Erard graduated from the Free University of Brussels (ULB) first as a medical doctor in 1995 then in 2000 as a specialist in nuclear medicine. During his training and after a short passage through the oncology department in Johns Hopkins (USA), Erard mainly performed his training at the Institut Jules Bordet, one of the most famous and important oncology centres in Belgium. Since his graduation, Erard has continued working mainly in the field of cancer. Erard also has the opportunity to write some texts in medical blogs and internet newspapers for the lay public about the evolution and the future of medicine. Through his practice, Erard gradually understood the need from patients to better understand their disease but also to be able to discuss without complex and barriers personal issues with people from the medical and non-medical field.
