-For cosmologists, I am a modeler. I model different observables, including galaxy number counts, galaxy intrinsic shapes, cluster Sunyaev-Zeldovich (SZ) effect in the Cosmic Microwave Background (CMB), and growth of LSS, in order to confront theoretical assumptions and predictions with current and future observations.

+Stage-IV cosmic microwave background (CMB) experiments and galaxy surveys will open a wide and deep window into our universe and the cosmic large-scale structure (LSS), at both late and early times; CMBxLSS analyses provide a tomographic scan uncovering the evolution of the mysterious dark energy and the elusive dark matter. Unfortunately, hints of new cosmological physics beyond the standard model of cosmology are often convoluted by systematics from astrophysical processes. To effectively break this degeneracy requires explicit modeling of both signal and systematics—beyond the regimes of linear theory and standard summary statistics—and/or clever, consistent modeling of the signal when combining CMB and LSS. However, so far the two approaches have been largely explored as two separate dimensions. My past research explored and developed both approaches to elevate cosmological constraints, in particular, those on late-time new physics. My NHFP program is to merge these two directions into one single dimension where I will forward-model the growth of LSS, going from the early to late universe, in both CMB and LSS observables, at the map level. Late-time new physics is consistently encoded in the LSS growth history, hence naturally separated from the astrophysics which has a different time evolution.
