What are you working on? February 2013

This is the bimonthly 'What are you working On?' thread. Previous threads are here. So here's the question:

What are you working on?

Here are some guidelines:

Focus on projects that you have recently made progress on, not projects that you're thinking about doing but haven't started.
Why this project and not others? Mention reasons why you're doing the project and/or why others should contribute to your project (if applicable).
Talk about your goals for the project.
Any kind of project is fair game: personal improvement, research project, art project, whatever.
Link to your work if it's linkable.

The paper has been finished, and has been submitted to a journal. Now I'm working on four new projects, more or less concurrently:

An extension of the previous result a more complicated (and hopefully more realistic) model.
A technical result in a related area, for a different kind of tomography.
A completely unrelated theory involving scattering on orbifolds.
Some numerical results for the previous article and (eventually) number one.

The boyfriend and I are still together, and I'm planning on moving in with him in July, if all goes well.
