My main research interests lie in the field of quantum optics, with particular emphasis on its applications to quantum information science and quantum metrology. Quantum optics studies the quantum properties of light and ways in which these properties can be used to provide secure communications, perform complex calculations, and increase the sensitivity of measurements, among other things.

In recent years my research has focused on the generation and control of quantum states of light known as twin beams through the use of four-wave mixing in atomic vapors. The use of an atomic system for the generation of these quantum states offers distinct advantages. First, it makes it possible to obtain a large nonlinear interaction, which leads to a large degree of entanglement without the need of a cavity. This makes the twin beams intrinsically multi-spatial mode, which means that they contain spatial quantum correlations in addition to temporal ones. Second, the use of an atomic system leads to narrowband entangled photons close to an atomic resonance. As a result, it is possible to obtain an efficient interaction between an atomic system and the entangled photons, which allows for better control of the twin beams. This has made it possible for us to implement a quantum buffer and a quantum cloner for these entangled states of light.
