David L. Bostick's Modeling/Simulation Gallery.

These images represent some of the simulation and modeling work I have done in the past. I have not necessarily written (i.e. published) papers about all of them. In addition, a good deal of my work is not acually represented here. This is just for a small taste of the kind of work that I do.

Note that these images are copyrighted by me, David Bostick (01/10/2007), and should not be used without my permission or without appropriate citation.

Halorhodopsin close-up

Close-up snapshot of halorhodopsin with chloride ion in a position corresponding to a quasi-L state.

40 mol % Cholesterol:DPPC system

Cholesterol is shown as space--filled atoms. DPPC is colored in green. The phosphorus and nitrogen atoms of the DPPC headgroup are shown as yellow and blue spheres respectively.
