As a young physician at Louisiana State University, Dr. Bonilla focused on the Clinical Management of HIV/AIDS and HCV, two neglected and stigmatized diseases for which effective therapies were in their infancy. While learning the clinical aspects of the two diseases, Dr. Bonilla saw a need to create and organize a support community to promote understanding and management of the conditions. Subsequently, he went to Summa Health System in Akron, Ohio, and he continued his work where he specialized in HIV/HCV as well as in Infectious Diseases Clinical Practice. In addition to teaching medical residents and students, Dr. Bonilla participated in numerous clinical trials and developed clinical research projects. Furthermore, he led the Infection Renal Transplant Program, HIV and HCV clinics, and he participated in several cooperative studies with Case Western Reserve University. Dr. Bonilla’s interest in academia led him to the University Of Pittsburgh Medical Center where he was an Assistant Professor, Clinician, and Medical Educator in the Department of Medicine in the Division of Infectious Diseases. Due to his interest in cytokines and immunological responses, Dr. Bonilla became a researcher at ImmunoScience Inc., a biotechnology company in California that works to develop a therapeutic HIV vaccine. Dr. Bonilla’s experience of treating HIV/HCV combined with his interest in inflammatory response is the driving force behind his desire to understand ME/CFS. Dr. Bonilla is a strong patient advocate, and he believes in integrated care—care in which physicians communicate and coordinate efforts to deliver the best medical outcome for patients. His ME/CFS patients are his inspiration, and he is committed to continuing research to seek answers to their health challenges.
