Tell us a fun fact about yourself.
I grew up aspiring to become an architect. It wasn’t until I took organic chemistry in college that I discovered my interest in science and medicine. I was later drawn to radiology when I recognized that it requires much of the same spatial reasoning and intuition as architecture and organic chemistry.
