I'm currently a third year civil engineering undergraduate at UCLA with a GPA of 3.0-3.5. I also do undergraduate research for a statistics professor on campus & intern for the city under the bureau of engineering. And I plan on becoming a member of Chi Epsilon, the honor society fraternity for civil engineers. If I continue this path, what are my chances of getting into Graduate School under the department of civil envinronmental engineering or mathematics?

I'm thinking of applying to UCI, UCB, Cal Tech, Harvard,... any suggestions?
