andrzej Kierzek

Upon the completion of the Human Genome Project, the lead investigator, Dr. Francis Collins remarked: Science is a voyage of exploration into the unknown. We are here today to celebrate a milestone along a truly unprecedented voyage, this one into ourselves. Alexander Pope wrote, “Know then thyself. Presume not God to scan. The proper study […]
