Research interests + projects

Prof. Orlando Rojas works toward supporting global sustainable development through research on the fundamental and utilization aspects of renewable resources, including lignocellulose, proteins and other biopolymers. His research aims to discover competitive alternatives for fossil materials. Specific research interests include:

  • Nanopolysaccharides (based on cellulose, chitin, starches and others)
  • Bacterial nanocelluloses
  • Cellulose derivatives
  • Lignins, colloidal lignins, nanolignins and their uses
  • Renewable biopolymers (hemicelluloses, proteins, chitin and chitosan, alginates and others)
  • Multiphase systems (emulsions, foams, dispersed systems), gels, aerogels
  • Films, filaments and hybrid materials
  • Nanocomposites
  • Bioactive systems
  • Fiber processing
  • Pulp and paper
