<p>I've read posts saying that people who apply in some research fields get accepted more readily than others who apply in more common fields. If so, which of the following would be the best to apply under?</p>
<p>Biology/vaccines
Biology/public health policy
Biology/epidemiology
Chemistry/ethanol
Chemistry/(the more general) alternative fuels
Chemistry/(even more general) energy sciences
Mathematics/public education
Mathematics/ecomonics
Physics/fuel efficient design</p>
<p>I have no preference from the above, so which do you guys think would be best? There are some pretty obvious themes above, so add any more ideas that you think of. Thanks!</p>
