"Bayesian Success Stories in Astronomy"

This talk has two (somewhat orthogonal) purposes. In the first half, I will give an overview of current initiatives on statistics and data sciences at the University of Texas. These include our undergraduate and graduate-level courses, the new Ph.D program, the SSC consulting service, and the UT Summer Statistics Institute. I will also introduce the rest of our faculty (in absentia) and describe some of their areas of expertise and ongoing collaborative interests. I will also briefly describe a few ways in which big-data computing is changing the face of statistics research, and about our group's efforts in this area.

Second, I will highlight a few examples of Bayesian inference in astronomy:
- the inversion of color-magnitude diagrams to estimate star-cluster parameters
- Bayesian model selection and experimental design in exoplanet studies
- adjusting for multiplicities in large-scale screening

These examples are chosen arbitrarily both from my own work (alas, not very recent), and from the work of others (much more recent) with which I am familiar. They are intended to convey a sense of the different ways in which Bayesian methods can be useful.
