Improving and applying atomistic simulation to study biophysical conformational dynamics
Abstract/Contents
- Abstract
- Models are tools used to interpret and draw conclusions from nature. Molecular dynamics (MD) simulation is a powerful technique for modeling complex atomistic systems such as biomolecules. In this dissertation, I discuss how one can improve and apply MD simulation in order to learn about biophysical phenomena. I first discuss how to improve the representation of the underlying physical interactions in a simulation. Chapter 2 discusses the optimization method, and 3 discusses how to rigorously characterize a resultant potential function. I then discuss how to use Markov state modeling to derive an interpretable mechanistic characterization of a simulation dataset. Chapters 4 and 5 apply this framework to study the conformational dynamics of the TREK-2 and CLC-2 ion channels, respectively. A brief introduction to the topics of MD simulation, force field optimization, and Markov state modeling is given in chapter 1. There remains a lot of work to be done before simulations are able to mimic reality with high fidelity. However, I am optimistic that with increasing data availability and improvements in optimization methodology, simulation will prove itself progressively more useful for studying dynamics at atomic resolution.
