Research

My research focuses on the rheological characterization of molecular glasses. In particular, broadening of the glass transition in complex glass-forming liquids is studied. New constitutive equations are developed based on experimental data collected by advanced rheological measurement techniques. Glass-forming liquids investigated in this research include neat and polymer-modified bitumens (asphalts), petroleum oils and blends of simple glass-forming liquids. Correlations between the thermodynamic and dynamic signatures of the glass transition are also investigated. This collaborative research is supervised by Profs. H. Henning Winter (UMass Amherst) and Jukka Seppälä (Aalto University, Finland) and supported by Nynas Company, the Vilho, Yrjö, and Kalle Väisälä Foundation, and the Osk. Huttunen Foundation.

In addition, my research interests include characterization of viscoelastic materials by creep-recovery experiments, development of rheological test methods for the characterization of bituminous (asphalt) binders, and fundamental methods of viscoelastic data analysis.
