Well as for the DBA, I have dual interests. I am in South Korea and have been teaching English, though I want to teach Business which requires a doctorate. Obviously the problem with taking classes and being outside the US is not being able to attend a brick and mortar school. The school I went to for my MBA has classes both in a regular setting, online, and then compressed weekends (meaning you attend one weekend for three days straight, which I did once and didn't like much). A few of my MBA course were online, most of them were at the school. So I felt comfortable taking online classes.
The other part is that I have this sick fascination with food. No really I'm serious. Ok, maybe not food, but retailers. Seriously I am interested in the international retail industry in South Korea. Many international companies have tried to enter the market and have been unsuccessful (most notably Wal-Mart and Carrefour) while others have had wonderful success (Tesco and Costco). My dissertation will be a qualitative study on international retail market entry in South Korea. I find the applied research more interesting.
