| Tom Woolf, Johns Hopkins University, School of Medicine |

Tom Woolf is currently an Associate Professor at Johns Hopkins University. His home department is Physiology, but he is also appointed in Biophysics and Biophysical Chemistry and in Biomedical Engineering. His group's research interests center on the biophysics of membrane systems and on the computational issues associated with relative free energy calculations. He studied physics at both Stanford (BS) and The University of Chicago (MS) before his Ph.D. at Yale (1990, Biophysics). His doctoral thesis work involved small networks of nerve cells and addressed issues of ion channel function. Postdoctoral work, with Benoit Roux in Montreal, was concerned with the model ion channel gramicidin.
Since arriving at Hopkins (1994), Tom's group has published simulations related to peptide:lipid interactions (glycophorin transmembrane domain, WALP, individual bacteriorhodopsin helices), ligand binding (fatty acid binding proteins), larger membrane proteins (rhodopsin and bacteriorhodopsin), salt effects on membrane bilayers and coarse-grained models of membrane fusion (with Mark Stevens). In addition, Tom's group has developed new methods for relative free energy calculations (Dynamic Importance Sampling) and has been exploring ways to improve the accuracy and efficiency of relative free energy calculations (extrapolation and funnel sampling methods, for example).

Emerging approaches to computation of peptide folding, electrified interfaces and drug binding for biomembrane systems
Thomas B. Woolf, Johns Hopkins University, Dept of Physiology, 725 N. Wolfe St., Baltimore, MD 21205, USA
This talk will emphasize emerging and developing work on three topics of interest to the conference. The first part of the talk will address issues related to the simulation environment. In particular, we are currently examining ways to create an explicit electrified interface for simulations of membrane systems. The second part of the talk will address on-going simulations of alpha-helical peptide folding within the context of membrane systems. In the third part of the talk, recent developments in free energy methods that can be applied to the computation of ligand binding for membrane proteins will be presented.
