Research

Dr. Roberta Congestri is research scientist in the Department of Biology at the University of Rome “Tor Vergata”.

Her research interests include taxonomy, ecophysiology and ultrastructure of microalgae and cyanobacteria in aquatic biofilms and marine phytoplankton, especially toxic and bloom forming species. Electron microscopy and image analysis techniques; structural, 3-dimensional, and spectral analysis of biofilms by confocal microscopy. Applications in the field of biofilm based remediation of waters and biofouling monitoring. Traceability of algal toxins along the food chain by means of microsensors. Diatom photonics and micro-mechanics, ultrastructural analysis of diatom frustules, pore patterns, silica nanostructures and linking mechanisms for nanotechnology and biodesign.
