I have a Ph.D. in Engineering and I figure a medical degree will be highly valuable to gain a better understanding in my research area (biomedical/neuroscience). However, unlike science/engineering graduate schools, medical schools do not pay your tuition and financial assistance is primarily need based, rather than merit based.
Are there avenues for an interested candidate to pursue a medical degree in the US (perhaps part-time, while working as a post-doc in a relevant field) without taking on significant amounts of debt?
