Hey Ibsh,

Good to know that you are considering Public health. You need to be more specific about speciality that you wanna pursue within PH to get more specific response to your question. If you want to do MS only, then Biostat seems a hot cake in the job market. However if you don't want to deal with mathmatical modelling, then epidemiology would be better- remember MS/MPH in epi would not take you that high in career ladder in future so PhD is recommended.

If you have any specific question, drop at epid08@gmail.com

Good luck!
