Position Description

“Weak ~kT scale interactions in suspensions of anisotropic particles”

Dr. Wirth is seeking applications from highly motivated individuals for one (1) doctoral position studying the weak ~kT scale interactions in suspensions of anisotropic particles. The central goal of this research is to develop and implement a novel instrument capable of the measurement and manipulation of colloidal interactions in suspensions of anisotropic particles. The technological need for this work resides in the integration of anisotropic nanomaterials, namely carbon nanotubes and graphene sheets, into chemical products with a microstructure that depends on particle/particle and particle/substrate interactions.

Dr. Wirth’s lab ( in the Chemical and Biomedical Engineering Department at Cleveland State University (CSU) studies the interactions, dynamics, and assembly of particles suspended in bulk fluids and at interfaces. In particular, the group seeks to measure and exploit weak ~kT scale interactions between complex colloidal particles, including carbon nanotubes, Janus particles, and ellipsoids, and subsequently leverage this new knowledge for implementation in a broad selection of industrial, engineering, and scientific areas. In addition to doing fundamental research, Dr. Wirth anticipates working with the coatings, biomedical, and oil & gas industries on the development of innovative new products and tools.

The Chemical and Biomedical Engineering Department is part of the Washkewicz College of Engineering at CSU. The Doctorate in Engineering (DRE) is a unique, college-wide interdisciplinary doctoral degree, with specialization in a specific discipline. The CSU campus is in the heart of downtown Cleveland and recently underwent a $500 million dollar renovation.

How to Apply

Individuals with a research interest in the broad fields of Colloid and Interface Science, Complex Fluids Engineering, Soft Matter, Electrokinetics, Nanotechnology, or another related field should considering applying. Applications will be evaluated on a rolling basis, but those who are interested should contact Dr. Chris Wirth ( by IMMEDIATELY with a letter expressing her/his interest and a CV that includes contact information for three (3) references. Potential students will need to meet the minimum requirements for the DRE program admission, as specified in the graduate catalog, and will need to apply for admission to the Doctor of Engineering in Chemical Engineering program.
