Research Interest
Biomedical optics uses advanced optical methods to investigate the interaction between light (usually visible and near infrared) and tissue with a focus on imaging (diagnostics, monitoring) and treatment (photodynamic therapy). Optical tomography is part of biomedical optics, and it creates volumetric images of an object by reconstructing images from light transmitted and scattered measurements. There are two approaches widely investigated: optical coherence tomography and diffuse optical tomography. Optical Coherence Tomography (OCT) uses ballistics photons and provides high resolution cross-sectional images of the internal microstructure of biological/medical systems. Limited penetration depth of the OCT system in the range of a few millimeters is compensated by a few micrometers image resolution, which is one order of magnitude higher than ultrasound imaging resolution. Spectroscopic OCT is an extension of conventional OCT which combines morphological and spectroscopic imaging. My research focuses on developing advanced spectroscopic OCT methods for clinical applications.
