Osvaldo Duran-Melendez, M.D.
Duran-Melendez earned his medical degree at the University of Puerto Rico (UPR) School of Medicine. During medical school, he was selected to become a member of the Gold Humanism Honor Society. He completed his residency with the UPR Emergency Medicine residency program, where he was an academic chief resident. As a chief resident, he helped develop academic curriculum and coordinate simulation trainings. In addition, the UPR was also the school where he received his Bachelor of Science in Mechanical Engineering degree. Recently, he finished an ultrasound fellowship with the University of Florida Department of Emergency Medicine.
By studying mechanical engineering, Duran-Melendez had the opportunity to learn about the medical devices industry as well as take courses in biomedical engineering and human anatomy. These experiences helped him discover medicine as a career option. His attention was first captured by emergency medicine, and then it gravitated to critical care medicine as he became more interested in the research and patient cases.
Through volunteering, Duran-Melendez has provided services and resources to communities hit by natural disasters. In 2020, he joined a medical brigade, tasked with helping earthquake-impacted communities in Peñuelas and Guánica, Puerto Rico. During this time, he provided health checkups and vaccination services to individuals.
In his spare time, he enjoys reading fantasy books, watching anime, and playing tennis.

He completed his emergency medicine residency at the University of Texas at Austin Dell Medical School. He received his Bachelor of Arts in Psychology from Arizona State University.
Oliver’s experience as an emergency medicine physician has furthered his interest in critical care medicine. He looks forward to the procedures and caring for critical patients. For his fellowship here, he hopes to improve his procedural repertoire and strengthen his leadership and teaching skills.
During Oliver’s time in medical school at CUSM, he founded and directed a program, called VIDA, that sought to increase the quality of healthcare services for Hispanic patients. For the VIDA program, he wrote grants and budget proposals as well as collaborated with university leadership to create an immersive medical school curriculum.
In his residency at Dell Medical School, Oliver helped the medical school with its admissions process. He interviewed medical school candidates and led social events for the prospective students.
