Dr. Ioanna Theodorou specializes in molecular imaging and nanomedicine. Her PhD  was focused on the implementation of a prototype optical (and molecular) imaging tomography device, to investigate the in vitro and in vivo bio-distribution of fluorescent nanoparticles and nucleic acid aptamers, -as well as their tumour targeting and elimination-, using animal models of cancer. Her work highlighted the importance of non-invasive longitudinal studies to visualize intact organisms and monitor biological processes, and opened new perspectives to the development of multimodal nano-objects, for applications in pathology diagnosis and drug delivery to sites of disease. During her post-doctoral fellowship, she studied the biophysical characterization of photo-convertible nanoparticles who´s novel properties allowed for versatile labelling of subcellular structures, whole cells and tissues with high spatiotemporal precision, paving the way for applications in bio-imaging such as confocal microscopy, cell migration studies, and cell sorting. She also lead the R&D of novel optical probes, for enhancing the sensitivity and performance of in vivo and in vitro imaging technologies, particularly the development of new bioluminescent probes using molecular biology tools, at the Photonic BioImaging Unit of Technology and Service at the Institut Pasteur in France. In April of 2022, she joined the Institute of Materials Science of Madrid (ICMM/CSIC), to work on a FLAG-ERA Consortium funded project (MARGO), centered on the implementation of graphene oxide-based biomaterial scaffolds, modified by laser-driven processes that enhance their applicability in tissue engineering, and particularly bone regeneration. She is currently integrated to the Service unit of Analysis by Non-Destructive Techniques of the National Museum of Natural Sciences of Madrid, rendering research service, using multidisciplinary analytical techniques (such as optical and electron microscopy, Raman spectroscopy, X-Ray micro-computed Tomography and X-Ray micro-diffraction) to determine the chemical, physical, molecular and morphological properties of biological specimens and materials.
