## Who I Am:

An astrophysics Ph.D. (University of Chicago) working as an
astrostatistician
at Carnegie Mellon University. I work with
and other members of the International Computational Astrostatics (InCA) collaboration.
## Projects:

I am working or have worked on these problems:
- Cosmic Microwave Background
- Checking the effect of CMB map-making parameters upon observed CMB asymmetries (paper)
- Nonparametric estimation of CMB foregrounds (with related work on CMB nongaussianities)

- Nonlinear Data Transformation
- Using diffusion maps to . . .
- . . . estimate spectroscopic redshifts of SDSS galaxies and to detect outliers (paper)
- . . . estimate photometric redshifts of SDSS and DEEP2 galaxies (paper)
- . . . estimate properties of SDSS galaxies (paper)

- Supernovae
- Dark energy inference (paper)
- Inferring the velocity field of the local universe (paper)
- Semi-supervised methodology for classification (paper)

- Galaxy Morphology
- Using random forest to detect galaxies with disturbed morphologies (paper)
- Describing the evolution of the distribution of galaxy shapes

- Weak Lensing
- Applying Approximate Bayesian Computation (ABC) to weak lensing analyses

- Large Synoptic Survey Telescope (LSST)
- Development of Level 3 analysis tools as part of the Informatics and Statistics Science Collaboration

## Software

The following bits and/or pieces of software are free for you to use!
- Galaxy Morphology
- MIDLIB: IDL functions for computing M, I, and D statistics (a complimentary R package is planned)
