Dr. Xi Ma is originally from China and received his initial public health training at the Peking University Health Science Center in Beijing. Drawn by the opportunity for the harmonious integration of oncology, cell biology and molecular biology, he completed his medical immunology fellowship at the Peking University Health Science Center. He has been a faculty with the China Agricultural University and an Associate Professor since 2012 focusing on the research of animal nutrition requirements and metabolic modulation. Dr. Xi brings to UTSW a strong background in mammalian metabolism and nutritional modulation, intestinal barrier and immunology. He currently specializes in biochemical mechanism of mammalian autophagy and nutritional modulation. Dr. Xi’s interests outside of medicinal research include his family, reading, and the great outdoors.

Research Interest

  • Biochemical mechanism of mammalian autophagy and nutritional modulation
