I have a GPA of 3.2 in my upper division major classes, and a 3.4 GPA in the last 5 quarters of my undergraduate studies. (My earlier lower-division work doesn't look so good with a sub 3.0 GPA) Graduated from UC San Diego in Biochemistry/Cell Biology. I have 4 years of work experience in Quality Control and R&D in the biopharmaceutical industry. I have completed one year of graduate school at Cal State university in Biostatistics with a 3.5 GPA. I am looking to apply for fall 2011 admission. Are there rankings for top MPH epidemiology programs in the US? What are my chances for admission?
