A graduate from the Universidade Federal do Rio de Janeiro, Doctor Fernando Santini started his residency with the medic clinic at the Hospital das Clínicas da Universidade de São Paulo and soon afterwards did another residency specialized in hematology and hemotherapy at the very same hospital. In 2010, he worked at the Instituto do Câncer do Estado de São Paulo with their recently established lymphoma department, where he decided to dedicate himself to oncology. With that new goal in mind, in 2011 he started working at the Hospital Sírio-Libanês through a residency at their oncology clinic. He moved to New York in 2014 to specialize in thoracic oncology at the Memorial Sloan Kettering Cancer Center. He returned to Brazil in 2017 and is currently working at the oncology center at the Hospital Sírio-Libanês, where his main field is thoracic oncology.
