Katia Gallo

Katia Gallo is a Professor at the Department of Applied Physics, KTH Royal Institute of Technology, where she leads the Nonlinear and Quantum Photonics Group. She is actively involved in national and European quantum initiatives, including directing the Quantum Communication program in the Swedish Quantum Flagship (WACQT) and the National Quantum Communication Infrastructure (NQCIS) under EuroQCI. Her academic affiliations are centered at KTH, with prior research experience at the Optoelectronics Research Centre in Southampton, UK.

Education:

• MSc in Electronic Engineering, University ‘La Sapienza’, Rome, Italy (1997)
• PhD in Electronic Engineering (joint with Stanford University, USA)
• PhD in Physics, University of Nice-Sophia Antipolis, France (2001)

Her research focuses on nonlinear and quantum photonics, with core interests in integrated optics, ferroelectric materials, quantum optics, and biophotonics. She investigates the fundamental physics and applications of nonlinear wave interactions in photonic circuits, particularly using lithium niobate platforms. Her work spans from theoretical modeling to experimental realization of devices for all-optical signal processing, quantum communication, and sensing. She has made significant contributions to the development of thin-film lithium niobate photonic devices, including grating filters, superconducting detectors, and wavelength-sensitive systems.

Her recent publications (2017–2024) reflect a strong trend toward integrated quantum photonics, nanophotonic devices on lithium niobate, and biophotonic applications. Key themes include electro-optic tuning, superconducting single-photon detection, nonlinear frequency conversion, and surface-enhanced Raman scattering for sensing. The interdisciplinary nature of her work bridges physics, engineering, and materials science.

Scientific Awards and Recognitions:

• Swedish Research Council Senior Fellowship
• EU Marie Curie Fellowships (TMR and Intra-European)
• Leverhulme Trust Early Career Fellowship
• London Technology Network Business Fellowship
• Centre and South Italy IEEE Student Award
• KTH Rektor Prize for Equality and Diversity
