Luis "Lou"’s Answer
Biomedical engineering has to do with a lot more than just stem cell research. It is a very broad field with many different areas that one can focus on. Stem cell research has more to do with Genetics than biomedical engineering. If you are interested in Genetics, a degree in Microbiology, Chemistry or Medicine would probably be more appropriate than Biomed. You can then focus in Genetics, Genetic engineering or Genetic medicine.
