I am an engineer experienced in optics and biophotonics for biomedical and industrial applications. I combine optical, programming, and analyzing skills to develop new diagnostics tools for the early detection of eye diseases.

At ICTER, I investigate the two-photon vision phenomenon and its potential applications, like two-photon microperimetry. I am also involved in developing a 2-photon-excited fluorescence scanning laser ophthalmoscope system.

Two-Photon Excited-Fluorescence Scanning Laser Ophthalmoscope (TPEF-SLO)

The ability to noninvasively access metabolic processes during the visual cycle is crucial for developing therapies against retinal degenerative diseases. We have developed a protocol for obtaining in vivo two-photon excited fluorescence images of the fundus in the human eye. The visual cycle is a series of chemical transformations during which various fluorescent intermediates are […]

Two-photon vision

Vision allows for receiving stimuli from the surrounding world through electromagnetic waves from 400 to 780 nm, called visible light. It begins when a photon of such light is absorbed by the visual pigment of the photoreceptor in the light-sensitive part of the eye – the retina. Absorption of a photon initiates a series of […]

Er-doped fiber laser

Femtosecond lasers are used in many techniques in biophotonics, including multiphoton microscopy, two-photon fluorescence ophthalmoscopy, and two-photon microperimetry. These methods require precisely selected parameters of ultrashort pulses to ensure noninvasive and efficient imaging of the sample under study or examination of the patient. Titanium-sapphire lasers or parametric oscillators are most commonly used for this purpose. […]
