Current Research

I am a theoretical physicist working at the interface of quantum optics and quantum technologies. My current interests include the development of quantum-enhanced sensors and sensing protocols, identifying novel opportunities for quantum simulation in current or near-term hardware, and understanding collective effects in quantum many-body systems, especially in open quantum systems. I place particular emphasis on the experimental relevance of my research projects.
