# Research interests

My research interests currently focus on quantum measurement theory and
geometric properties of quantum state space. I also study
open-quantum-system dynamics (particularly stochastic evolution) and have
evaluated tomographic schemes employing weak measurements.

## Talks

Here is a list of talks I have given or am scheduled to give. I provide them in
two formats: [browsercast][browsercast] (which plays the audio back in sync
with the slideshow in your browser) or slides only (which allows you to view
the HTML slides at your own pace in your browser).

If you are watching a browsercast and the play/pause button is not responding to
clicks, the spacebar works to pause or resume playback (I may have messed
something up when playing with the CSS...)

Some of my slides also use MathML for equations, which looks great in Firefox
but doesn't have good support in Chrome (although I just started playing around
with the [Math anywhere][mathanywhere] Chrome extension, which does a decent
job).
