I am a mile under a mountain. IAmA grad student researching dark matter. AMAA
I'm a PhD student researching dark matter at LNGS, an Italian underground laboratory. Our experiment wants to be deep underground to block cosmic rays, which would otherwise be a big source of background signals that could hide the rare (and unblockable) dark matter events.
AMA about my job, including working underground and studying dark matter. I'm not a theorist, though, so don't expect expert answers to questions like "why do you think dark matter exists."
I'll be answering questions from ~11:30 -12:30 GMT, and then later in my evening--I wanted to start this while I was at work for the cool headline, but I'll have more time once I'm done with work and out aboveground. Edit: looks like no one's rushing me to get back to work, so I have a little longer... but I might disappear at any minute, sad to say.

Edit: just got approval from the boss to mention the experiment I work on. I work on the Darkside experiment
Edit: alright, think I'm done for the night. Thanks for the questions, everyone! And thanks to the other scientists and science fans who helped out.
I made a small soapbox post to take advantage of my little bit of internet celebrity: http://www.reddit.com/r/IAmA/comments/1cgeh1/i_am_a_mile_under_a_mountain_iama_grad_student/c9gkszq
