Introduction
My main area of research is biophotonics and I focus on the use of low-coherence interferometry, fiber-optic technology and the application of optical measurements in biomedicine. Apart from my main research subjects, I also deal with constructing an electronic system supporting behavioral therapy for children with autism.
