Chemical Engineering Research Interests
|
Biomolecular and Cellular Engineering
| |
The design and analysis of engineered systems based on or inspired by biology. This research includes the development of tailored molecular therapeutics, tools for manipulating and designing functional biomolecules, biomimetic materials, and biomolecular sensing.

Chemical Reaction Dynamics and Catalysis
| |
Physical phenomena arising from the interactions between chemically reactive species, such as spatially symmetric states and chemical oscillations, are studied. The results have applications for diverse processes such as petroleum refining, combustion, and the transmission of neural signals. Work is also being done on deactivation and diffusion in catalysts.

Polymers
| |
Research encompasses the following areas: molecular characterization of synthetic polymers, polymer alloys, and filled systems; rheological properties of polymers; viscoelasticity of rubber; toughness and fracture of polymers; adhesion and adhesive joint strength; thermodynamics of ionic polymers; and the effect of ionizing radiation on polymers and polymer degradation.

Rheology
| |
Flow behavior and physical properties of non-Newtonian fluids, including polymer fluids and particulate suspensions are studied; mechanical behavior of general particulate and fiber-reinforced media are also under investigation.
|
| |
|
Statistical and Molecular Thermodynamics
| |
Current research involves the following: predictions of thermodynamic behavior based on molecular theory and computer simulation and phase equilibria of highly non-ideal mixtures, with particular emphasis on supercritical extraction processes.

|
Molecular Transport Processes
| |
Molecular transport of matter, energy, and momentum through various complex media; facilitated and reaction-coupled mass and heat transport in systems ranging from biological media to petroleum reservoirs; prediction of transport properties, critical behavior, and transport in systems ranging from biological media to petroleum universal scaling rules for disordered media by means of the effective-medium approximation, percolation and renormalization-group theory, and computer simulations. Mechanical properties of disordered composites and brittle fracture, ductile behavior, and failure of materials.
