I am an Imperial College Research Fellow at the department of Materials. My research interests focus on the design, synthesis and characterization of inorganic nanoparticles and nanocomposites (silica, ceria, SPION and gold) for biomedical applications with particular interest in drug delivery and antioxidant system. The nanocomposite particles are used for the treatment of neuro-degenerative diseases, osteoporosis, cancer and tuberculous meningitis. 


In 2007 I graduated in Pharmaceutical Chemistry at the University of Sassari. I started my adventure in nanobiotechnology with an internship at University of L'Aquila (2008). From 2010  to 2012 I was post-graduate Research Assistant, in the Laboratory of Materials Science and Nanotechnologies led by Prof. P. Innocenzi working with nanomaterials with antioxidant property for biological applications. In 2016 I obtained a PhD in nanochemistry, nanomaterials and functional materials at University of Sassari under the supervision of Prof. L. Malfatti. In 2016 I was awarded a Marie SkÅ‚odowska Curie individual fellowship, with a project focused on Inorganic therapeutic nanoparticles for osteoporosis under the supervision of Prof. J.Jones  (2016-2018). From 2018 to 2019 I was postdoc at Imperial college working on fluorescent probes with exceptional brightness for early diagnosis of breast cancer under the supervision of  Dr. Fang Xie.

During this time, I was also part of exchange projects at the University Hospital of Zurich, working on neurodegeneration in Bovine Spongiform Encephalopathy, and at CSIRO in Melbourne developing skills working on composite materials based on Metal Organic Frameworks and cerium oxide.

I have been visiting researcher at University of Sassari.
