Your best bet is going to be getting as much experience as possible. In the end sure El Bulli does hire a couple food scientists, but getting that job is like winning the lottery. Majority of people that work there worked their butts off for the last 5-10 years and met the right people. For the restaurants you are looking at, elbulli and alinea, they are going to take either a person with tons of experience in the best restaurants in the world or someone who knows somebody. So start working at the best possible place you can, whether thats the best restaurant in your small town or w/e, and work your butt off, make connections and maybe someday you can work in one of those kitchens. Places like Alinea have waiting lists for people that want to work there, and every person on that list has already worked at a couple michelin starred places. El bulli brings in only like 40-60 cooks a season with them getting about 1000 resumes for each one of those spots. As far as schooling goes, go to a place that offers degree programs in culinary and and get an AS in Culinary and a BS in nutrition, management, etc.
