I gave Chris Wu his starter project on the astrometry user interface to introduce him to the group and our astronomical way of life (and to move the astrometry project forward, of course).
I worked out a very simple approach to the K+A galaxy modeling project (in which we use the statistics of K+A (post-starburst) galaxies to infer an event rate and starburst size distribution). The simplifying idea is to model not the space density of events, but to model the probability per unit time that any individual galaxy undergoes an event of a particular (fractional) size. With some simplifying assumptions, the project becomes very straightforward to implement and interpret. And Quintero has already done a lot of the heavy lifting on this one.
