My research focuses on the structural and dynamical properties of complex fluids, including single-chain polymer systems, Langmuir monolayers, and lipid bilayer membranes. These polymeric systems have practical applications in thin-film technology and have environmental applications, such as employing biofilms in soil remediation processes (which links well with UPEI's expertise in ecotoxicology). Additionally, this research has vital biomedical implications. For example, studies on the coil-globule and globule-solid transitions for isolated polymers in solution are essential to obtain insight into some of the key features that dominate the protein folding process. In my proposed research, I will use discontinuous molecular dynamics (DMD) simulations to examine the effects of varying different parameters, including the monomer/solvent size ratio, on both the collapse and freezing transitions for homopolymer and heteropolymer systems.

我的研究重点是复杂流体的结构和动力学性质，包括单链聚合物系统，朗缪尔单层和脂质双层膜。 这些聚合物系统在薄膜技术中具有实际应用，并具有环境应用，例如在土壤修复过程中使用生物膜（这与UPEI在生态毒理学方面的专业知识有很好的联系）。 此外，这项研究具有重要的生物医学意义。 例如，对溶液中孤立聚合物的螺旋-小球和小球-固体转变的研究对于深入了解蛋白质折叠过程中的一些关键特征至关重要。 在我提出的研究中，我将使用不连续分子动力学（DMD）模拟来研究不同参数的影响，包括单体/溶剂尺寸比，对均聚物和杂聚物系统的崩溃和冻结转变。
