Let us introduce you to the team!

Antonio Ambrosio

Principal Investigator

Antonio Ambrosio holds a MSc. degree in Condensed Mater Physics from the University of Naples Federico II and a Ph.D. degree in Applied Physics from the University of Pisa. After six years as a Senior Scientist at Harvard University, in September 2019 Antonio became the PI of the Vectorial Nano-imaging @ IIT, dedicated to the development of metasurface-based optical nanodevices and new optical near-field imaging and spectroscopy techniques for 2D materials, polymers and nanostructured surfaces.

Stefano Chiodini

Post Doc

Stefano Chiodini obtained his BSc. and MSc. Degrees in Physics from the University of Bologna in 2010 and a PhD in Physics in 2012 from the same university. After several years as a postdoc in pioneering groups focused on Atomic Force Microscopy research, Stefano joined the Vectorial Nano-imaging group in 2020 as a postdoc, contributing to developing Scanning Probe Microscopy techniques to study the optical, electronic and mechanical properties of 2D materials, small-molecules and polymers.

Sara Moujdi

Post Doc

Sara Moujdi obtained her MSc. in Process and Materials Engineering from the University of Sidi Mohamed Ben Abdellah in Morocco. She obtained her PhD in optics and photonics at the University Mohammed V, in collaboration with the Moroccan Foundation for Advanced Science, Innovation and Research (MAScIR). Sara joined the Vectorial Nano-imaging group in 2022 as a postdoc contributing to the development of reconfigurable polymeric optical devices.

Andrea Mancini

Post Doc

Andrea Mancini obtained his Master's degrees in Physics from the University of Rome La Sapienza in 2017 working with Prof. Michele Ortolani. His thesis was focused on applying photothermal expansion AFM to study at the nanoscale the near-field interaction between plasmonic antennas and molecular vibrations. In September 2018 he joined the group of Prof. Stefan Maier at the Ludwig Maximilian University of Munich where he investigated Surface Phonon Polaritons through scattering SNOM. He obtained his PhD in February 2023. In March 2023 he joined the Vectorial Nano-imaging group of Dr. Antonio Ambrosio working on scanning probe microscopies.

Nicola Melchioni

Post Doc

Nicola Melchioni obtained his MSc in Physics at the University of Pisa in 2018. His thesis was carried out in Dr Frank Koppens' group at the Institute of Photonic Sciences (ICFO) and aimed to observe light-matter interaction at the nanoscale in Vander Waals heterostructures. He joined Professor Alessandro Tredicucci's group at the Scuola Normale Superiore in Pisa, where he studied the confinement effects of electrons and light in graphene devices with a lateral structure. Nicola joined the Vectorial Nano-imaging group led by Dr. Antonio Ambrosio in July 2023, working with optical and scanning probe microscopy to explore the properties of 2D materials.

Michael de Oliveira

PhD Student

Michael De Oliveira obtained his BSc in Astronomy & Astrophysics, BSc (Hons) and MSc in Physics with distinction from the University of the Witwatersrand, South Africa. During his time at the Structured Light Group of Prof. Andrew Forbes his research focused on exploiting structured light for quantum cryptographic applications. Michael is now pursuing his PhD in collaboration with CNST-IIT@PoliMi, supervised by Dr. Antonio Ambrosio. His current research focuses on using metasurfaces to structure complex light fields.

Giacomo Venturi

PhD Student

Giacomo Venturi received his M.Sc. degree in Physics at University of Pisa, with a thesis dissertation related to the phenomenon of coherent perfect absorption in chiral metamaterials. Since November 2020 he has been part of Antonio Ambrosio's group at CNST-IIT@PoliMi, investigating two-dimensional materials physics with optical and scanning probe microscopy methods.
