Seminar

Screening for Noise in Gene Expression Identifies Drug Synergies

Tuesday, September 16, 2014, 12:30 PM - 1:30 PM
Leor Weinberger, Associate Professor, The University of California - San Francisco

Abstract: Over the past decade, a stubborn debate has persisted in biology regarding the role and importance of stochastic gene-expression processes (i.e. "noise"). This roughly parallels the Bohr-Einstein debates that occurred in Physics in the ear more  »

Seminar

Long Time Dynamics of Biological Molecules

Wednesday, September 10, 2014, 4:00 PM - 5:00 PM
Ron Elber, Professor W.A. ‘Tex’ Moncrief Chair in Computational Life Sciences, University of Texas at Austin

We will show how (many) short trajectory fragments of picosecond lengths can be used to exactly study long time dynamics of biomolecular systems. The short trajectories are used in an exact probabilistic equation that accounts for transitions between more  »

Seminar

Molecular and Coarse-grained Views of Protein Dynamics in the Unfolded State

Tuesday, September 9, 2014, 12:00 PM - 1:30 PM
Dmitrii E Makarov, Professor, The University of Texas at Austin

Abstract: The nature of the unfolded state of proteins is essential for our understanding of how proteins fold or how intrinsically disordered proteins accomplish their biological function. Computational studies of the unfolded ensemble, however, fac more  »
