Chemical and Biological Engineering
Savvas has over 25 years of experience in the rheology of complex fluids including polymer melts and their blends, suspensions, gels and pastes. His group is using rheology as a probe to gain a better understanding of structural changes taking place in complex systems under flow. Primary focus is on polymer melts of controlled molecular architecture, nanocrystalline cellulose suspensions, gels and pastes. Another major theme of his research activities is in the area of surface modification to control wetting properties, including superhydrophobic and superoleophobic surfaces with applications in the area of biomedical sector.
