About

  • Presently I am working at the Italian Institute of Technology, where I am involved in several projects whose aim is the development of new technologies for the design and amelioration of retinal prostheses. Within the European Flagship of Graphene, I am studying the possibility to insert Graphene as a component of photoactive implantable devices, in order to increase light-transduction efficiency.
  • At the Institute of Neurosciences in Montpellier (INM) I characterized the electrophysiological function of Retinal-Pigment-Epithelium cells reprogrammed from human-patient-derived iPS cells. I recorded with the Patch-Clamp technique the activity of subfamilies of expressed ion channels such as L-Type Calcium channels, Calcium-activated BK Potassium channels, and Voltage-dependent CLC-2 Chloride channels.
  • At the Institute of Functional Genomics (IGF) in Montpellier I characterized the physiological properties of cardiac pacemaker-like cells differentiated from skeletal muscle-derived stem cells (skMDPM cells). With this aim, I mainly used Patch-Clamp whole-cell recordings, live Confocal-microscope line-scan measurements, and Edge-detection.
  • During my PhD period, I acquired knowledge on electrophysiological and biomolecular techniques that I used for biophysical characterization of gating mechanisms in viral ion channels such as PBCV-1 Kcv, Influenza-A PB1-F2 and Influenza-A M2. With this purpose, I performed Single-ion channel recordings and Macro-current measurements on Xenopous laevis oocytes and artificial membrane bilayers.
