Biography

I am a Postdoctoral Researcher in the Department of Astronomy at the University of Arizona. My research interests include cluster cosmology, small scale cosmology and galaxy and halo assembly bias. I have extensive experience in applying halo occupation distribution methods to N-body simulations to model and emulate novel combinations of cosmological observables down to small scales. My current work is focused on modeling optical cluster projection effects to enable small scale cosmological analyses of cluster lensing and cross-correlations. I am also interested in studying galaxy assembly bias in the local Universe.
