I'm an MBA student applying to MD/PhD programs this summer. I've enjoyed it and definitely learned a lot. Diversity of experience makes you a better scholar (and consequently researcher) in virtually any field, science included. During these 2 years I've still been neuroscience research, and actually have another 1st author paper to submit in the next week or two. I've also taken some grad level computer science courses on the side. If you want to talk more about why I've done this and how I'm going to explain myself during applications, let me know.
Why are you looking at this?
