Mireia Camós, PhD.

Coordinator of the CLOSER research project

My name is Mireia Camós. I hold a degree in Medicine and Surgery, I am a specialist in Hematology and Hemotherapy, and I hold a PhD in Medicine. I currently work as a senior hematologist at the Hematology Laboratory of Hospital Sant Joan de Déu in Barcelona. Since 2019, I coordinate the CLOSER research project on childhood leukemia.

I have always tried to give my best at work, in the clinics in the past and now in the lab. If I see something that can be improved, I try to improve it. Once my boss told me, “You’re a person who makes things better wherever you go.” I think that is the nicest thing someone has ever said to me professionally, and it made me feel very proud.

Ever since I was a kid, I wanted to be a doctor. I loved seeing patients in the past, and I love doing diagnosis and research now because I feel I can somehow contribute to improving patients’ lives. My job is tremendously enriching, mainly through human contact. Every day you can learn from your peers, patients and families…
