Looking for an internship.

Hello everybody. I'm looking for an intership for next year and I've I have to (when using "to have" to express obligation, we don't use the contraction) do a message in English but I don't know if there is some mistake, are any mistakes; it have has to be professional!

I'm looking for an engineering internship in research and developpement development for next year. I am studying chemistry and will specialize in polymers. I'm passionate in about sports and want to apply my scientific knowledges in order to improve the pratic of sport practices in the field of sports (it is probably better to write simply "practices in this field" in order to avoid repetition).

 (Good luck in your search for an internship!)
