Genetics

Through internship, I am assuming that you're interested in doing some research work or project, so the best way is to start looking for nice institutes nearby your places where you can easily visit, then check the faculty of desired topic, and the professor you would like to work with, you can send them a mail including all the skills you've and why would you like to work with them. If they like your CV and statement of purpose they will respond you back positively otherwise you can try to other too, there is always a way if you're interested a lot to work upon something. Also, you can apply for summer internships through INSA where you can also get a scholarship to work and you can also go to some other cities with full scholarship for that summer internship.
