I am a postdoctoral research assistant in point spread function (PSF) modeling for the Euclid mission. I test/verify the PSF modeling algorithm and investigate the impact of PSF model bias on the weak lensing (WL) shear measurement. During my Ph.D. supervised by Prof. M. James Jee at Yonsei University in South Korea, I used my WL analysis and estimated the mass of galaxy clusters at high redshift (z > 0.8) observed by the Hubble Space Telescope. My WL results of high redshift clusters confirm that extremely massive high-z clusters are compatible with the LCDM cosmology. I am also interested in building mass scaling relations for high redshift clusters, which will serve as leverage to determine accurate masses.
