Observations of supermassive black holes (SMBH) in the local universe show a strong correlation between their mass and host galaxy properties. This may be a result of fueling and feedback between the SMBH and the host galaxy during its active phase as active galactic nuclei (AGN) which can be reflected in the host galaxy morphology. Local luminous AGN tend to reside in massive bulge-dominant galaxies while less luminous AGN (eg. Seyferts) reside in disk-dominated galaxies. However, the evolution of the AGN host galaxy through cosmic time is still unclear, especially at high redshift during the bulk of SMBH and stellar mass formation. Thanks to the high-angular resolution in the near-infrared of JWST NIRCAM, it is now possible to resolve the host galaxy of redshift 2-4 AGN with 2-10 keV luminosity of logLx=43-45. Here, we present our preliminary results on the morphology of 1250 X-ray-selected AGN detected from the C-COSMOS survey within the footprint of the COSMOS-Webb program. Using the NIRCAM images, we first fit sersics profiles to the AGN type-2 host galaxy and perform AGN host galaxy decomposition for type-1 AGN.
