Research Interests

Theoretical problems in statistical mechanics, especially in the area of fluids.  Use of analytic theory, numerical analysis, and computer simulation to study structural and thermodynamic properties of liquid crystals, polymers, biological macromolecules, and other complex fluid systems.

Much of my recent research has been concerned with polymer chain conformation and collapse.  I am especially interested in the coupling between chain conformation and local solvent structure and have been developing an approach to map the "many-body" chain-in-solvent problem to the simpler "few-body" single chain problem.  This mapping is illustrated in the following Monte Carlo snapshot that shows a 50-bead hard-sphere chain (blue) in a hard-sphere solvent (red) at volume fraction 0.40 which we are able to represent as a single chain (green) interacting via a set of effective potentials.  See the publications below with my students Sayuri Ichida and Greg Petersen for more details.  This research is currently funded by a grant from the National Science Foundation Division of Materials Research (NSF-DMR grant 0804370).  In the past two summers six Hiram students have participated in and contributed to this ongoing research project.  [See my NSF Project Highlights].

I have also recently been investigating, in collaboration with Wolfgang Paul and Kurt Binder, phase transitions of an isolated polymer chain.  Using advanced computer simulation techniques we have been able to map out the complete phase behavior of a flexible square-well (SW) homopolymer chain.  Of particular interest is the finding that a chain with sufficiently short-range site-site interactions undergoes a direct freezing transition analogous the all-or-none type of folding transition exhibited by many small proteins.  Below is the temperature-interaction range phase diagram for a 128 bead SW chain.

Other Interests: Rock Climbing and Mountaineering

I've climbed seven grade VI's on El Capitan and solo aided several grade V's in Yosemite and Zion.  Now I live in Ohio ... enough said?  I'm still dreaming about at least one more route up the captain.  I do manage a trip to the Canadian Rockies most every year.  Most recent technical climb in Canada: solo ascent of the NW Ridge of Mt. Sir Donald (8/10) ... wild exposure with rime ice through the upper sections to keep me focused!  I was back in Canada this past summer.  Lots of rain but I did manage an ascent of Mt. Daly and went in to look at the routes on Mt. Fryatt.
