Buka Samten completed his medical education at Xinjiang Medical University and his MS degree in Immunology at Beijing University School of Health Sciences in Beijing, China. He had lectured immunology and experimental immunology to the medical school students and graduate students at these universities as an Assistant Professor after his graduations. In 1998, he had joined the research group at the Center for Pulmonary and Infectious Diseases at the University of Texas Health Science Center at Tyler (UTHCT) as a postdoctoral research fellow. Since then, he has conducted scientific research to understand the immune responses against tuberculosis infection. He was appointed as an Instructor of Microbiology and Immunology in 2002, Assistant Professor in 2006, and Associate Professor in 2009 at UTHCT.

His research has focused on understanding the defects in immune responses of tuberculosis patients by examining the intracellular proteins of T cells of tuberculosis patients. He has also studied the effects of major virulence factors of tuberculosis pathogen, Mycobacterium tuberculosis, on immune cells, such as T cells, dendritic cells, and macrophages. His research was supported by the funds from the Presidential Research Council of UTHCT, the Potts Memorial Foundation, and the grants from the National Institutes of Health. He has published over 60 research papers in peer-reviewed scientific journals, made numerous posters and oral presentations, and given invited talks at the national and international scientific meetings. He serves as an ad hoc grant reviewer for the American Heart Association and NIH study sections. He has also served as an ad hoc manuscript reviewer for several scientific journals in the field of infection and immunity.

He was awarded the Keystone Symposia Scholarship by the Keystone Symposia and Junior Faculty Travel Award and Laboratory Travel Grants by the American Association of Immunologists. His research interests include T cell immune responses against microbial pathogens, the interaction between Mycobacterium tuberculosis, the pathogen, and immune cells, and development of novel anti-tuberculosis drugs.
