4 mmeineke 1087 This dissertation has presented the work and research I have
5     accomplished in the past five years. Chapt.~\ref{chapt:RSA}
6     illustrates one of the first problems I had applied myself to. Given a
7     relatively simple model, could we account for the differences seen in
8     experiment? By using the methods described in Monte Carlo modeling, I
9     was able to write several simulations that provided a clear
10     explanation for the majority of the experimental evidence.
11    
12     Later in Chapt.~\ref{chapt:oopse} I present the work I had to do in
13     order to solve more complex research problems. It became clear, after
14     the work on the RSA simulations, that even simple simulations can take
15     a great deal of programming. If I were to simulate the bilayer
16     simulations I wanted to investigate, a sophisticated molecular
17     modeling package was needed. After examining the options available at
18     the time, writing an advanced simulation suite was the best method
19     of accomplishing my goals.
20    
21     Working with my colleagues we have developed {\sc oopse} to the point
22     where it is capable of many unique simulation features. It properly
23     integrates rigid body dynamics. It has the capabilities to model
24     dipoles rather than point charges only. It can use the MPI interface
25     to calculate the long range forces across multiple processors. And
26     lastly, it is open source, so that other scientists may use the code,
27     and contribute back to the project to enhance the package.
28    
29     Lastly Chapt.~\ref{chapt:lipid} presents the research for which I
30     originally set about the development of {\sc oopse}. The lipid model
31     was under continual development while {\sc oopse} was being
32     designed. In fact many of the integration ensembles in {\sc oopse}
33     were specifically written to continue development of the lipid
34     model. The set of simulations presented in the chapter proved that the
35     model was capable of spontaneously forming bilayers. It also explored
36     the properties of the bilayers formed over a range of
37     temperatures. Further extensions to the model will likely include
38     exploration of dipole strength on the head as well as varying chain
39     configurations (one chain versus two chains, etc.). However, at this
40     point there are many questions that can now be explored with this model
41     such as the inclusion molecules to diffuse through the bilayer, or
42     perhaps exploration of special phases such as the ripple phase.
