I am a Graduate Fellow in the Department of Astronomy at The Ohio State University working with Professor David Weinberg on a variety of topics related to cosmology and the galaxy-halo connection. Currently my primary research interest is in using galaxy clusters as cosmological probes. My collaborators and I have shown that a combination of cluster weak lensing, cluster-galaxy cross-correlations, and galaxy auto-correlations can produce tight constraints on cosmological parameters (particularly the amplitude of matter fluctuations $\sigma_8$). We have also developed the capacity to very accurately emulate the signal of these observables and compute their observable covariances with the aim of applying these methods to data.
I am also interested in halo and galaxy assembly bias. I have worked on researching the origin of halo assembly bias, and found that a variety of halo properties are tightly correlated with proximity to a massive neighbour halo. This ‘‘neighbour bias’’ accounts for the nearly all of the halo assembly bias signal in many cases. I am also currently working on constraining the level of galaxy assembly bias in SDSS using novel combinations of galaxy observables and the ELUCID constrained simulation.
