I frequently receive emails from potential M.D.-Ph.D. students seeking advice on career decisions. Below is a summary of the common questions about pursuing research in machine learning for healthcare and insights into my career path. I hope you find this helpful, and please feel free to email me hyewonjeong.contact@gmail.com if you have further questions (I might not be able to respond quickly but will try hard to respond quickly).
Answer: While having an MD can certainly help in understanding the domain, students without an MD can also conduct research effectively. They can collaborate with healthcare professionals and gain a solid understanding of the research problems, making an MD not necessarily essential.
I have received a lot of questions asking "Is M.D. Ph.D. worth it?". Well, I didn't think about it being worth it or not, I just wanted to do research and that was one of the few paths I could choose, and I liked the path. People say given the time it might not be worth it for some people and it will never be worth it.
Answer: As I am not a professor directly involved in selecting PhD students, it's difficult for me to provide a definitive answer. However, having research experience is likely to be important.
