Hi, I worked for a professor the summer before my college freshman year in a molecular biology lab. This lab work is totally unrelated to the research I do now, but it is more similar to the type of research work I think I'd like to pursue as a MD/PhD. I've looked at MSTP websites at the med schools I want to apply to and some of them indicate that letters of recommendations are required from all research supervisors. So, would this include the professor I worked with after high school? I haven't talked to this professor for two years now, so I'm not sure if he remembers me well. So, I'm not sure how to approach him for a letter of recommendation. Any suggestions? On a different note, I think I'm going to apply both MSTP and MD-only to UT Southwestern, UTMB and UT Houston. If I submit my AMCAS application in early June and my Texas application in early July, how would interviews work? Are MSTP and MD interviews usually on the same day?
