Statistics/Bioinformatics PhD Profile Eval?

[plant]

Undergrad: large public state school

Major: Applied Mathematics/ Statistics

GPA: 3.3 -- had trouble my first few quarters and did pretty average on my lower division math coursework

Major GPA:  3.6 / 3.8

GRE Scores (revised version): 
Q: 160
V: 155
AW: 4.0

Research Experience: None

Programming: R, Python, Matlab, C++

Jobs: Tutored math/stats for approx. 4 years.

Extracurricular & Volunteer: Very good and bountiful. I had many significant leadership positions. Though, I'm not sure if graduate admissions would care.

Courses taken: 9 Stats upperdivs, 7 Math upperdivs (including 4 proof-based courses)

Other courses: Taking 2 more stats grad classes this quarter.

About me:  My goal is to get into a PhD program in Statistics or Biostatistics to do research in health/sustainability/other environmental topics. Though, I am not sure if my GPA/scores are good enough, so I am also considering Masters programs.

Applying to UCD, UCSB, & Carnegie Mellon. I am very open to going international and I'm considering University of Utrecht and ETH Zurich. Any other suggestions for (US/non-US) schools are welcome.

Thank you for reading. Please be honest and constructive.
