About the Seminar:

"Using Computer Simulations to Advance our Understanding of Biological Systems at the Atomic Level"

Classical molecular dynamics simulations based on atomic models play an increasingly important role in a wide range of applications in physics, biology and chemistry. The approach consists of constructing detailed atomic models of the macromolecular system and, having described the microscopic forces with a potential function, using Newton's classical equation, F=MA, to literally "simulate" the dynamical motions of all the atoms as a function of time. The calculated trajectory, though an approximation to the real world, provides detailed information about the time course of the atomic motions, which is impossible to access experimentally. Specialized free energy simulations are also an important route to establish a strong connection to experiments. The development of efficient methods for simulating slow conformational transitions is another subject of great interest in computational studies of biomolecular system. A powerful paradigm for mapping the conformational landscape of biomolecular systems is to combine free energy methods, transition pathway techniques and stochastic Markov State Model based massively distributed simulations. These concepts will be illustrated with a few recent computational studies of Src tyrosine kinases, K+ channels, and the P-type ion pumps.


About the Speaker:

Benoit Roux was born in the city of Montreal, Canada, in 1958.  In 1981, he received a B.Sc. in Physics from the University of Montreal, followed by a M.Sc. in Biophysics in 1985 under the supervision of Remy Sauve.  In 1990, he obtained a Ph.D. in Biophysics from Harvard University under the direction of Martin Karplus. He previous held positions at the University of Montreal, and the Weill Medical College of Cornell University. He has been at the University of Chicago since 2005, where he is the Amgen Professor in the Department of Biochemistry and Molecular Biology and holds a joint appointment in the Chemistry Department as well as Argonne National Laboratory.
