Research interests
My main interest is in gaining additional information (beyond high-resolution 3D images) from optical coherence tomography (OCT) and photoacoustic tomography (PAT), such as quantifying tissue stiffness via optical elastography, mapping the refractive index based on OCT and vessel imaging in patient skin via OCT angiography (OCTA) and PAT.
Techniques, methods & infrastructure
- Optical coherence tomography (OCT) for skin (1.2-1.5 mm imaging depth) and small sample imaging
- Optical coherence angiography (OCTA) for visualizing skin vasculature (1.2-1.5 mm imaging depth)
- Photoacoustic tomography (PAT) for skin (up to 7 mm imaging depth) and absorbing small samples
- Elastography for soft tissue samples
