• Quantum Optics
• Quantum Sensing
• Microscopic modelling of quantum hardware
• Quantum Simulation
• Open Quantum Systems

My primary research interests are in studying the physics of quantum hardware platforms and identifying opportunities for quantum technology applications such as quantum sensing and quantum simulation. I am also interested in exploring open quantum systems and dissipation engineering for controlling and manipulating quantum systems.
