The Sixth q-bio Summer School: Biomolecular Simulations

From Q-bio

Description of Theme As system biology thrives to excel in providing cellular level behavior of complex biological systems, it has become imperative to integrate the molecular level events for better understanding at the system level. The objective of this theme is to provide training on computational methodologies to extract molecular level events at different resolutions. In addition we intend to provide a brief review on recent theoretical and computational methods and state-of the-art computing architectures. Finally, we will use examples from our own research to show that the real strength of these computational methodologies can only be materialized when combined with experimental studies. This section of the summer school is organized by "Gnana" S Gnanakaran. Please address all questions about this section of the summer school to its organizer.
