Summary of Expertise:

Listed with other top experts in: 

Expert has published numerous papers on surfactant and polymer adsorption at water-solid interfaces.
 • 

adsorption

A great deal of his work involves characterization and properties of amorphous polymers, especially polystyrene and its various derivatives.
 • 

amorphous polymer

He earned B.S. and PhD degrees in Chemical Engineering.
 • 

chemical engineering

He has expertise in colloidal polymers in solutions, e.g. latex particles as well as biodegradable nanoparticles for drug delivery.
 • 

colloid

He has published many papers on physical chemistry aspects of colloids and interfaces.
 • 

colloid and interface chemistry

He worked one summer in the Composites Lab at Tinker, and has published papers on studies of curing kinetics as well as interface modification of fibers used in thermosetting composites. He has also studied thermoplastic composites extensively, in particular those involving carbon nanotubes.
 • 

composite material

He has characterized composites using electron and atomic force microscopy, rheology, calorimetry, various mechanical tests as well as small and wide-angle x-ray scattering.
 • 

composite material characterization

He has published papers on a wide-variety of both thermoplastic and thermoset composites, and has written a book chapter on thermoplastic material selection.
 • 

composite material selection

He has used both static and dynamic contact angle to characterize the surface of solid materials.
 • 

contact angle measurement

He has studied heat conduction in differential scanning calorimetry extensively.
 • 

heat conduction

His expertise is solid-liquid interfacial tension measurements, and processes whether these types of surface interactions are important.
 • 

interfacial tension

His expertise is solid-liquid interfacial tension measurements and has used a wide variety of instruments to characterize the surface energy of solids.
 • 

interfacial tension measurement

Because of his expertise in thermoplastic polymer composites, he knows a great deal about compounding of solid fillers in particular.
 • 

polymer compounding

He has characterized composites using electron and atomic force microscopy, rheology, calorimetry, various mechanical tests as well as small and wide-angle x-ray scattering.
 • 

composite material testing

He has written a book chapter on thermoplastic material selection.
 • 

polymer selection

He has studied how heat transfer affects measured quantities for a polymer in a Differential Scanning Calorimeter and hence has a fundamental understanding of unsteady state heat transfer in polymers.
 • 

polymer heat transfer

He has a fundamental understanding of how the various treatment process (e.g. plasma, flame) affect surface properties of polymers, especially with respect to adhesion. Primarily this expertise comes from his work on printing on plastics.
 • 

polymer surface chemistry

He consulted for a company that tested a new type of devulcanized rubber, and hence knows a great deal about rubber compounding.
 • 

rubber compounding

He has taught classes on surface chemistry at the University, and has published many papers that deal with surface chemistry of polymers and mineral oxide surfaces.
 • 

surface chemistry

One of his major research areas has been adsorption of surfactants at the solid-liquid interface. Further, he is the new Associate Director for the Institute for Applied Surfactant Research.
 • 

surfactant chemistry

He has written a book chapter on thermoplastic material selection.
 • 

thermoplastic material selection

Because of his expertise in thermoplastic polymer composites, he knows a great deal about compounding of solid fillers in particular.
 • 

thermoplastics compounding
