That's awesome! It's so cool to meet you! Good luck with the MMIs, I'm sure you'll get an invite, and that you'll have the professional attitude they are looking for. Also, your interest in regenerative ranching is so unique. I honestly had to google the term to find what it was. I bet UC Davis is the best place for that.
I'm from Greece; I got my MD there. My Ph.D. was on neonatal encephalopathy, and since then I've been doing basic research on neonatal brain injury.
I applied this cycle and I am currently trying to fulfill some of their prerequisites... In Greece, the program is 6 years, and we got into advanced science courses like anatomy, physiology and histology from the 2nd year, so I don't have the 4 semesters of chemistry UC Davis requires x)
