I don’t know if MD-Phd is on your radar, but keep in mind that funding for these programs might not exist moving forward. I have a family member who recently graduated from an MD-PhD program and they lost funding.
You can be involved in research with a masters, or do a combination of patient contact and research, publishing etc. You have time to sort this out. Research funding is not what it was, but it does still exist in certain careers.
Besides Pitt and UDel, you might look at the University of South Carolina, and Ohio State. Rochester is a great school but it’s very expensive- use the NPC.
