The study of accretion disk's morphology: Four papers were published on this topic. The first one details the variability of the inner edge of the accretion disk around HD 163296. We use parametric component modeling and chromatic image reconstruction. In the second paper we demonstrate the possibility of recovering images and velocity maps along the BrG spectral line in the object HD 58647. In the third paper, SAM-type data were used to search for sub-stellar companions in the inner cavities of accretion disks in a small sample of objects. In the fourth paper, we studied asymmetries in the accretion disk of LkCa 15 using SAM-type data.

The study of the structure of oxygen-rich AGB stars: One paper was published and another is under review on this topic. The existence of clumpy and irregular CO layers in which dust grains of magnesium-based compounds can potentially coagulate was demonstrated. In the second article, the photosphere of the star R Car was resolved, in which bright spots associated with convective cells can be distinguished. The reconstructed dynamical images have helped us to distinguish changes in these convective patterns. This is the first work reporting these changes in AGB-type stars. In addition, we collaborated in the study of the dust distribution of the star Betelgeuse with the MATISSE instrument of the VLTI.

The characterization of the effect of multiplicity in massive stars: The first images of the dust generated by the stellar wind collision of the binaries WR 137 and WR 140 were produced. The images of WR 137 are the first Fizeau-type interferometric reconstructions obtained with a space telescope. CASSINI-SAMPip reduction software was essential in the publication of this work. Additionally, a paper was published on the chromatic changes of the cavity produced in the collision region of the winds of the Eta Car binary. For this purpose, data with the MATISSE instrument of the VLTI in the mid-infrared were used.

Papers on the observing modes of the JWST NIRISS instrument: Two papers were published on the "Sparse Aperture Masking" and "Kernel Phases" observing modes. Both in collaboration with the Space Telescope Science Institute science team responsible for both observing modes for the NIRISS near-infrared camera.

Research on the central structure of AGNs: A paper was published on the structure of the dust torus around the supermassive black hole in the active galaxy Circinus. Mid-infrared data obtained with MATISSE-VLTI and the VISIR-VLT camera were used. The VISIR data were reduced with CASSINI-SAMPip.
