The Dickson Lab’s core research efforts are directed at developing new methods for the simulation of rare events in molecular systems, and developing network models for the analysis of these simulations. Currently this research is focused on modeling long timescale protein-ligand binding pathways, and identifying the molecular interactions that govern ligand binding kinetics. Another driving question is how ligand binding impacts protein structure and dynamics. The Dickson Lab is developing computational tools to examine this impact, including how ligands modulate protein stability upon binding. Additionally, in a collaboration funded by the Human Frontiers Science Program, the Dickson Lab is developing mathematical models to report on chaperone activity inside living cells using the readout of a fluorescent biosensor that monitors protein foldedness.
Alex Dickson received his Ph.D. from the University of Chicago under Professor Aaron Dinner. There he developed new computational approaches to enhance the sampling of simulations that are driven out of equilibrium. Applications spanned from biomolecular systems, such as an RNA unfolding in a flowing solvent, to model systems from physics, such as sheared Ising models.
In 2011, he began as a postdoctoral researcher with Professor Charles L. Brooks III at the University of Michigan in Ann Arbor, where he continued developing new enhanced sampling methods for application to atomistic biomolecular systems. A novel method, "WExplore," allows for enhancement of sampling in an undirected fashion, and has been used to observe a wide variety of rare biomolecular phenomena. He also developed a set of analysis techniques that can help visualize the entire space of possible biomolecular conformations in a network plot.
As of August 2015 Alex has joined the Department of Computational Sciences, Mathematics and Engineering as a Assistant Professor.
