Professor Gelbart is supported by a grant from the Theoretical and Computational Chemistry Program to perform theoretical studies directed at understanding the nature of amphiphiles. Amphiphiles are molecules which consist of a hydrophobic oil-soluble portion, and an ionic or polar water soluble portion. Amphiphiles aggregate to form micelles, and they are also involved in lipid bilayers which comprise biological membranes. Professor Gelbart's research will focus on several of the fundamental features of amphiphiles including the bending elasticity of surfactant films, phase transitions between defect states of amphiphilic lamellae, and successive orientational orderings in adsorbed monolayers. The self-assembly process which gives rise to the micellar unit will be studied in an effort to determine the way in which flow fields (viscous forces) affect the size of micelles. When appropriate, Monte Carlo and molecular dynamics simulations will be performed.

格尔巴特教授得到理论和计算化学项目的资助，进行旨在了解两亲物性质的理论研究。 两亲物是由疏水性油溶部分和离子或极性水溶性部分组成的分子。 两亲物聚集形成胶束，它们还参与构成生物膜的脂质双层。 格尔巴特教授的研究将集中于两亲物的几个基本特征，包括表面活性剂膜的弯曲弹性、两亲片层缺陷态之间的相变以及吸附单分子层中的连续取向排序。 将研究产生胶束单元的自组装过程，以确定流场（粘性力）影响胶束尺寸的方式。 在适当的情况下，将进行蒙特卡罗和分子动力学模拟。
