Welcome Hao! I have added you to the waiting list for the next instructor training at UF which will likely be in the spring some time.
If you're interested in participating in the R meetup that happens at UF (Wednesday evenings in MSL [1]), Dan Maxwell who is also on this list runs it. Justin and Ben are the current students involved and they're also on the list as well and quite possibly
have already responded to you directly.
There is also a data science student group here at UF that might interest you. They are most active on Facebook but you can find background on them at their web site [2].
