Jason DeRouchey is an Associate Professor in the Department of Chemistry at the University of Kentucky.  He received his B.S. degree in Chemistry from the University of Texas at Dallas in 1996.  Professor DeRouchey then obtained a MS and PhD in Polymer Science and Engineering at the University of Massachusetts-AmHerst.  He first began working with questions of dynamics and DNA as a Alexander von Humboldt Fellow working with Joachim Rädler at the Institute of Experimental Physics at the Ludwig Maximilians Universität (LMU) Munich.  Dr. DeRouchey then joined the Laboratory of Physical and Structural Biology at the National Institute of Child Health & Human Development (NICHD) at the National Institutes of Health (NIH) as a IRTA fellow working with V. Adrian Parsegian.



The DeRouchey laboratory is broadly interested in understanding the forces, structures, and dynamics that govern the interaction of biologically significant macromolecular assemblies to address problems in biology and biomedicine.  Using interdisciplinary methodologies in chemistry, physics, and medicine, we focus currently on issues related to DNA condensation in vitro and in vivo and the delivery of artificial gene constructs.  Learning the strength, specificity, and reversibility in associates of biologically important macromolecules, typically in crowded environments, is crucial to our understanding of gene and cellular function and for effective and rational drug design.
