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.

Michael de Oliveira

Post Doc

Michael De Oliveira obtained his BSc in Astronomy & Astrophysics, BSc (Hons) and MSc in Physics with distinction at the University of the Witwatersrand, South Africa. His early research was conducted under the guidance of Prof. Andrew Forbes at the Structured Light Group, where he explored the potential of structured light in quantum applications. He recently earned his PhD from the Politecnico di Milano, in a joint effort with the Italian Institute of Technology (IIT), where he was supervised by Dr. Antonio Ambrosio. His thesis focused on structured light, exploring the intricate manipulation of its multiple degrees of freedom—including polarisation, phase, amplitude, frequency, and temporal control—to unlock new potentials in optics and photonics.

Giacomo Venturi

Post Doc

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.

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.

Lin Nan

Post Doc

Lin Nan earned their PhD from the Chair of Prof. Stefan Maier at Ludwig Maximilian University of Munich, focusing on probing light-matter interactions within resonant single nanoantennae and metasurfaces. In 2024, they joined Dr. Antonio Ambrosio's Vectorial Nano-imaging group as a postdoctoral researcher, delving into the optical characteristics of van der Waals materials.
