Research Interests

           

         

From  www.w3.org/Talks/2001/1102-semweb-fin/ slide3-0.html

 

 

   I am interested in bringing undergraduates, and graduate students alike, on a safari. A fitting image for my research activities is that of the wisemen, each with a different perspective, trying to identify the proverbial elephant. Most projects consist of applying several techniques to study a system, using mathematical models to interpret the particular beast. Depending on interest, the focus of a student’s research may be more on the wisemen or more on the elephant.

 

 

Wisemen: The Techniques

 

Fluorescent Probe Techniques

Polarized Light Spectroscopy

NMR Spectroscopy & Relaxation Techniques

Thermal & Mechanical Analysis

Rheological Methods

 

Elephants: The Systems

 

Multiphase Polymer Blends

Micellar Solutions & Microemulsions

Polymer Latexes and Emulsions

Structured Soft Materials
