I haven't heard any info about funding yet from UCI and I'm not sure about the funding opportunities on campus. Congrats on your CMU admit. Was that for Pittsburgh or Silicon Valley? Either way, that's ballin!
It's early in the game, U are still in the running. I think they stop admitting in mid-May, if I'm not mistaken. I turned in my app on Jan 15th and heard back in a month. What a turnaround! My stats are fairly decent, but I had a conference pub and three solid recs. Hang in there!
