How would minorities be successful with a degree in Biomedical Engineering?

You should first aim to be successful in BME because it's your passion, you're talented, and your goal is to persevere and achieve endless possibilities. The status of your ethnicity should be considered as a perk, that might present opportunities perhaps not available to everyone. However, other BME's could also have characteristics that might allow opportunities for them as well. It's nothing to be embarrassed about; it's one of the grandeurs of life.

I have a son in his 22nd year as a civil engineer and his firm is predominately Caucasian. Don't dwell on circumstances that are out of your control, as there are many professional careers with limited diversity in membership, as well as the work setting. The same was true for me many years ago as a clinical and public health dental hygienist and a school counselor within the last 35 years. There are professional organizations with subgroups for minorities, but not all.

If you are concerned about the diversity of the profession, perhaps you should focus your job search, when that time comes, on companies that hire a large percentage of minorities, or those located in large diverse cities. However, those restrictions could prevent you from embracing an outstanding career in BME and reaching your full potential. Remember, it's not so bad, sometimes, "being the only one." On the other hand, if this is a serious concern, perhaps you need to consider a different career. However, just think how disappointed you may be later when you discover that you couldn't fulfill your career goal because you were afraid to "step out of your comfort zone."

Hope this helps!

BME, and even engineering in general, can be very challenging but also very rewarding. Keep in mind that there are quite a few inclusion professional organizations that it would be worthwhile to join for support and mentoring. For instance, there's the Society of Women Engineers, National Society of Black Engineers, American Indian Science and Engineering Society, Mexican American Engineers and Scientists, National Organization of Gay and Lesbian Scientists and Technical Professionals, and the Society of Hispanic Professional Engineers, among others, that are just for minorities. The Biomedical Engineering Society also has minority resources. Don't neglect these resources!

As black male who graduated with engineering degrees and worked as an engineer and other roles in technology, I can say that while it's true that there are few minorities in the field, it is definitely worth considering. There are an amazing amount of opportunities to become successful in careers in the STEM field, and I can't stress enough how large the support network is becoming for minorities in STEM. Biomedical engineering a growing field, with many new companies popping up trying to address some of the world's most challenging problems. There are quite a few people of color who have contributed greatly in the area, and they've found that their backgrounds can sometimes be assets. Whether that's working on a problem in a different way, or helping organizations to acknowledge that there problems unique to minority communities that are underrepresented in the areas of focus.
While I don't think that careers in STEM are right for everyone, don't let the ethnic composition of the field deter you.

Best of luck!
