Dr Juan Sebastian Totero Gongora

Pronouns: He/him
  • Senior Lecturer / EPSRC Quantum Technology Fellow

Juan completed his PhD in Electrical Engineering in 2017 from KAUST University, KSA, following an MSc in Theoretical Physics of Disordered Systems (2012) from Sapienza University, Italy. In 2017 he joined the Emergent Photonics (EPic) Lab at the University of Sussex as a Research Fellow in Experimental Photonics to develop complex nonlinear imaging experiments using terahertz waves and unconventional THz nonlinear sources.

In 2019 Juan secured a “Helena Normanton Fellowship” from the University of Sussex and in 2020 a Leverhulme Trust “Early Career Fellowship”. Both projects focused on the role played by complex nonlinear interactions in the formation of a special class of nonlinear waves, known as laser cavity solitons, in micro-comb systems.

In July 2022, Juan joined Loughborough University as a Senior Lecturer and a member of the Emergent Photonics Research Centre. His current research, funded by a five-year EPSRC Quantum Technologies Career Development Fellowship, focuses on the integration of data-driven control techniques for high-power micro-comb lasers, and their application for complexity-driven neuromorphic photonics systems.

Research areas:

  • Data-driven control of experimental nonlinear photonic systems
  • High-power micro-comb lasers for quantum technology applications
  • Complex nonlinear wave interactions in multimode photonic systems
  • Complexity-driven neuromorphic photonics
  • Photonic Reservoir Computing
  • Quantum Reservoir Computing
