In 2001, Dr. Mallory joined the Baylor College of Medicine pediatric faculty and with Dr Dean McKenzie helped to establish the TCH Lung Transplant Program. The program was approved in 2002. Since that time, the TCH Program has become the most active program in the world with 8 to 20 transplants performed per year with the lowest wait list death in the nation. Over the last ten years, the TCH program is one of only three programs consistently performing lung transplants in infants and young children. The number of original publications and review articles from members of the medical and surgical teams exceeds every other program over the last decade. Jeffrey Heinle MD is the surgical director of the program. Tina Melicoff-Portillo is poised to become the Medical Director in early 2018 as Dr Mallory moves toward emeritus status. 

Since 2005, Dr. Mallory has also been medical director of the region's only pediatric pulmonary hypertension program, which was certified in 2017 as a pediatric clinical center by the Pulmonary Hypertension Association. Dr. Nidhy Varghese became the Medical Director in 2017 as Dr. Mallory stepped aside while staying active in the clinical and research activities of the program.  Dr. Mallory turns 70 years of age in 2018 but is planning on contributing time, energy and expertise to the programs and the Pulmonology Section for at least two more years with an emphasis on lung transplantation and pulmonary hypertension.

Dr. Mallory is a dedicated editor and teacher. He co-edits the pediatric pulmonology section of UpToDate. He has been on the editorial Board of Pediatric Pulmonology over 25 years and reviews dozens of papers for several professional journals each year. He is heavily invested in the education of pediatric pulmonology fellows and pediatric residents at Texas Children's Hospital.
