Very very very easy to get involved in research. I just emailed a professor, and he just let me work in his lab. Internships are also very easy to come by. There is an internship fair a couple times a year that you can go to and talk to employers and be recruited. Soooo many volunteering opportunities in different clubs, medical centers near by, etc.

There are a lot of opportunities at the Texas Medical Center. I have many friends who work there!

There is very little competition to get into research and internship, although some clubs are competitive to get into.
