What is the speaker’s field of study?

Born and raised in central Ohio, I’m a country girl through and through. [18] I’m currently studying to be- come a physical therapist, a career path that marks a great achievement for me. At Ohio State University, ad- mission into the physical therapy program is intensely competitive. I made it pass the first cut the first year I applied, but was turned down for admission. I was crushed, because for years I have been determined to become a physical therapist. [19] I received advice from friends and relatives about changing my major and finding, another course for my life.  I just couldn’t do it. I knew I could not be as happy in another profession. So I stilled myself, began to work seriously for another year and reapplied. Happily I received notice of my admission. Later, I found out that less than 15% of the applicants had been offered positions that year. [19] Now in the first two years of professional training, I couldn’t be happier with my decision not to give up on my dream. My father told me that if I wanted it badly enough, I would get in. Well, Daddy, I wanted it. So there. After graduation, [20] I would like to travel to another country, possibly a Latin American country and work in a children’s hospital for a year or two. So many of the children there are physically handicapped but most hospitals don’t have the funding to hire trained staff to care for them properly. I would like to change that somehow.
