I work on Kinematic Lensing (KL), a new idea to combine spectroscopic and imaging information that enables us to use the distortion of galaxy shapes by the gravitational potential of large-scale structure to constrain cosmology, and its implementation with cosmological galaxy surveys like Roman Space Telescope and Dark Energy Spectroscopic Instrument. I’m also devoted to improving the multi-probe analyses of cosmological surveys by jointly modeling galaxy clustering, galaxy weak lensing, and CMB lensing.
