Research Interests 

My research focuses on the phenomenology of axions, a very light particle that is a very promising candidate to constitute the entirety, or a part, of the mysterious dark matter that makes up 25% of the universe's energy budget. 

In the past, I have studied how a collection of these particles, bound together by their own gravity or other types of interactions, known as "axion stars", can convert to photons when they interact with the magnetic field of a neutron star or the magnetic field of the galaxy. 

Currently, I am working on the gravitational waves these axions will emit when they form a so called "gravitational atom" around a spinning black hole. A perturbation by a companion star will cause them to emit monochromatic gravitational waves,  which can be detectable by future space-based gravitational wave detectors. 

Another research topic I am pursuing is the imprint that very light axions, with mass 29 orders of magnitude smaller than the mass of the electron, will leave on the large scale structure of the universe. Their density perturbations exhibit distinct features and, using power spectrum data, I am attempting to constrain their mass and their dark matter fraction.
