Cristina has a deep background on the chemistry and application of cellulose and nanocelluloses: -Development of characterization methods based on image analysis obtained from electron, optical and/or confocal microscopy: aggregation state of nanocrystals, fibrillation degree of nanofibers, porosity of bacterial cellulose membranes, etc. -Studies of colloidal interactions. Currently working in polymers biotechnology, with polyhydroxyalkanoates (PHAs) and using bacterial cellulose as scaffolds.
