Research Interests

In several of my previous projects, I researched how to correct for aberrations in an optical system in order to acquire images of diffraction-limited resolution. Currently, I am working on optical coherence tomography.
My primary goal is to develop optical methods that enable us to access structural and functional details of biological tissues. In particular, I am aiming to create technologies that are useful in a practical sense for laboratory or clinical settings, not just as a proof-of-concept.
