0  Manager of Nanoimagin project:

- responsible for 2 PhD students and 2 trainees;

- modified a setup for diffraction imaging and holography in optical region of wave-lengths in order to achieve higher resolution and adapt the setup for biological objects, which are considered to be diffuse and alter the diffraction pattern;

- simulated in FDTD a single nanostructured high harmonics generation media in order to confine the optical field at certain wavelengths and obtain high numerical aperture for diffraction imaging setup and get higher lateral and axial resolution.

- 2 patents in process:

· apparatus for 3D/4D diffraction imaging of diffuse biological objects in vivo;

· tapered nanofibers fabrication method and application to imaging systems of live objects;

0  Member of VOXEL project:

- developped an algorithm allowing for sorting sparse images obtained from X-radiffraction measurements and as a results receive a data with sufficient signal to noise ratio allowing for following reconstruction of a 3D object;

- co-author of 1 article in process: 3D stereo single acquisition imaging using highg harmonics generation.
