Kenneth Showalter of West Virginia University is supported by a grant from The Theoretical and Computational Chemistry Program to continue his experimental research in the area of spatiotemporal dynamics in chemical systems. Showalter proposes three main lines of research: 1) studies of perturbation-induced spatiotemporal behavior; 2) the development of chemomechanical gel systems that respond to chemical waves and patterns; and 3) studies of spatiotemporal behavior in gas phase reactions. Experimental investigations will be combined with theoretical and computational analyses in each case.The study of nonlinear dynamics is an important tool for understanding complexity in nature. The dynamics of most biological systems involves spatiotemporal behavior, which remains a challenging and important topic in nonlinear dynamics. Chemical systems play an important role in advancing our understanding of nonlinear dynamics because they are particularly amenable to experimental and theoretical analyses and hence serve as ideal model systems. Showalter's research serves to elucidate the fundamental characteristics of chemical systems that exhibit pattern formation and complex space-time behavior.

西弗吉尼亚大学的肯尼斯·夏尔特（Kenneth Showalter）得到了理论和计算化学计划的赠款，以继续他在化学系统中时空动力学领域的实验研究。 Showalter提出了三个主要研究线：1）扰动引起的时空行为的研究； 2）对化学波和模式响应的化学机械凝胶系统的发展； 3）气相反应中时空行为的研究。 在每种情况下，实验研究将与理论和计算分析相结合。非线性动力学的研究是理解自然复杂性的重要工具。 大多数生物系统的动力学涉及时空行为，这仍然是非线性动力学中一个具有挑战性和重要的主题。 化学系统在促进我们对非线性动态的理解方面起着重要作用，因为它们特别适合实验和理论分析，因此是理想的模型系统。 Showalter的研究旨在阐明表现出模式形成和复杂时空行为的化学系统的基本特征。
