In that first few months as a medical student I remember a day just as clear as if it was yesterday, where a pediatrician came to talk to us, and he brought with him a couple of patients who had genetic diseases. And it was so powerful to see the consequences of a small change in this wonderful molecule called DNA. Just one letter out of place causing a disease like sickle cell anemia, which was one of the individuals that he brought, or galacticemia, a newborn baby that he brought to class. And that, maybe because it also appealed to the mathematical part of me that liked the precision of DNA and its coding capacity — it’s a digital molecule after all — made it so clear at that moment, that day, that’s what I want to do.
