Pier Fiedorowicz
Graduate Student in Physics
 (Advisor: Eduardo Rozo)

My work focuses on developing an improved method for mass map reconstruction from weak lensing surveys. This work is primarily for the Dark Energy Survey and the Large Synoptic Survey Telescope but the code will be publicly available.

Elaheh Hayati
Graduate Student in Physics
 (Advisor: Tim Eifler)

I work on extracting cosmological information from weak lensing catalogs. These catalogs are either from publicly available observational data sets or from simulated LSST catalogs.

Matthew Kirby
Graduate Student in Physics  
(Advisor: Eduardo Rozo)

I work predominantly on galaxy clusters however my research interests range from observational cosmology to galaxy evolution. Currently, I am working on combining observations of galaxy clusters in optical, X-ray, and microwave to constrain the scatter in the statistical richness--mass relation and improve cosmological constraints from galaxy cluster number counts.

Paul Rogozenski
Graduate Student in Physics  
(Advisor: Elisabeth Krause)

I am interested in theoretical cosmology and interpreting cosmological observations from the Dark Energy Survey. Currently I work on metrics to quantify whether different cosmological probes are in tension, or consistent with each other.

Pranjal Singh
Graduate Student in Astronomy  (Advisor: Elisabeth Krause)

I'm interested in observational cosmology. Currently, I'm working on identifying Kinematic Lensing (KL) in galaxies using simulations and spectroscopic/imaging data from Keck, LBT and HST.

Erika Wagoner
Graduate Student in Physics  
(Advisor: Eduardo Rozo)

I’m broadly interested in observational cosmology, especially utilizing late time probes to study the expansion history of the universe. I’ve worked previously on methods of baryon acoustic oscillations with photo metric data, and my thesis work will involve a new method of measuring the Hubble constant using velocity dispersions of galaxies in clusters. I’m also working on alternative methods for mitigating observational systematics in large scale structure analyses, primarily for the Dark Energy Survey.

Jiachuan Xu
Graduate Student in Astronomy 
(Advisor: Tim Eifler)

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. I explore whether KL can be used with the instrumentation of the WFIRST mission.

Undergrad Students

Jay Gaurangkumar Motka
Major: Physics & Astronomy (Advisor: Tim Eifler )
I work on data compression schemes of tomographic power spectra with simulated data from the Dark Energy Survey.

Nick Sand
Major: Physics (Advisor: Eduardo Rozo )
I am developing code to do numerical calibrated jackknives with no randoms in numerical simulations to enable fast computation of clustering statistics, including error bars.

Adam Skora
Major: Physics (Advisor: Eduardo Rozo )
I use multi-wavelength data to characterize the selection function of photometrically selected and SZ-selected galaxy clusters.

Paxton Tamooka
Major: Physics (Advisor: Eduardo Rozo)
I am studying the velocity structure of satellite galaxies in massive galaxy clusters.
