I no longer work in the area of astrostatistics. Some of my past work includes:

Galaxy Morphology

• Using random forest to detect galaxies with disturbed morphologies
• Using local two-sample testing to detect differences in morphological statistic distributions for binary classes of galaxies (e.g., high-mass v. low-mass, simulated v. real)

Photometric Redshift Estimation

• Using spectral connectivity analysis to estimate photometric redshifts

• Providing methods for estimating redshifts in the presence of selection bias

• Cosmic Microwave Background

• Checking the effect of CMB map-making parameters upon observed CMB asymmetries

Nonlinear Data Transformation

• Using diffusion map to . . .

  • . . . estimate spectroscopic redshifts of SDSS galaxies and to detect outliers
  • . . . estimate photometric redshifts of SDSS and DEEP2 galaxies
  • . . . estimate properties of SDSS galaxies

Supernovae

• Dark energy inference
• Inferring the velocity field of the local universe
• Semi-supervised methodology for classification
