My research focuses on understanding the evolution and components of the dark Universe by improving the cosmology survey analyses. I develop analytical and computational methods and tools enabling efficient calculations of small-scale nonlinear effects, important for inferring cosmology from current and future experiments (DES, LSST, WFIRST). Besides survey cosmology, I have a broad interest in other areas of astrophysics, including stellar dynamics and compact objects.

I am broadly interested in astrophysical systematics for weak lensing observables. I studied intrinsic alignment in redMaPPer galaxy clusters (Huang et al. 2016, 2018), and investigated mitigation techniques for uncertainties of baryonic physics from hydrodynamical simulations (Huang et al. 2019). Currently, I am working on constraining baryonic physics from Dark Energy Survey data.

My research is focused on probing inflation, the epoch of reionization and dark energy with the Cosmic Microwave Background. I am also keen on understanding how extensions of the LCDM model can be constrained via the combination of the CMB with low redshift probes. As a postdoc at the University of Pennsylvania, I researched how to test fundamental assumptions about the standard model using model-independent techniques. At the University of Arizona, I am deeply involved in interpreting data from the Dark Energy Survey (DES), in particular, I work on cluster cosmology and weak lensing.
