For this Faculty Feature, we spoke with Eleanor Castro MD, Assistant Professor, Pathology & Immunology in AMP with clinical interests in Gynecological and Breast Pathology.
Tell us about your background. Where did you grow up, and when did you first become interested in science and medicine?
I was born and raised in Louisville, KY where I also went to undergrad and medical school. I gravitated toward biology and anatomy in high school which led me to consider medicine as a career path. I became interested in pathology during my second year of medical school. My favorite lectures during second year were taught by pathologists and a few of them took time during their lessons to talk about the field of pathology and what they love about their job. I spent as much of my elective time with the pathology department as I could and was quickly convinced that it was the right fit for me.
What is your career path?
I went to medical school at the University of Louisville in Kentucky. I came to St. Louis when I matched into the residency program here at WashU. During residency I had great mentors who sparked in me a love of breast and gynecologic pathology. This led me to pursue the combined breast/gyn fellowship here in 2023/2024. I now look forward to contributing to the department as a faculty member as a I continue to grow as a pathologist and teacher.
What are your favorite parts of your current role?
One of the most fulfilling parts of my current role is working to solve diagnostic problems that make a direct impact on patient care. I enjoy the challenge of working on complex cases and following up to see how the treatment plans for our patients unfold. I also enjoy the opportunities for teaching and learning both in and out of sign-out.
What is a memorable moment you’ve had while working in the department?
I think so far, my most memorable moment has been making the transition from trainee to faculty member. I really appreciate how welcoming and supportive the trainees and fellow faculty have been.
What are some of your favorite hobbies or activities?
I love hobbies that involve working with my hands including knitting, gardening, and baking. Layer cakes are my favorite thing to bake. I’ve made lots of birthday cakes for friends/family and even three wedding cakes! I’m also an avid reader/audiobook listener. My favorite genres are sci-fi and fantasy.
What is your advice to aspiring people in your field?
My advice to aspiring pathologists is to stay curious and open to learning—whether through formal education, hands-on experience, or collaboration with colleagues. Don’t be afraid to embrace challenges and pursue areas of research or subspecialty that truly interest you. Finally, remember the importance of mentorship, both as a mentee and eventually as a mentor, because learning from others and guiding the next generation is an invaluable part of professional growth.
