2014 Macbook Air keeps restarting unexpectedly with panic report

I have a 2014 Macbook Air running Yosemite 10.10.2 and I have been having a problem with my mac unexpectedly restarting ever since I updated to Yosemite. I can be doing anything from surfing the web to using word and then the screen will suddenly go black and show a screen that says "Your computer has restarted because of a problem." and then I'm brought to my log in screen. Afterwards I get a dialog box that has the same message and then asks if I would like to send a report. I send a report every time but nothing new's changed and this problem is getting annoying and I'd like to know how to fix it. I've tried researching it but haven't quite found anything relevant. I've included the error report below in hopes that someone can let me know what exactly is causing this error and hopefully how to fix the issue. Thanks!
